Welcome to the Trek Pilot Wiki! The Pilot series from Trek bicycles debuted in 2005 and offers a compact frame geometry. Pilot frames have long reach brakes and a rear eyelet to accommodate fenders. The Pilot 5.2 offers the same OCLV carbon frame as the 5.0. Enhancements include the OCLV carbon fork and an all-Ultegra drivetrain. WSD, SPA and flat bar versions are also offered.
