The TTiR Custom is our vision of the perfect frameset to be used against the clock. Whether you are a time-trialist, duathlete, triathlete or track racer, there is no faster bike available. All TTiR Custom's feature custom geometry and carbon fiber lay-up optimized for each individual athlete. Using some of the cleanest low-speed NACA sections, the TTiR fuses Bob's experience in racing boats creating slippery sections with nearly a decade's worth of experience building the most desirable custom carbon fiber road frames.

Exclusively available with full custom geometry and carbon lay-up, the TTiR Custom features the same smooth ride and efficient drive train as all Parlee frames, yet allows mm by mm customization of the frame to match each riders unique positional requirements. Updated for compatibility with BB30 (Press Fit) and available with internally routed Di2 wiring.

Track version also now available.
