'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 got 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.
Tyre clearance
Lots of clearance means you can run meatier tyres (700x45 mm or 27.5x2.1") for tackling chunkier gravel and terrain.
Tons of mounts
Integrated frame bag and mudguard mounts make it easy to carry gear and water.
Sleek internal storage
A built-in storage compartment in the downtube lets you stow tools and gear.
IsoSpeed smooth
The damped, controlled rebound of the IsoSpeed decoupler soaks up fatiguing bumps without bouncing you around.
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.
500 Series OCLV
500 Series OCLV achieves a superb balance of light weight, strength, and stiffness that's perfectly suited to the sophisticated frame technologies that distinguish Trek frames.
Learn moreBlendr-compatible stem
Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.
Tubeless Ready rims
Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for road wheels. When you go tubeless with TLR, you can run lower tyre pressure for increased traction and comfort without the threat of pinch flats.
Carbon Armor
Sometimes you need a little extra protection, so we developed our light, tough external Carbon Armor polymer shield. It provides reassurance when you know your down tube is bound to take some abuse.
Gravel Specific Tyres
Wider gravel-specific tyres provide better traction and more stability while riding on gravel or dirt tracks.
Flat Mount disc brakes
All-new Flat Mount disc brakes are more elegant, lighter, smaller and cleaner than traditional disc brakes, providing superior performance and stopping power under harsh conditions.
