Procaliber 8 is a fast, capable cross-country hardtail built to chase singletrack PRs and line up for race day. Its Alpha Platinum Aluminum frame delivers confident handling through tight corners and rough sections, while a 120mm RockShox Recon Gold fork smooths out the trail ahead. A wide-range SRAM Eagle 12-speed drivetrain, lightweight Bontrager Kovee wheels, and Shimano hydraulic disc brakes round out a build that’s ready to push the pace.

Technology

A better way to produce aluminium - Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike we make – this one included – had made the switch, driving a major drop in our footprint. window.appB

By October 2025, nearly every alloy bike we make – this one included – had made the switch, driving a major drop in our footprint.\nSpecification\n\nFrame\nAlpha Platinum Aluminium, tapered head tube, internal routing, BSA 73, hidden rack and kickstand mounts, UDH, Boost148, 12 mm thru axle\n\n\nFrame Material\nALUMINIUM\n\n\nRim Size\n29\n\n\nFork\nRockShox\n\n\nFork\nRockShox Judy Silver, Solo Air spring, TurnKey lockout, tapered steerer, 42mm offset, Boost110, 15 mm Maxle Stealth, 120 mm travel RockShox Judy Silver, Solo Air spring, TurnKey lockout, tapered steerer, 42mm offset\n\n\nTires\nBontrager Sainte-Anne Pro XR, Tubeless Ready, dual compound, aramid bead, 60 tpi, 29x2.40\"\n\n\nHub Front\nShimano TC500 alloy, CentreLock, 110x15 mm thru axle\n\n\nHub Rear\nShimano TC500 alloy, CentreLock, 148x12 mm thru axle\n\n\nRims\nBontrager Kovee, double-wall, Tubeless-Ready, 28-hole, 23 mm width, Presta valve\n\n\nShifter\nShimano\n\n\nDerailleur Rear\nShimano Deore M6200, long cage\n\n\nCrank\nShimano MT520, 32T, 55 mm chainline, 170 mm length\n\n\nBottom Bracket\nShimano BB-MT501 BSA\n\n\nCassette\nShimano M6200, 10-51, 12-speed\n\n\nChain\nShimano Deore M6100, 12-speed\n\n\nBrake Rotor\nShimano RT10, CenterLock, 180 mm \/\/ Shimano RT10, CenterLock, 160 mm\n\n\nPedals\nVP-536 nylon platform\n\n\nSaddle\nVerse Short, steel rails, 145 mm width\n\n\nSeatpost\nTranzX JD-YSI34, 150 mm travel, internal routing, 31.6 mm, 456 mm length\n\n\nHandlebar\nBontrager alloy, 31.8 mm, 15 mm rise, 750 mm width\n\n\nStem\nBontrager Comp, 31.8 mm, Blendr compatible, 7-degree, 70 mm length\n\n\nHeadset\nSemi-integrated, loose ball bearing, 1-1\/8\" top, 1.5\" bottom\n\n\nGrips\nTrek Line Comp, lock-on\n\n\nSize Chart Rider Height\nRider Height -
