Taking its name from the natural sandstone freeride playground of Moab’s Bartlett Wash, the Bartlett is the perfect fork for the new breed of ultra-long-travel bikes that are bridging the gap between all-mountain and downhill.

Light enough to be at home on a long-travel all-mountain bike, but stiff and durable enough for freeride and bike park abuse, the Bartlett is in a class of its own. The dual-crown design provides space effciency over a single-crown - allowing for longer travel at shorter axle-to-crown lengths - as well as stiffness and steering precision that’s unmatched.

Features like the highly-tunable FulFill™ air-spring, low-pressure IFP damper, PSST™ pressure relief valves, and Outcast arch design carryover from the award-winning Ribbon. In addition to MRP's acclaimed Ramp Control™ technology, the Bartlett also features tunable air-spring volume by way of threaded spacers that attach to the Ramp Control™ cartridge. So it may easily be used as a secondary fork by riders heading to the bike park or using their enduro bike for DH racing, the Bartlett uses “Boost” 15x110 spacing - allowing those riders to use their existing wheels.
