Trek's Checkpoint+ SL Gravel Bike Boasts Several Unique Features
Colin Smith — October 3, 2025
The Checkpoint+ SL is Trek’s electric gravel bike offered in three spec tiers, the SL 5, SL 6 AXS, and SL 7 AXS, built on an ultra‑light carbon frame and equipped with a TQ HPR60 mid‑drive motor, an internal 360 Wh battery, and capacities for tires up to 50 mm; weights for the ML size range around 30–31 lb and the model lineup includes variations in drivetrains, wheels, and fork travel across trim levels.
The bike is configured for mixed‑surface riding with features such as tubeless‑ready 700x42c tires (stock), compatibility with Class 3 speeds on certain trims, and higher‑end options like a 13‑speed SRAM Force AXS group and a RockShox Rudy XPLR fork on the top SL 7 AXS spec, with pricing and equipment scaled across the three versions to address different rider preferences and use cases.
