I recently purchased a 2007 Specialized Roubaix Elite (FACT R6 carbon frame) and have come to realize that the frame is flexing quite a bit, much more than I expected. Oh btw, I'm 6"1 and 205 pounds - a mini-clyde.
I noticed that if I start pushing it on flats at aroud 20-22 mph, the front end wobbles - makes it hard to keep straight - and the back end wobbles too.
Also noticed that on descents, say 30 mph, I have to engage the brakes because the frames wobbles so much it becomes almost uncontrollable. I checked and everything seems tight; the lbs will be looking at it this weekend.
Would like your opinions if you have the same issues with Roubaix products, and if you believe a Cannondable Synapse Carbon - same product range - would be a stiffer ride.
Thanks in advance
PS. I did do a search and found some threads but nothing conclusive about weight-specific riding for these models.
