Earlier this week I received an invitation to attend the North American launch of the new Campagnolo EPS system. I doubt Campagnolo has introduced anything that has ever been as eagerly awaited as this group. And with good reason; we’ve known that the heralded component maker has been working on this for ages. The’ve had more than adequate time to build interest.
Now let me say that I first heard about Campagnolo working on electronic shifting back in 2002. By that time, apparently, the prototyping on this group was old news. What I found out during the presentation was that they’ve been working on electronic shifting since the days of the first 8-speed Ergo levers. How was that not more widely known? I’m sure some Campyfiles must have known, but I hadn’t heard a word about it in the ’90s.
So why did it take so incredibly long to bring the group to market? Campagnolo was limited by the electronics technology available at the time. They literally (and I do mean literally) had to wait for the technology to be developed that would allow them to implement a design that was small enough, light enough, robust enough and smart enough to get the job done.
Before I dive too deep, a note on the nomenclature: EPS stands for Electronic Power Shift. Nice and straightforward.
I had the chance to look at it up close and to ride a bike with it on a trainer. My overwhelming reaction to it is one of sophistication. Shimano’s Di2 has not been without its criticisms. The group is heavier than mechanical Dura-Ace and reports circulated the riders using the group at the cobbled classics experienced bump-induced shifting. EPS feels like shifting; there’s actual lever movement and in that I believe Campagnolo got the single most important element of electronic shifting right. You feel like you’re using bike components. Further, the Super Record and Record EPS groups are lighter than Di2. Record weighs in at 2098 grams Super Record tips the scale a bit less at only 1875g.
The touch is light and the speed of the shifts is noticeable, but it’s not blink-your-eye quick. And if you’re anything like me and completely in love with the shape of the current Ergo lever, you’ll appreciate that this is exactly the same as the mechanical levers, though the texture of the hoods is a bit different.
Battery life is impressive. Last year the Movistar team used the groups and we were told they charged the group’s power units only three times through the whole of the season. The case itself is pretty impressive. It’s ultrasonically welded shut to keep the elements out and the electronics are cushioned from road vibration to increase their life span and reduce the chance that impacts will damage a component.
One interesting detail we learned about the group is that while you can downshift three cogs at a time and upshift five cogs at a time with mechanical groups, you can cycle all 11 cogs in either direction with EPS. Cooler still, we were told it takes only 1.5 seconds to shift through all 11 cogs.
When Campagnolo North America’s Tom Kattus invoked the name Syncro during the presentation, I admit I nearly fell out of my chair. For those who don’t recall, Campagnolo’s first effort at indexed shifting required a slight overshift before the lever settled into position. To say it was wonky would be diplomatic. That idea has been revisited with EPS—the front derailleur does an overshift automatically on upshifts. The idea is that if you combine a 40 percent increase in torque with a slight overshift you’ll get perfect shifting every shift, but you’ll also get a speedier shift, too. It makes sense when you think about it. Move the chain over just that much more and it will catch that much sooner.
The EPS Interface mounts easily on the stem, making adjustment easier to do on the fly (should you actually need to make an adjustment while riding) as well as making it easier for you to monitor battery charge from the saddle. It’s unlikely that battery charge will be a big concern when you’re out on rides, but should you start a long ride with a relatively low battery level, you will know where you stand thanks to the LED light on the left of the unit. It features five levels (bright green, blinking green, yellow, red and blinking red with a buzzer) that correspond to relative battery level.
I’ve been critical in the past of how much carbon fiber Campagnolo uses in its groups. My feeling has been that in some cases while the carbon fiber makes the component lighter, it also makes it unnecessarily fragile. The derailleurs have been my two big criticisms. That said, I’m fascinated with the way carbon fiber has been used in the bodies of these derailleurs and I don’t suppose they’ve gotten any more fragile than they were. I look forward to learning more about their manufacturing. What I really can’t wait for is a chance to ride this stuff.
The years went by, I kept riding my bike, but I still have no hoverboard. Corporations: If the hoverboard is real, please don’t release it. I have kids now, I understand.
Over the years, I’ve followed a number of the technological advances that were supposed to be just around the corner for bikes that excited me almost as much. One of the biggies was electronic shifting. Electronic shifting, from Mavic, really never felt like it was going to take off. Finicky, prone to malfunctions, expensive—when it worked, it was great. When it didn’t, it was a mess. I figured electronic shifting would never hit the mainstream.
Then Shimano Di2 came out. Campagnolo EPS, 10 plus years in the making, was available. With the release of Ultegra Di2, its safe to say electronic shifting has left the realm of just around the corner, and hit mainstream. Sometimes, the advances we think will never come really do become reality.
The other big item I’ve been waiting for is disc brakes on road bikes. You’d think, being a well understood technology, we’d have them by now. With them now legal for cyclocross, it may just be a matter of time—mechanical discs are already making inroads, and while solutions for using hydraulics are a little hokey now, we’ll probably see something available sooner or later. If I keep saying any day now, sooner or later I’ll be right.
One thing I never saw coming was hydraulic rim brakes. I’m trying to decide if they are a technological advance, or just a Mektronic on the path to disc brake Di2. Or EPS—no allegiances here.
Magura’s announcement as a sponsor for Garmin-Barracuda started the rumors flying. Magura confirmed their re-entry in to the road hydraulic market with a hydraulic rim brake, the RT8, initially available as a time-trial only version (RT8TT) mated to the Cervélo P5 time trial frame. In a few months, we’re told, it’ll be available without the Cervélo for both road and TT use. How that’ll work in a world where most people use integrated brake/shift levers remains to be seen. Details are just around the corner, I’m sure.
Before we discuss the merits of Magura’s offering, it’s worth understanding a little about hydraulic brakes. For the dirt-phobic, this may be the closest you’ve come to them, and while it’s unlikely you’ll be seeing Magura’s offering on your group ride any time soon, you’ll probably hear discussion about it.
Hydraulics are pretty simple. A typical hydraulics system of any form is composed of a master cylinder, one or more slave cylinders, incompressible fluid like mineral oil or DOT, and hydraulic cable to connect them. Each cylinder contains a piston. Press the piston in the master cylinder in, the incompressible fluid moves out of the master and in to the slave, and the slave piston extends. Simple. Attach a brake lever to the master cylinder piston, and use the slave cylinder to actuate a brake pad, and you have the makings of a hydraulic brake.
There are two different kinds of hydraulic systems employed in bikes. Most hydraulic discs use the “open” system, where there’s a reservoir attached to the master cylinder to manage fluid fill levels in the system itself. Lots of braking can heat the fluid, causing it to expand and overfill the system. The same excess braking also contributes to pad wear, requiring more fluid in the system. The reservoir takes care of managing these levels.
In a closed system, there’s no reservoir. Just the master cylinder and slave cylinders, and a fixed volume of fluid.
Left by itself, pressing the master cylinder piston in moves the slave piston out, where it will happily stay. The “normal” solution involves using specially shaped gaskets, designed to “twist” along with the piston. When there’s nothing pushing on the master cylinder piston, both pistons will want to retract to their normal positions, giving the behavior you expect from brakes. Springs occasionally augment this sort of system.
The upsides to hydraulic brakes are numerous: low friction, one-finger braking. Great modulation and control. Consistent performance, devoid of changes due to cable stretch or wear. Most of all, they’re powerful—by tweaking the ratios of width and height between the cylinders, a mechanical advantage is achieved—1 pound of pressure at the master cylinder can exert many multiples with a proper design.
The new RT8 brakes are a somewhat unorthodox brake design, if we confine ourselves to the notion of how disc hydraulic brakes work.
Magura has had a rim brake product line for years, targeted at the tandem market. These offerings, and it appears the new RT8 as well, utilize a “closed” hydraulics system. The master cylinder has no reservoir. This isn’t necessarily a problem, assuming environmental conditions stay pretty constant; heat generated by braking shouldn’t feed back in to the slave cylinder the way it might in a disc system, which directly actuates the pad. Pad wear is still something of an unanswered question in the RT8—this could very well be handled at the brake lever by adjusting the travel of the lever blade, or limiting the retraction of the piston.
So is it better?
Magura’s brake should offer stronger, quicker actuation with less effort than a typical brake. Depending on the terrain you ride, this may be a major advantage, or make no difference at all. For the cyclist who finds them selves climbing—and therefore descending—major heights, hand fatigue may be a serious problem. We haven’t seen a road brake lever yet from Magura, however. At the moment, unless you find yourself regularly descending on your time trial bike, this likely isn’t a major problem.
Power isn’t a major issue with modern road brakes. Enhanced modulation may allow a lighter touch ducking in to corners, and that could possibly lead to some speed advantages for the racers among us. Possibly. With situations where the brake selection itself is causing braking problems, then the RT8 might be a major advantage—with some time trial bikes utilizing low-travel lever blades connected to center pull and single pivot designs to smooth cable routing and reduce frontal profile, the uncompromising power of the RT8TT will be a welcome change.
Aerodynamics have been heavily touted for the RT8′s, with Cervélo playing a role in their design. It’s not an advantage afforded to it by being hydraulic, but may shave precious microseconds off times. We’ll have to wait for some testing to confirm this.
The Magura design may have one neat side effect. It hasn’t been discussed, but the closed hydraulic design of the RT8 may allow for multiple master cylinders. In an open system, where the master cylinders have reservoir, having a one master cylinder compress will cause the other’s reservoir to, over time, soak up the excess fluid in the system. In a closed system, so long as there’s no air in the system, there’s no place for the fluid to escape. Bleeding the system would bring new levels of pain to an at times trying process, but in theory, once its set up, it would work fine. I’m certainly curious to see if anyone is going to try mounting brakes on both their base and extension bars in a time trial. The ability to brake from the extensions and maintain an aero position could be an genuine advantage.
It’s less clear if the Magura brake will help with are the major issues big descenders have: rim sidewall damage, wearing out pads, and blowing out tires. Discs, by relocating the braking surface away from the tire, are the best hope we have for solving that issue once and for all. That and better technique.
Under certain conditions I can see some potential upsides to Magura’s RT8 brake. Quicker actuation, more power and better modulation with less fatigue sounds like a win, if these are problems that plague you. Improved aerodynamics don’t do much for the recreational cyclist, but may be a win for those at the point where fractions of seconds matter. The multiple lever concept sounds cool, but whether anyone cares remains to be seen. We’re still left using the rim for a braking surface, though the enhanced modulation the Magura should offer might compensate a little for those with marginal descending technique.
It’s an interesting product, and one I’m curious to hear more about as details emerge. It’s unlikely, however, to satiate my desire for discs—or hoverboards.

We decided to do some year-end awards here at RKP, but because we don’t see much point in awarding someone “best Danish single-speed cyclocrosser with no ink”, we figured we’d give some nods to those people, events and moments most memorable. And to add to the fun, we invited Whit Yost and Jeremy Rauch from Pavé to join in the fun.
So here we go:
Rider of the Year—Despite not notching a win another monument this spring, by virtue of the fact that Fabian Cancellara finished on the podium in Milan-San Remo (2nd), Ronde van Vlaanderen (3rd) and Paris-Roubaix (2nd), he proved to be the strongest rider in this year’s spring campaign. That Cancellara was chased as if an attack from him was everyone else’s ticket to glory was unseemly. It appeared—given those who latched onto his wheel—he was chased less to prevent him winning than as a springboard to anyone else’s.
Most Valuable (Non) Player—This has to go to Francesco Moser for doing more to liven up this year’s Tour de France short of any rider other than Thomas Voeckler. By instructing the Schlecks on how to win at bike racing, Moser inspired Andy Schleck to take the single most interesting flyer at this year’s Tour. Frankly, it did much to illustrate the criticism that due to radios riders no longer know how to ride tactically. The greater lesson is just how the greats were. How about a mentoring program for today’s GC riders? The racing might get more interesting if we dusted off more GC champions from the ‘70s and ‘80s.
The We-Don’t-Know-What-to-Call-It Award—Thor Hushovd has easily been the peloton’s biggest crybaby for the last two seasons. Of his seemingly endless skills—honestly, has anyone else delivered more unexpected and surprising wins?—diplomacy isn’t one. He may be the only guy who could teach Bradley Wiggins a thing or two about badmouthing a previous team. That said, his cunning has proven he is more than worthy of both protection and a free hand. Maybe we should call this one the Wild Card Award. You just never know with this guy.
The Mad Ambition Award—This goes to Jim Ochowicz and the rest of the management at Team BMC. On one hand, they are geniuses for vaulting BMC to the top of the pops in just two years. Their ability to sign riders of real quality was confirmed in a royal flush back in July when Cadel Evans finally won the Tour de France. So how they managed to court and sign both Philippe Gilbert and Thor Hushovd can’t simply be magic; it’s more like sorcery. Evans was on record saying anyone on his Tour team (and it is his Tour team) won’t freelance, won’t go for stage wins and will bury himself for the team. Somehow Gilbert and Hushovd—who between them took three stages of this year’s Tour—claimed they were okay with that. We also give this the Most Likely to End in Tears Award.
The Most Coveted Award—This has to go to Zipp for the new Firecrest 303. There’s not another set of wheels I’ve heard spoken of with a more covetous tone than the redesigned Firecrest 303. Lighter than a supermodel’s brain, more aerodynamic than a Cessna and more durable than any aluminum rim you’re riding, the only question is who doesn’t want this wheel.
The Relief Award—Bike fans breathed a collective sigh of relief with the announcement that Campagnolo will finally begin selling its long-awaited electronic group, EPS. Though we heard that the Italian maker was working on this group back in 2002, Shimano came to market with Di2 a full two years ahead of Campagnolo. This is quite a contrast from the introduction of index shifting and integrated control levers. Shimano’s stuff may have worked better in both instances, but at least Campy had a ready response. The good news is that EPS seems to be kink-free, so this year you’ll be able to enjoy electronic shifting and 11-speeds all in the same group.
Worst News of the Year Award—The demise of HTC-Highroad. To have Bob Stapleton depart cycling is the worst news the sport will get for a long, long time.
The Textbook Courage Award—If you needed any proof of the talent at Andy Schleck’s disposal, his attack on Stage 18 from Pinerolo to the Galibier in this year’s Tour de France showed exactly what the young and often hapless Luxembourger is capable of. Down on GC and running out of road, Schleck had to do SOMETHING. What he did was one of the most courageous and awe-inspiring attacks we’ve seen this decade. First, Leopard – Trek put Joost Posthuma and Maxime Monfort into the break. Then, Schleck attacked with 60km to go, took a gap, stretched it to two minutes and then latched onto Posthuma and Monfort to stretch his lead, ending just 15 seconds out of yellow, as Tommy Voekler buried himself on the imposing slopes of the Galibier. This is the racing fans have always wanted from Schleck, but he has seldom delivered. Cautious to a fault, on this day Schleck was a legend.
The Have No Cake and Fail to Eat It Either Award—I, for one, thought it was a good idea for Zdenek Stybar to try his luck on the road, especially with a Classics-oriented squad like QuickStep. Unfortunately, Stybie flopped in his first season and has now relinquished his dominance of the Euro Cyclocross World Cup Series to Kevin Pauwels. What’s the Flemish for “Oops?”
The Straight Face Award—It’s been 18 months since Alberto Contador tested positive at the Tour de France. The saga of inaction since then is well-documented. Under WADA guidelines, it doesn’t matter how or why the “adverse analytical finding” came about, the rider should be suspended, and yet Contador has argued, with a straight face, that he deserves to ride, and UCI head Pat McQuaid has gone on as if the fleet Spaniard isn’t receiving preferential treatment. If we say up is down long enough, will we all learn to fly?
The Ricco Suave Award—This award is reserved for dopers who approach the rank stupidity of Ricardo Ricco in their efforts to cover their tracks and/or protest their innocence. This year’s award goes to Ezequiel Mosquera. After a positive test for hydroxyethyl starch at the 2010 Vuelta, at which he was runner-up, Mosquera cried foul. But the test for hydroxyethyl starch has been around a long time, and that substance’s use as a masking agent for doping products is well-documented. Compounding Mosquera’s guilt, one of his Xacobeo-Galicia teammates, David Garcia, also tested positive for the same substance at the same race. The Spanish cycling federation (RFEC) rewarded Mosquera’s cheating with a two year ban ON TOP of the 14 months he’s already been off the bike. The rider has said he’ll retire. Don’t do us any favors Ezequiel.
Cyclist of the year—All new cyclists. They may be annoyances right now. They might reduce our cool, bad-boy cred. They may do stupid things in the road, at lights, on the trail, etc. But they’re making the world a better place for us. Growing the sport makes the roads safer, will eventually make the public more sympathetic, and some day, some of them will be giving us their draft as they pummel us in their wake. Cycling is growing so much that some places, like New York City, are experiencing a backlash. I think the backlash will be shortlived. We’re going to win and all new cyclists are helping.
The “Why Would Anyone Need X” award:
This year saw a number of new technical innovations: some good, some bad, but all the victim of some variant of the pace-line putdown “Why would anyone need <insert component here>”. The list of what would surely be past winners is long and filled with the things we take for granted today, and would surely include clipless pedals (“Too dangerous in a crash!”), index shifting (“I don’t need click-shifting to find my gear!”), Di2 (“If I wanted to play video games, I’d just stay home and play Nintendo!”) and 6, 7, 8, 9, 10, 11 and yes, 12 speed rear clusters (“Why would anyone need more than 5/6/7/8/9/10/11 speeds?”).
2011′s award, based on the seemingly never discussions on the topic, goes to disc brakes in cyclocross. With a battle cry of “if they were good enough for De Vlaeminck*, they’re good enough to me”, the canti-devoted dismissed the disc as unnecessary – too heavy, too powerful, not hydraulic, and just plain pointless. It’s true that the disc options when using brifters are incomplete; quality cable actuated brakes like those from Avid aren’t quite as effortless as hydraulics, and the mechanical/hydraulic adapters look like a mechanical in the making. That said, any mountain biker will tell you there’s no denying the performance of discs in the muck. Wet or dry, discs just work. It’ll take a few years for vendors to come up with ideal, rather than adapted solutions to discs in cyclocross. But when they do, I suspect the naysayers will see their benefits and at the very least, wish they were on discs too. Hey, give me hydraulic brifters, and I just might be willing to move off this 9 speed setup – because really, more than 9 speeds is silly, but disc brakes are awesome.
The shut-up and ride award—By now, we’ve all seen the video of Juan Antonio Flecha and Johnny Hoogerland getting whacked by the errant media car in Stage 9 of this year’s Tour de France. Both men suffered injuries that would have sent most of us crawling into an ambulance or at least the broom wagon. What was impressive, though, is that both of them got up, finished the stage and then made it all the way to Paris nearly two weeks later. It’s a story worth bringing up next time one of your non-cycling friends tries to tell you that American football players are the toughest athletes on the planet.
The great French hope—It was fun to watch Thomas Voeckler reprise his 2004 role as the beloved – but doomed – defender of the yellow jersey. (Voeckler actually earned the jersey as part of the aforementioned break from which Hoogerland and Flecha were taken out.) Voeckler is now 32 and his years may be numbered. It was inspiring to see the entire Europcar squad rise to the occasion and protect the jersey for 10 stages … all the way up to stage 19 when another member of the team earned the spotlight and maybe even signaled the start of what would be a welcomed renaissance in French cycling. Pierre Rolland showed more than a flash of brilliance on the slopes of l’Alpe d’Huez, out-classing Samuel Sánchez and Alberto Contador atop that storied climb. Not only did he win the stage, he grabbed the best young rider’s white jersey for good and finished the Tour in 11th on GC. Like another promising young rider in the season’s final grand tour, you have to wonder what this guy could have accomplished had he not been saddled with domestique duties for most of the race.
Maybe, just maybe, we will see an end to the French drought at the Tour, a race the hosts haven’t won since 1985.
Out of Africa―Having grown up in in Kenya and South Africa, Chris Froome showed he was more than able to meet the challenges of the European peloton in this year’s Vuelta a España. Froome finished second in the Vuelta and one can only imagine how the 26-year-old Team Sky rider would have fared had he not been obligated to ride in support of Bradley Wiggins at critical moments in that grand tour. As is the case with Rolland, I’m looking forward to seeing Froome ride without other obligations holding him back.
The No-Man-Is-an-Island Award―This last one is purely personal. Not to beat a dead horse, but I’ve hit a few rough spots over the past few months. Had you told me in January that things would have taken the turn they did in July, I would have predicted that I would just curl up in a ball and stay in bed. The darn thing, though, is that there are folks out there who just wouldn’t let that happen. Anything that I’ve accomplished or anything positive that has happened to me over the past months is purely due to the fact that people have been generous and spectacular. I have to extend my thanks to a host of people, including the gang over at NYVeloCity.com, their readers, the folks who follow me at LiveUpdateGuy.com, countless friends and family and, of course, those responsible for my new home here at Red Kite Prayer. I can’t even begin to count the ways that I have reason to be thankful. All of you gave real meaning to the words “cycling community.”
Most Disappointingly Successful Stage Race-Winning Strategy—Thanks to victories by Alberto Contador, Cadel Evans, and Juan José Cobo in this season’s grand tours, it was easy to overlook a rather unexciting “trend” in the art of winning stage races. Of the eleven non-grand tour stage races on the 2011 World Tour, eight had at least one time trial. Of those eight, seven were won by men who took either only the time trial or no stage wins at all, a race-winning strategy calling to mind Miguel Indurain.
Take Bradley Wiggins for example. The Brit from Team Sky won the Criterium du Dauphiné—without winning a single stage. The same can be said of RadioShack’s Levi Leipheimer at the Tour de Suisse. Both riders used top rides in individual time trials as the foundations of their victories then simply hung-on for dear life in the mountains. Of course, both victories were well deserved—after all, consistency goes a long way—but race fans can’t be blamed for wanting to see a bit more aggression from their champions. At least Germany’s Tony Martin actually won stages (both time trials, though) at Paris-Nice and the Tour of Beijing for HTC-HighRoad on his way to taking both overall victories.
What does it all mean? Not much, perhaps. But it could inspire more time trialists to find some climbing legs for a week every now and again. Or maybe a few of the sport’s aggressive riders might find themselves spending some time in the wind tunnel or behind a motor scooter, doing their best to defeat the sport’s Martin’s, Wiggo’s, and Leipheimer’s at their own game.
Then again, this is professional cycling—there are no style points. Victories bring contracts and unless your name is Thomas Voeckler, no one cares about how much excitement you generate in losing. We need to give credit where credit is due, but that doesn’t mean we have to like it.
