Trek Checkpoint SL 5 Custom - 2025, X-Small

The 2025 Trek Checkpoint SL 5 AXS Custom is a highly capable, premium carbon gravel machine engineered to comfortably cross massive adventure boundaries, combining rapid pavement velocity with stable, loose-surface terrain composure. Meticulously tailored as a nimble Extra Small (XS / 49cm) build layout, this performance chassis features an optimized endurance geometry recommended to deliver full structural comfort for riders between 5'0" and 5'6". The frame is sculpted from Trek’s signature 500 Series OLV Carbon, integrating a concealed internal down tube storage compartment to stow ride essentials cleanly out of the wind. To smooth out taxing fire road corrugated washboards, the frame features the innovative IsoSpeed decoupling link at the seat tube junction, allowing the chassis to flex naturally under impacts to delay upper-body fatigue without sacrificing your bottom-bracket pedaling efficiency.

The technical infrastructure relies on a highly modernized, zero-compromise wireless electronic layout centered around the intuitive 1x12-speed SRAM Apex AXS electronic groupset. This streamlined setup executes crisp, instantaneous shifts at the single click of a paddle, relying on an Apex AXS XPLR rear derailleur to handle chain retention across a wide-range 11-44T cassette. Power is transferred through highly efficient, compact 165mm SRAM Apex crank arms carrying a versatile 40T SRAM X-Sync single chainring, providing an exceptional mechanical advantage to comfortably spin up loose, loose backcountry walls. Deceleration is linear and deeply reassuring, governed by Apex hydraulic disc brakes to ensure precise modulation into high-speed gravel corners.

The control deck and rolling stock on this premium Checkpoint build are carefully scaled to optimize off-road handling metrics for a smaller rider profile. Up front, steering response is exceptionally sharp and intuitive, matching a tight 60mm Bontrager Comp stem to flared 420mm Bontrager gravel bars to optimize control when descending in the drops. Out back, an ergonomic, pressure-relieving Bontrager Verse short-nose saddle provides comfortable sit-bone support over long-range adventure sectors. The bike rolls on robust Bontrager Paradigm SL alloy wheels wrapped in supple, multi-use 700x42c Bontrager Girona RSL tires. Configured with a complete, turn-key tubeless setup, this wide footprint yields incredibly low rolling resistance and superior puncture defense over rough fire roads. Arriving in great condition, completely prepped, and tuned by a master technician as shown across image_248.png through image_254.png, this showroom-ready Checkpoint needs absolutely nothing and is 100% ready for your next multi-surface rides.
