'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.

 

 

"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."

 

'One of the best gravel bikes I’ve been on'

'Overall, the new Checkpoint is a wonderful gravel bike. It’s faster, handles better and is more suited to the needs of today’s gravel ri

"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."

"Progressive geometry and frame storage"

"Trek has revamped its Checkpoint line-up, with the updated gravel bike coming in not one but three different flavours, catering for the needs of go-fast racers, rough-and-ready adventurers and riders looking for a versatile N+1."

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
