"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."

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.
Sleek internal storage
Built-in storage compartment in the downtube lets you stow tools and gear.
The damped, controlled rebound of the IsoSpeed decoupler soaks up fatiguing bumps without bouncing you around.
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.

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.
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.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
