Out of Stock

Massive tyre clearance

Room for up to 56 mm/2.2″ tires let your customers tackle the gnarly stuff with confidence.

Confidence-inspiring geometry

The CheckOUT’s all-new Gravel Adventure geo increases stability and comfort on multi-surface, multi-day adventures.

Trail-tested
carbon frame

Your fast-and-far customers can pack heavy and still ride light with a 500 Series OCLV carbon frame tested to robust MTB standards.


The CheckOUT SL 5 is an adventure-ready full-suspension gravel bike for getting far, far out there. Its carbon frame delivers 55 mm of rear travel from a RockShox SIDluxe IsoStrut shock, while a RockShox Rudy XL fork smooths rowdy roads and trails with 60 mm of travel. It comes ready to explore with Bontrager Paradigm Comp wheels, a 12-speed Shimano GRX drivetrain and TranzX dropper post.

Built for bikepacking

Haul it all with 18* frame mounts, an integrated rear rack that works with the bike's suspension and dropper post, and Adjustable Multi-Mounts that let riders position bottles and gear exactly where
they want ‘em. *size ML and up 

The ultimate off-road drop bar

The CheckOUT is designed to be faster than a mountain bike on tarmac roads and champagne gravel thanks to a new GR CheckOUT drop bar that’s quick on the hoods and has an extra wide flare and ergonomic back sweep for more comfort and control.

****NOTE: This bike is available for purchase online, but must be picked up from an approved store.

Bike Weight: Many brands strive to list the lowest possible weight, but in reality weight can vary based on frame size, finish, hardware and accessories. The most accurate way to determine any bike's weight is to have your local showroom weigh it for you.
