Overview
A bare aluminum full suspension frame for 27.5 or 29 inch wheels with 170-190mm of travel, aimed at DH, AM, FR and enduro riding. This listing is the Black 27.5 x 18 inch soft tail version with a boost thru axle.
Travel on this frame runs deeper than a typical trail chassis, 170 to 190mm, which puts it closer to a downhill-oriented build than an all-mountain one. It ships as a bare frame only, with a 34.9mm seatpost clamp, a 30.9mm post and a threaded BSA bottom bracket. The rear fork is described as thickened for extra strength on rough terrain.
- 27.5 or 29in wheels, sizes 15/16.5/18in
- 170-190mm travel for DH/AM/FR/enduro
- Boost 12x148mm thru axle, PM75mm disc mount
- Fits 230x65mm or 240x76mm rear shocks
Who it's for
Riders building a longer-travel DH, AM or enduro bike who plan to source their own shock, fork and drivetrain. Not suited to anyone who wants a lighter, shorter-travel trail frame.
Pros and cons
- 170-190mm travel suits DH, AM, FR, enduro
- Boost thru axle and threaded BSA bottom bracket
- Thickened rear fork built for rough terrain
- Full internal routing keeps cables protected
- Shock absorber not included
- Heavier frame weight, about 3850g bare
Performance notes
