"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."

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 tire 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 Tires
Wider gravel-specific tires 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.

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.
