Trek Checkpoint SL Gen 3
2025 · 700c wheels · 6 sizes
Third generation of Trek's 500 Series OCLV carbon gravel frame, shared across the Checkpoint SL builds. Clearance is up to 50 mm tyres. Trek quotes both a seat tube angle and a slacker effective seat angle; its published effective top tube lines up with the plain seat tube angle rather than the effective one. All sizes run 700c wheels.
