I purchased a Felt Z-70 back in May of '09. This is the relaxed frame geometry and the bike has carbon fiber forks and seat stays. At the time I weighed around 185-190, but due to some health and injury problems I'm up to about the 230+ lbs range. I've read that the carbon fiber is designed for riders under 200 lbs and I'm worried being around 35+ lbs over that when fully dressed and with equipment, is there a chance I could break the seat stays especially, or possibly the fork? I have an old aluminum frame mountain bike I can ride until I get back under 200, but would prefer to ride my regular road bike when they get my problems fixed, so thought I'd see what you folks know? The roads I ride on are basically flat and smooth and at this time my speed is about 12+ MPH when I'm able to ride.
Thanks in advance
