LOOKING AHEAD

I had the chance to visit a composites conference in Paris a little while ago. It's always interesting to see where the science of carbon fiber is headed. The aerospace industry, for instance, has finally come around to using carbon fibre in a significant way for structural purposes (beyond military applications). We actually saw a pretty impressive presentation from the people at Dassault on how they were using composites to enhance aircraft performance and accelerate design time.

If I had to cite the one thing that struck me the most at the show, it was the emergence of thermoplastics as a promising solution. Basically, this material replaces the resin that is currently used as the medium for carbon fiber with specialized plastics. While the thermosets we currently use in making our carbon fiber bikes basically set permanently once they are cured, thermoplastics offer the benefit of being moldable post-cure (after subsequent application of appropriate heat). Other than the benefit of limitless formability, thermoplastic parts can essentially be "welded" together, eliminating the need for adhesives or wraps, leading to a more eco-friendly production. Best of all, at the end of its life-cycle, a thermoplastic bicycle frame could conceivably be re-usable, post consumption, in another form all together. Very interesting possibilities, given that the performance of the material (stiffness, weight, absorption of high frequency vibration) would basically be the same. Stay tuned.

Tony, I sent an email to your North American Sales Division (only because it was the only email available on the Contact Us page that I thought was applicable) regarding Guru being a sponsor on my web site, which is rapidly growing in popularity among cyclists and triathletes. I received a "no" answer back, so that is why I am writing you. I would appreciate it if you would simply take a look at my web site and tell me if you think it would be beneficial for Guru, and if so, I will send you a copy of the original email request for sponsorship that I sent to Guru that was denied. Thank you, Robert.

Tony, please disregard the above message. I have since been in contact again with a representative of your company and am very pleased with the results. Thank you, Robert.

I finally bought a new bike, a GURU Classic after 26 years of riding one of Jocelyn Lovell's bikes, built by Mulholland in the late 70's early 80's. I bought the GURU from a young guy I work with who rode it in the Ontario Juniors a few years back but gave up riding to pursue other interests. It is set up exactly as I would have purchased it new. Fantastic looks, construction, components, super light and stiff besdies the fact I got it at a very good price. I love this thing, and yes it turns heads too.

UP IN THE AIR

You often hear bike companies tout their advantages with regards to aerodynamics, based on self-administered tests in a wind tunnel. Have you ever noticed that the brand conducting the test always seems to be coming out on top? Is that because they are running the test or is it because they are not publishing the ones they are not winning? In any case, we don't pretend to be making the most aero bike on the planet, simply because we don't believe that this criterion, in and of itself, -- without taking into account the particular cyclist on the bike -- is as significant as some may claim. It doesn't take a rocket scientist to figure out that, in looking at the frontal profile of a bike / rider combo, it is the rider that constitutes the vast majority of potential drag. On a daily basis, we encounter triathletes and time trialists in "super-duper aero" positions (on competitive bikes), back-breaking set-ups that are totally not sustainable over the long haul of a race. Does someone out there realize that you can be a heck of a lot more aero by slotting yourself in an ideal position, one that won't have you shifting around -- and creating massive drag -- to relieve discomfort?

People often ask me "what bike should I buy". What I usually tell them is that, even if you don't buy a Guru, buy the bike that fits you best. Everything other aspect of performance, including aerodynamics, will naturally follow.

Hi Tony,

Of corse you are right regarding the overemphasis of "aero" drag numbers, but who is too blame? Unfortunately the executives in the bike industry continue to pour thousands of dollars into misleading marketing, instead of focusing on making a quality product. Can you blame the consumers for not knowing what to believe?
Thank you for staying true to the essence of cycling!

Hi Tony,
I just finished the April Edition of Triathlete Mag, it was their annual issue on all aspects of cylcing. . . . except there were no pages dedicated bike fit and where one might get this properly done (oh wait I did read the words "fully custom" on page 110). But there was a heck of a lot of talk about fashion, trends and aeroeverything. I approach my training in a similar manner that your company creates bikes; I am a young aspiring triathlete and when people around me start talking bike tech talk my only answer is - I am still working on my engine. I may be relatively new to the sport, but I listen and learn fast and one thing is certain, my next bike will be a GURU - can't wait!
