All grit. All glory.
The Checkmate SLR is a game-changing gravel race bike and our fastest and lightest gravel bike ever. Designed for performance across the board, the Checkmate shares some of the same ultra-lightweight aero features as our best road race bikes and boasts plenty of capability to take you off the beaten track and across the finish line in personal record time at gravel racing’s most epic events.
"Gravel bikes have come a long way in a short time, and the Checkmate may demonstrate that better than any bike"
“While the bike is race-rigid, its IsoSpeed […] does a good job of keeping me comfortable over persistent surface chatter"
Our lightest gravel bike ever
Half a kilo lighter than Checkpoint SLR
The Checkmate features new lightweight aero tube shapes and premium, ultra-light 800 Series OCLV Carbon to help you fly up hilly courses and shoulder your bike with ease.
*Based on aero wind tunnel data applied to simulation of Unbound course at 200W
Ultimate race DNA
The same lightweight Full System Foil aero tube shapes as the revolutionary Madone Gen 8 help make the full rider system – rider, bike and components – faster everywhere.
Positioned to win
The Checkmate’s all-new Gravel Race geometry keeps you aggressive and tucked out of the wind so you can crush your PR on race day and stay confident and in control on even the gnarliest gravel roads.
Versatile aero bar/stem
A lightweight and aero integrated one-piece bar/stem is 3 cm narrower on the hoods than in the drops so you can tuck into an aero position on the hoods to fly comfortably across the dirt or drop down low for more control in the rough.
Make pebbles feel like pavement
IsoSpeed comfort technology absorbs fatiguing bumps in the road so you can haul ass even when you’re in it for the long haul.
Traction satisfaction
Roll fast over the rough stuff with room for up to 45 mm gravel tyres (as measured).
