The staff at T3 Cycling & Triathlon knows that a bicycle's fit is crucial to performance and comfort—and so, rather than eyeball how a road or triathlon bike meshes with its prospective owner, they rely on a more precise system. Aided by the Retül system, which uses motion-capture video with 3D LED tracking to measure body angles and movements, they precision-fit customers to their own bike or to a bike make and model of their choice. Chances are they'll have that bike in-house: the store carries recreational and competition road and triathlon bikes from brands such as Felt, Guru, Quintana Roo, Cervelo, BMC, and LOOK. The house mechanics' steady hands also repair bikes during
tune-ups or can perform a complete overhaul with cable and bearing replacements.
