Note: To ensure that every component on your bicycle is working properly, Dan's Comp recommends that all bikes be assembled by a qualified mechanic. Improper assembly of your bicycle may lead to premature wear or failure of individual components such as headsets, crank assembly and wheels. Failure to do so may void the manufacturer warranty.
