How do you people hit 50+ on these bikes. I've hit 39-40 on 1.10x26 slicks with 44x11 gears on a very long downhill but couldn't pedal anymore. I remember a similar thread about how gast you ride on the flat and some of the speeds people came out with meant that they rode 20% faster than Lance has ever ridden. I think you all need to check your computers.
