2026 Large Rocky Mountain Altitude A50

Built for riders who want confidence on steep descents, technical terrain, and demanding all-mountain trails, this enduro bike combines 160mm of rear travel with a 170mm RockShox ZEB RC fork for a capable, planted ride when the trail gets rough.

The FORM™ Alloy frame features RIDE-4™ adjustable geometry, internal cable routing, sealed cartridge bearings, a threaded bottom bracket, and ISCG05 chain guide tabs. With a 63° head angle, 77° seat angle, and up to 505mm of reach, the geometry is designed to stay stable at speed while keeping the rider positioned efficiently for long climbs.

The suspension package pairs a RockShox Super Deluxe Select+ rear shock with the ZEB RC fork, providing a balanced setup for aggressive trail and enduro riding.

A premium SRAM Transmission drivetrain gives you crisp, dependable shifting, while SRAM Maven Stealth 4-piston brakes with metal pads deliver the stopping power needed for steep and technical terrain.

The wheel and tire package is ready for serious trail riding, featuring WTB ST i30 TOUGH TCS 2.0 rims, Boost hubs, and a Maxxis tire combination of Assegai 2.5 WT up front and Minion DHR II 2.4 WT in the rear.
