'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.

"More capable… easier to ride on fast on unpaved surfaces"
"As with other bikes with similarly long front ends, the revamped Checkpoint is easier and more confidence-inspiring to ride off-road on even moderately steep or loose terrain than before."

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.
The damped, controlled rebound of the IsoSpeed decoupler soaks up fatiguing bumps without bouncing you around.
