Suspension is covered by Fox Performance units front and rear: a 34 SC Float fork with 110mm travel and a Float SL Performance Elite shock, both with remote lockouts for instant transitions between climbing efficiency and descending control. This suspension package ensures precise steering and smooth tracking on rough XC courses.
The Shimano XT 1x12 drivetrain delivers crisp, reliable shifting across a 10-51T cassette, giving you the range to handle steep climbs and fast straights. Matching Shimano XT hydraulic disc brakes provide strong, predictable stopping power, with 180/160mm rotors keeping things balanced for XC racing.
Rolling stock comes from Newmen Beskar 30 tubeless-ready carbon wheels, lightweight and stiff for fast acceleration. These are wrapped in Schwalbe Racing Ray and Racing Ralph Super Race tyres (2.35”), offering the ideal balance of grip, speed and durability on XC terrain.
To complete the build, the bike includes a Fox Transfer dropper post for technical descents, a Newmen Advanced carbon bar for responsive handling, and an ACID Nuance SLT X carbon saddle for lightweight comfort.
