51 SPEEDSHOP is a collective of industry leading bike fitters, performance analysts, and athletes.  We have a combined 20+ years of fitting, teaching, coaching and generally helping people be better on their bicycle.  When you work with something every day, as we do with bikes and their components, you start to figure out what works and what does not.  From the perspective of the athlete, as well as the mechanic and the fitter.  

Our Speed Theorem line of products are the cumulative understanding of what we believe to be the very best performing line of bicycle components on the planet.  Comfort, power and aerodynamics is what we strive for when fitting athletes to their bikes. These principles are also what we design around in our products.  Invisible to the wind, seamless with the athlete and bulletproof strong when you need them to perform.
