People think I am crazy at times. I ride my 1998 CAD3 Cannondale and don't see much difference between my current full 2014 carbon Madone 4.7. TO be honest, after 5 minutes on the bike, I would not know which bike i am riding. But my best ride was a 2009 (?) Lemond Chambery. Partial carbon.alum spine design I think it was called. I don't think it was so much the material it was made of, but the geometry and fit. I had a full alum Lemond Torumalet right before it, fit well but wimpy like a noodle. I was afraid to stand up and sprint on it as I could feel the frame flex. Sure enough after the 3rd year, the thing snapped like a twig on a climb, no standing. The Chambery was a great ride but I rode the heck out of it. I was training for a mtn ride (100 miles 10,000 ft gain) riding the Lemond. I put a big heavy old school Armadillo on it that year and put 5,000 training mile on it. Yeah, big 25c Armadillo but not one flat in 5,000 miles. I rode through the mountains, everywhere without a worry. Loved that big tire but also loved on event day when I rode GP3000's in the event. I believe that was the GP4000 at the time. But sadly, the following year I was on a climb and snap! Frame snapped at the aluminum section, not the carbon. After 2 failed alum frames, I don't worry so much with carbon. My current carbon frame how has more mileage than either one of the alum frames the snapped. Not to start a debate. Just as a clydesdale, I don't stress about the carbon frames even with all the warnings in cycling forums. Though I have not had any issues with full carbon, I am somewhat disappointed with the ride. I'm sure it was the design and geo but for me, the best riding bike I have had was the Lemond Chambery. Fit like a glove and floated like a butterfly! I miss this bike! Yup, 5,000 ft gain on training rides through the mountains with a big fat 25 Armadillo on the back, that's some good training.
