The Alpine Trail XR is unapologetically the best. RockShox's Zeb Ultimate fork and Vivid Air Ultimate shock are the gold standard in enduro suspension – deeply adjustable, supremely composed and built to perform at the highest level. Together they're fettled for our 160mm travel MultiTrac LT suspension platform, unlocking the upper echelons of suspension feel and dynamics.

The Horst-link design balances progression, support and suppleness. Whether you're railing berms, hunting for traction or just sending it to flat, the design's neutral predictability has your back.

Shimano's Di2 wireless drivetrain delivers instant, precise shifts under load with zero cable drama. SRAM Maven Silver four-piston brakes with 200mm HSC rotors defy physics with epic stopping power. We've fitted Schwalbe’s groundbreaking Radial tires – Magic Mary sits up front and there’s an Albert out back. Traction and puncture protection are perfectly balanced for the longest rides. PNW's Loam dropper post with Range lever and Range handlebar are the premium touch this bike deserves. DT Swiss 370 hubs laced to M502 rims make for a wheelset built to last.

It's the best Series 4 Aluminum frame we've ever made – built to go hard with optimized tube shapes, a redesigned rocker link and carefully engineered chainstays make it epically capable. Weather-sealed internal cable routing, SRAM's UDH, Boost axle spacing and ride-hushing chain slap protection are the premium touches your rides deserve. Integrated Bear Box downtube storage keeps trail essentials close without overloading your bag.

Mixed wheels – 29in up front, 27.5in out back – beautifully combine stability and agility, or run full 29in for the ultimate charger. Lock in your personal set-up with tunable geometry. Swap out the upper headset cup for ±0.75 degrees of adjustment – go slack for fast descents or steepen it up for tight tech. Chainstay flip chips adjust bottom bracket height and chainstay length. Your sweet spot is just a few adjustments away – the Alpine Trail XR is your fantasy rig, fully realized.
