Ride-it-all suspension

55mm rear travel and a new 60mm Rudy XL suspension fork designed in collaboration with RockShox help smooth out rough gravel roads and let you venture onto singletrack with more comfort and capability than a rigid gravel bike.

The ultimate off-road drop bar

A new GR CheckOUT gravel drop bar has multiple hand positionings for more comfort and efficiencey wherever your ride takes you. Settle into narrow tops for more speed on champagne gravel or reach for the extra wide drops for total control on the rough stuff.

The science of full suspension gravel

CheckOUT's full suspension setup is proven to decrease fatigue and increase comfort and control when compared to its rigid counterparts, leading to a 7.3% reduction in rider ventilation, a 41.5% reduction in fatiguing vibrational energy, and 23% less steering variation. 

Big ol' tire clearance

Room for tires up to 56mm/2.2″ wide lets you tackle the rough stuff with confidence.

Geometry designed to keep you in control

Get more stability and comfort on multi-surface, multi-day adventures with an all-new Gravel Adventure geometry designed with a longer reach and higher stack.

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 lets you position your bottles and gear exactly where you want 'em in the frame.*Sizes ML and up
