"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."
Read more"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."
