Its Alpha Platinum Aluminium frame uses Trek’s high-pivot suspension design, which redirects the rear axle path rearward as the bike moves through its travel. This helps the bike stay composed over repeated bumps and square-edge hits, improving traction and reducing hang-ups at speed. The idler pulley manages chain growth, keeping the drivetrain running smoothly as the suspension moves.The frame delivers 200 mm of rear travel through a magnesium rocker link and Active Braking Pivot, which keeps the suspension working effectively even when braking hard through rough sections. Integrated frame protection and an ISCG-05 mount add durability and make it easier to run chain-guides for racing.A RockShox Boxxer with DebonAir+ spring and Rush RC damper provides 200 mm of controlled travel up front. With its stiffer chassis and downhill-ready tuning, it gives a calm, predictable feel when steering into steep chutes or pushing through corners. The matching 200 mm rear travel comes from a Marzocchi Bomber shock, offering a supportive, consistent feel on fast runs.SRAM’s GX DH 7-speed drivetrain keeps shifting simple and reliable, giving you a focused range suited to downhill racing. A Truvativ Descendant DH chainset with a 34T ring pairs with a SRAM PG-720 cassette for strong acceleration out of turns.Braking comes from SRAM Maven Bronze 4-piston hydraulic discs, offering solid power and control for technical sections and long descents. Bontrager’s Line DH 30 wheels, built for downhill strength, are paired with Bontrager G5 Team Issue 29x2.50" tyres, giving grip and support on loose, rocky and high-load terrain.Downhill-specific finishing kit—including a direct-mount Bontrager stem, wide 780 mm bars and a Rhythm Elite seatpost—rounds out a setup ready for bike-park days and race-focused riding.
