Battle Royal, Part IV: SRAM Red
Had it not been for the entry of SRAM into the world of road component groups there would likely never have been a reason for me to do this series of posts. It’s their presence that makes this question interesting. How SRAM even came to offer a road group makes this conversation all the more interesting. After all, if you were a cyclist in the late 1980s and ran across the early Gripshift units you can be forgiven for having concluded that SRAM would never make anything you’d willingly purchase. The shifters were wonky and bulky, and had to be positioned in a relatively inconvenient position. Even with a Shimano drivetrain the shifters required some fiddling.
Somehow, SRAM survived this first questionable product. They made acquisitions. Among their many acquisitions (which included Rock Shox and Truvativ among others) they picked up Sachs. You may recall that back in the 1990s Sachs licensed Campagnolo’s Ergo control lever design and put out an 8-speed group of their own.
Had SRAM been run by some MBA with a background in accounting and no history in cycling, I can guarantee you that SRAM’s first component group would simply have re-badged the old Sachs designs after the company’s lawyers negotiated an ad-infinitum agreement with Campagnolo for its existing lever design. But that wasn’t the case. SRAM, like a great many bike companies, has the good fortune to be run by a bunch of minds at their best when discussing bicycles. Even though the Sachs name no longer appears in SRAM’s family of brands, the acquisition was it’s first genius stroke. It gave the small company a portfolio of existing designs and the opportunity to build a state-of-the-art manufacturing facility in Schweinfurt, Germany. It was all the leg up they needed.
SRAM deserves some credit for spec’ing ceramic bearings to remove drag from the drivetrain.
When word began to circulate that SRAM would come out with its first full road group, we all wondered just how it would shift. Early reports were that they hadn’t licensed a design from either Shimano or Campagnolo, which meant they had a genius team of patent attorneys, less for what they filed than what they avoided. They’d danced through a minefield and arrived at the other side, feet intact. Certainly there was going to be ample time for Shimano to disassemble a shifter and file a suit, but by the time you’ve gone into full-scale production on an integrated control lever you’ve vetted the design pretty carefully.
This is the orginal DoubleTap prototype.
Let me back up a second. It used to be that the rear derailleur was the lead guitar of any component group. Why? It was the crux move, the soufflé a l’orange that makes the meal. If your soufflé falls, the meal is a miss. The rear derailleur was the engineering triumph of a group. Designed well the slant parallelogram would require the same amount of lever throw as well as an equal amount of overshift to execute a shift from one cog to the next. Done poorly, your shift from the 13t cog to the 15 was different than your shift from the 21t cog to the 23. With the rear derailleur very well understood at this point, the challenge has shifted to the integrated control lever. Witness Vision Components. While I love the work of the folks at FSA, the fact that their one full component group is triathlon-based and uses bar cons is all the evidence we need to prove the argument. Until you have introduced an integrated control lever claiming you produce a road group is a bit like saying you can see Russia from Alaska. It’s a stretch.
This shows the two pawls and single ratchet that constitute the heart of the DoubleTap system.
Even if you’ve tried a SRAM road group and didn’t like the company’s work, they deserve a measure of respect just because of the challenge the company had to meet to deliver a fresh shifting system to market. And that tag line, “Will you make the leap?” It wasn’t just some cutesy line. At the heart of that question is actual technology. Double-Tap shifting relies on an innovative (pronounced patent pending) ratchet system that causes one pawl to float over the other depending on how far the lever is depressed.
A look inside the finished lever.
Best Features: My first, favorite feature of Red, indeed of any SRAM road group, is the engineering that goes into their components. In any engineering problem you always begin with your givens, that is, your lines in the sand. Ride any SRAM group and brake response remains incredibly consistent, more consistent than Campagnolo, which is far more consistent than Shimano. Switch Shimano groups and you might as well relearn cycling. God forbid you should mix Dura-Ace levers with Ultegra brakes. The differing mechanical advantages of the two levers result in vastly sub-par brake performance. Red brake performance is like Force brake performance is like Rival is like Apex. While this is a bit off the track of an evaluation of Red as a group, give this another line or two. The point here is that SRAM established what they believed brake performance should be. It’s a firm line in the sand. No matter who you are, no matter what you spend, you deserve a certain level of brake performance, and it’s not inferior to what the pros get. Contrast that with Shimano. Ultegra is grabbier than Dura-Ace. How come? Better yet, why has brake performance for Sora and Tiagra always been so inferior to Dura-Ace? Do people on a budget have a reduced need to stop?
I really like that what you get with Apex is the same braking experience as Red; it’s just heavier.
There’s an angular elegance to SRAM’s brakes, not to mention a good reason why they all look similar.
SRAM shifters also benefit from two unique-to-SRAM design concepts. The shifters employ a technology called Exact Actuation. That means that there is no multiplier on cable travel. In broad strokes it means that if you move the shifter enough to move the cable 1mm, the derailleur moves 1mm as well. It makes drivetrain setup quick and easy and results in a less finicky drivetrain overall. And while I know plenty of riders who will swear there is nothing ever finicky about Shimano drivetrains, I’ve experienced it first-hand.
The next unique-to-SRAM design concept that I like is its ZeroLoss shifting. That we tolerate shift levers that can move a centimeter or more without accomplishing a shift boggles my mind. ZeroLoss means that if the shift lever is moving then the cable is moving, and if the cable is moving, then the derailleur is moving—you’re shifting. The kicker here is that it’s really not a particularly innovative concept. We would never, ever tolerate play in our brake levers. Extra throw? Sure, but you pull on the brake lever and that brake is moving. So why do we put up with lever movement that does less to move a shifter cable than turning the pedals? SRAM shouldn’t be occupying this territory alone, but they are, so they deserve some credit. Compare: A SRAM upshift requires less than 1cm of lever movement to execute; a downshift requires 2.5cm of lever movement to execute. Bear in mind, that’s a completed shift. A Campagnolo rear downshift lever moves 2cm before you engage the cable. The buttons move 1cm. A Shimano rear downshift lever moves 1.5cm, the rear upshift lever moves 2.5cm.
Practically speaking, what this means is that you’ve executed an upshift with any of SRAM’s levers by the time you’ve even begun a downshift with a competing system. You’ve executed a downshift with SRAM before you can execute an upshift with Shimano. There’s no adequate defense for that design flaw, weirder still that neither Shimano nor Campagnolo has addressed it so far.
I get a lot of questions about whether DoubleTap levers are confusing to operate. My answer has always been no. The reason why has to do with the play in Shimano and Campagnolo shift levers. The upshift with SRAM requires so little lever movement that a downshift never feels unnatural. You can execute a downshift with SRAM in less throw than you can complete any shift with Shimano. Only upshifts with Campagnolo come close to matching the efficiency of SRAM shifters.
Generally speaking, I don’t consider DoubleTap a selling point; it’s just not a liability. However, the fact that you can tuck the shift lever beneath your index finger and execute an upshift with far greater ease than you can with Shimano and to a more foolproof degree than you can with Campagnolo does make it a terrific system for someone with a long sprint.
You want to know what I just love? How the brake lever throw can be adjusted with just a 3mm Allen and by peeling back the lever hoods. That it doesn’t require the removal of the lever face plate nor result in that slack-jawed appearance you get with Dura-Ace demonstrates just how forward-thinking SRAM’s engineers are.
My other favorite feature of SRAM component groups (because it’s true of them all) is the PowerLock chain connector. It’s easy to connect and surprisingly easy to take apart, making chain cleaning something you can do with a minimum of fuss.
The high and low set screws are easy to get to and clearly marked. Why can’t everyone do that?
Worst Features: That aforementioned PowerLock chain connector? It’s strictly single-serve. Not wild about that. Maybe I’d feel different if I had a dozen of them tucked in a spare parts bin, but I don’t.
For a company that seems to take input from almost any source, I’m stunned and disappointed that SRAM only offers four cassettes for Red. Four. Hell, they offer six different chainring combinations for the Red crankset—12 if you count the two different spindles. Worse, all of the cassettes begin with an 11t cog. They do offer a greater array of choices at the Force level, but it seems to me that very few Red users will ever need an 11. I really hate that I can’t get a Red cassette that begins with a 12. Hate hate hate.
There are more svelte levers on the market, but the Red lever’s contours are smooth.
The shape of the SRAM lever body isn’t terrific. It’s not the end of the world as some users have complained, but the shifter body is a bit wide and a touch tall. I’ve not had a problem with the meek bump at the end of the lever, but I often hear riders complain that they fear their hands will run off the end of the lever. Just what event might cause that worries me more than the lever does, though.
The other aspect of the Red group that doesn’t pass muster is the titanium-caged front derailleur. I still like it better than Campagnolo’s carbon fiber outer plate front unit, but that’s a bit like saying you prefer malaria to meningitis.
If there’s one point of general agreement regarding Red, it’s that the front derailleur offers mushy shifting due to the titanium cage.
Assembly and Maintenance: The first time I assembled a SRAM group from scratch I was amazed at how easy it was to do. That first group was mostly Red with an Apex rear derailleur and cassette so I could run some really low gearing in the Alps, so technically, it wasn’t a full Red group, but my sense of working on other SRAM components is that a Red rear derailleur and cassette wouldn’t have altered the assembly in any appreciable way.
The one knock I have against maintenance is that if you need to replace a derailleur cable you absolutely must use a brand new cable with a soldered end. Better if you use a new Gore cable, of course. And it helps to put a slight bend in the cable about an inch from the end.
Once together it won’t need anything other than chain lube for at least 1000 miles. The only reason I know about the challenge of replacing a cable is because I moved the group between bikes. I’ve put 2000 miles on a chain and not found any appreciable chain wear.
