'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.
