You are the engine. ...... The most important part of a bike are the legs connected to the pedals and the spirit driving those legs. I agree with this. Some people think they can buy success. For example, the insane drive to cut weight on bikes (like double the price and go from 18# to 16#), when all we need do is diet for a week or two and lose twice as much ourselves! I'm no hammer myself, but I love to play with the minds of the trendy crowd for time to time. When I am out for a leisure cruise on my old trek 200 rail trail bike (199 new, but I did trick it out a little after I got it) and some dolled up guy goes by in a crouch at 20 mph on his new Lemond or Felt, I love to crank up at 105, shift and paceline with him. It freaks them out to see me sitting upright and staying with them, fat tires and all For road rides, I have a 1986 Trek Pro 560, that I paid 250 for (Has a mix of DA, Ultegra and Superbe). It weighs 18 # and I can keep up with anyone at least for a while on it.
