One of the guys that I ride with in cyclo-cross and mountain bike races that consistenly wins in the Masters and when he was younger was a National champion in Cyclo-cross in the United States is Dale Knapp. Dale is 44 years old and weighs over 200lbs. His legs are the size of my waist. He is a amazing to watch on the bike. He races for Kona which is not exactly known for building light weight bikes. Yet he still wins. What he has, which very few people have, is the ability to thrive off of the pain experienced during a race. And he has three other things that we can all acheive.
Stamina, Power and efficiency.
The more that I develop the stamina, power and efficiency the less I pay attention to the grams of a handlbar or seatpost.
What are some other keys to speed that do not require purchasing expensive parts?
