Dorel, the parent company behind Cannondale, Schwinn, GT, Mongoose, Iron Horse and Sugoi purchased the Canadian brand Guru last year. In doing so, Dorel was able to bring into the fold a new fitting system based around what might be the most sophisticated fitting device on the market, the Guru Dynamic Fit Unit. We got a look at the Dynamic Fit Unit at Interbike and had a chance to see the basic process for taking someone through a fit.
During the Cannondale team introduction I had a chance to go through a fitting with Colby Marple from Guru. The Guru system offers two different levels of fit, one for production bikes and another should you want to have a custom bike (say a Guru) produced to your personal requirements.
The fitting began with me being scanned by a Kinect unit. Yes, Kinect as in Xbox. As it turns out, Guru’s lead software developer was one of the original developers working on the Kinect unit. The Guru software includes a database of production bikes and their geometry. Based on its scan of me, we were able to choose a couple of different bike models and it quickly showed how neatly I fall between the 56 and 58 sizes.
The Dynamic Fit Unit (DFU) is the real heart of the system. Quick release clamps allow for easy swapping of both saddles and handlebars and the cranks can be adjusted to provide riders the recommended crank length.
For those familiar with the latest version of the Serotta Size Cycle, one of its big selling points is the ability to use an electric driver to make handlebar and saddle position adjustments while the rider pedals. The ability to move smoothly through a range of possible reaches, bar heights and saddle heights is one of the two biggest advancements in fit methodology of the last 25 years, the other being the rider flexibility assessment. I had one of the original Serotta Size Cycles in my garage for about a year and I’d use it to experiment with my fit. The difference between getting off the bike, making an adjustment and getting back on vs. pedaling continuously while the bar or saddle moves is the difference between the Dewey Decimal System and the Internet. It’s just no comparison.
Where the Guru DFU differs with the Serotta Size Cycle is that servo motors in the DFU unit make precise adjustments based on keyboard inputs by the fit tech, resulting in changes of higher precision and performed at greater speed. But that’s not all. Supposing you like your bar position relative to your saddle height but you want your saddle to go up a centimeter. The DFU fitter can make the two changes simultaneously. Similarly, say you want to try a slightly steeper seat tube angle, the DFU can simultaneously raise your saddle and bring it forward while also dropping the bar and moving it forward in order to preserve the saddle-to-bar relationship.
Wait, that’s not all.
The full-on Ginsu pitch is that the fitter can rock the full position back to simulate climbing on almost any gradient in order to allow you to experience what that position will feel like on Mt. Shootmenow. And if you’re getting a mountain bike fit, you can be swung forward to simulate an ultra-steep descent to get a feel for just how much weight you’ll have on the bike’s front wheel.
My view is that a fit system is just a tool. From the gear to the methodology, a fit system is just a tool to do a job. In the hands of someone with minimal training, it might not be a very effective tool. However, in the hands of someone like Cyclologic’s Paraic McGlynn or Bike Effect’s Steve Carre, the DFU is the most powerful dynamic fitting tool I’ve encountered. This thing could make a great fitter as formidable as Peter Sagan is in a sprint.
My session resulted in a fit that I’d be willing to put my faith in. It differs from my current fit by less than a centimeter in saddle height, while the bar position was more than a centimeter higher with roughly the same reach. I should mention here that because I move between a number of bikes on an ongoing basis and between as many saddles, I’ve grown immune to small differences in ft. I had to learn to put up with changes in my fit from bike to bike, even when I’ve gone to great lengths to replicate my position exactly. Exactly just never happens. Because I’ve managed to ride well on a number of bikes with slightly differing fits, I’ve come to believe that when someone (be it fitter or rider) starts to get fussy about that last millimeter they are failing to understand the inherent adaptability of the body. And I write this with the knowing admission that I’ve suffered problems at the hands of bad fits by alleged fit experts.
I think part of the genius of the DFU is that all the rider has to go on is the feel of the fit. With no stem to look at nor the visual cue of seeing the drop from the saddle to the bar framed by the bike itself, all you can really go on is the feel of sitting in the saddle and reaching for the bar. When the original Serotta Size Cycle was introduced I was skeptical that a good fit could be achieved by a fitter simply listening to feedback from the rider. I was perhaps right to be suspicious of the original iteration, but today it’s an approach that makes terrific sense. It does require that the person being fitted talk a lot about what he or she is experiencing as the key to a good fit is communication, but even a relatively quiet person can get a great fit from a good fitter. The best can see unwanted muscle tension the way poker players can suss out tells.
Finally, I’ll grant that it might be a challenge to place your faith in this approach until you’ve experienced it. I learned to give a lot of feedback as either the bar or saddle is moving: no, no, no, not bad, okay, yes, yes, errmm, nah, no, no, no. It was interesting to me that Colby had the same reaction to my feedback that Steve Carre at Bike Effect did. They both noted that they saw an easing of tension in my shoulders just as I started to say “yes.”
Again, the Guru system is just a tool, and that goes double for the DFU. However, in the hands of a great fitter I think the DFU has the ability to help a fitter arrive at a result that the client will believe in. Why? Well the dirty little secret of fitting is that the single biggest challenge a fitter faces is getting the client to not just adopt the recommendations, but to stick with them long term rather than switching the bike back after a ride or two. The DFU provides an experience that makes the recommendation one’s own, not some outside piece of advice. When I was first trained as a fitter, recommendations were made based on a set of tables the correlated to the rider’s personal dimensions. The process was effectly: here’s what you are, so here’s what your fit should be.
The DFU, more than any other fitting tool I’ve encountered, upends that convention by making the fitting a matter of self-selected comfort. That might seem obvious to the point of naive, but really a proper fit is fundamentally a function of comfort and who can better know your comfort than you?
Mavic is back in the pedal game. Yes, I know it looks like a Time pedal. They make it under contract for Mavic. Unlike previous Mavic pedals, this one weighs less than a bunch of grapes and has more cornering clearance than a little boy’s hips.
Guru has introduced a new frame, the Photon HL. While a great many manufacturers lead with frame weight, Guru has something a bit different. The Photon HL comes in custom geometry. Only custom geometry.
The layup work belongs to an emerging cohort of carbon builders—it’s an exceedingly short list; the only other ones I’ve seen so far are Alchemy and Argonaut. The frame is bejeweled with tiny pieces of carbon that speak to layup work that isn’t just deliberate, it’s artful.
For me, this frame was the single biggest revelation of the show.
Enve introduced some new budget-oriented builds for the 25s, 45s and 65s. They sourced different spokes and hubs without changing the rims in order to bring the cost down.
Enve also introduced a new set of disc brake hubs that are now an option for the SES series wheels.
Currently, there aren’t that many options for aerodynamic carbon wheels with disc brakes, but then maybe that’s because the demand for them isn’t quite what it is for carbon fiber frames.
Moots introduced a new model, the rather aptly named Vamoots Disc Road. It’s a gravel grinder that was gifted great tire clearance and disc brakes.
It’s spec’d with an Enve fork with a steerer that tapers from 1 1/8″ to 1 1/2″ for great strength and precise steering.
The folks at Moots made a battery holder for the Di2 battery to place it inside the seatpost. The build used a Dura-Ace Di2 group combined with Shimano’s new road disc brakes. One of my favorite bikes of the show.
If all you ever do is write about road bikes, you miss out on stuff like this cruiser from Electra. It’s as much a fashion statement as it is transportation, but it’s a fun chance to point out that we, as dedicated cyclists, can incorporate a city bike into our lives for running errands and it can make a fun and entertaining statement at the same time.
When I was a kid I wanted to replace the grips on my Raleigh Chopper with some cool ones that sparkled. These orange ones from Electra would have been ideal. They speak to the many accessories that Electra produces that not only look good but often trade on a bit of nostalgia, and while I’m not a big fan of nostalgia, this is one time when it’s not just harmless, it’s fun.
The Electra electric Townie goes for less than many road bikes. At $2200, it’s not cheap, but this bike, and others of its ilk, is probably our best shot at recruiting more people into cycling. As the roads become ever more clogged with cars, we need all the sympathy and allies we can find. Electric bikes may be our best shot at making more friends.
The Townie comes with a dynamo front hub that powers a headlight. Nifty feature.
Focus unleashed a new road bike, the Izalco Max. This new bike is less a revision of the Izalco than a whole new bike. They’ve trimmed the tube shapes to just the structural essentials. It’s interesting that as bike engineers become more knowledgeable about bike design certain elements become more and more consistent, such as tiny seatstays, round top and down tubes and tapered forks.
This bike may look a bit familiar. Gone are any unusual tube shapes and the seatstays have been shrunken to not much more than the thickness of a pinky for good reason; those tiny stays do make the ride more comfortable.
What did surprise me about the new Izalco Max was just how tiny the fork blades were. My first guess would be that this fork would be comfortable but not handle well, but I’m told it has the precise steering we’ve come to expect from bikes ridden at the WorldTour level.
I’m in Park City, Utah, attending Press Camp, an event organized by Lifeboat Events. One of the partners in Lifeboat Events is Lance Camisasca, the former director of the Interbike trade show. Press Camp is a trade event for bike companies to get serious face time with the media. Sessions are broken into 45-minute blocks, of which I routinely ran over, but we’ll get to that.
That Camisasca is the former director of Interbike probably says something about where he thinks the industry is headed and whether or not he thinks there’s a problem with Interbike’s business model. As a means to reach the media, in only one day here, I have to say that I think it is entirely more effective. I was able to have real conversations with people in the industry, some of whom I previously knew, some of whom I didn’t, and discuss their product line in some depth without having someone interrupt us to ask for some stickers.
The funny thing about the increased time allotted for meetings is that I still never seemed to get through anyone’s full product line. For me, most of my mission was to identify products that I would be interested in reviewing at a later time.
I really welcomed the opportunity to meet the team behind NeilPryde bikes. The Bura SL, shown above, was really impressive. If the numbers I saw are accurate, it has one of the highest stiffness-to-weight ratios of any bike on the market. While they are doing a number of interesting bikes, this one was particularly interesting.
This frame features an asymmetric seat tube design without sacrificing any BB stiffness. And while all the engineering that goes into their frames appears to be very well done, I didn’t expect a brand new to cycling such as NeilPryde to have the ability to surprise me with weight and stiffness numbers that rival those from companies like Cervelo and Cannondale.
Stan’s NoTubes has moved into wheel production and these three rims show the evolution of one of their rims. Material was added at the spoke bed (center and left) as well as at the bottom of the brake track to increase lateral stiffness.
Of the many products out there I get requests for, perhaps the single most frequent category I’ve heard about in the last six months to a year is road tubeless. We’ll be rectifying that omission in the near future. I’ll make sure to ride some tubeless-specific wheels as well as convert some ordinary wheels to tubeless. Should be fun.
Guru seems to be best known for the carbon fiber bikes. What you may not know is that they started with TIG-welded steel bikes and then moved into titanium and aluminum before moving into Scandium. No matter what frame material you’re interested in, their delivery time is stunning. Few companies can offer a bike in less than a month, and Guru is delivering.
Guru has been on my radar for some time. I’ve been aware of the brand and some of their successes in racing, particularly in triathlon. That said, I’d never seen one of their titanium bikes up close. We’re discussing a review of one of their bikes and I’m almost embarrassed to admit that I’m as interested in their titanium bikes as I am their carbon fiber ones. That just doesn’t happen.
This helmet by Kali Protectives can be used either for cross country or the road; the visor is removable. What was most interesting about Kali’s helmets was that they are using a much lower density foam closest to the head. By using lower density foam more energy is dissipated before the head feels any impact. To use the lower density foam the vent holes have to be smaller and less frequent, but in the event of a crash that results in head impact, you could be substantially less traumatized.
I’ve been itching to get a chance to discuss Enve’s new Smart System rims and wheels. I’m currently finishing up a short-term review of a pair of wheels built with the 34 rims. And they were nice. The wheels that Enve’s Jason Schier and Simon Smart most wanted to discuss were the 67 (BTW: don’t say “sixty-seven,” say six-seven”). This is the mid-depth of the three wheels and it’s the one where they claim the greatest benefit of the new rims comes into play. Stay tuned.
