"An excellent gravel race bike"
"Trek's new Checkpoint SLR 9 eTap is an excellent gravel race bike, built with features and geometry that calm rough surfaces without the handling feeling vague or sluggish. After two months on it, I can say that the bike we named the 2021 VeloNews Bike of the Year has only gotten better."

4.5/5
"What Trek gets right with the Checkpoint is the handling, the comfort, the storage options, and the flexibility to alter the cockpit or the drivetrain. The attention to detail...is welcome and warranted for a top-end machine."

New progressive geometry
For quick, nimble handling that still keeps you stable and in control on rougher descents.
Tire clearance
Lots of clearance means you can run meatier tires (700x45mm or 27.5x2.1") for tackling chunkier gravel and terrain.
Tons of mounts
Integrated frame bag and fender mounts make it easy to carry gear and water.
Don’t forget your pedals
This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style.
300 Series Alpha Aluminum
Trek’s premium-grade aluminum is hydroformed into size-specific tubes that provide the perfect balance of stiffness and weight.
