ASR T5 Ultimate XX Transmission Carbon Wheel Mountain Bike

What Our Gearhead® Experts Are Saying:

"This build is as high-spec as XC bikes get. The Flight Attendant system constantly optimizes pedaling efficiency, and the XX SL Transmission drivetrain is incredibly precise under load. The carbon layup feels razor sharp without being harsh, and the DT Swiss XRC wheels spin up instantly. It’s built for riders who want podium-level performance with zero compromises."

The ASR T5 Ultimate XX Transmission represents the most advanced expression of Yeti’s modern cross-country platform. Built around the TURQ Series carbon frame, this chassis utilizes custom ply shaping, precision layup schedules, and size-specific stiffness targets to eliminate redundant carbon while maintaining race-level torsional rigidity. The result is an exceptionally lightweight, responsive frame engineered to deliver consistent ride characteristics across every size. A threaded bottom bracket, 148x12mm Boost rear spacing, and integrated derailleur hanger and axle system reinforce durability without excess material.

Suspension is handled by RockShox Flight Attendant technology, pairing a 120mm SID Ultimate fork with a SID Luxe Ultimate rear shock delivering 115mm of highly usable travel. The leverage curve is tuned for near-linear progression through the mid-stroke to maximize pedaling efficiency at typical XC sag around 20%, while ramping in the final quarter of travel to maintain composure on aggressive lines and high-speed compressions.

The SRAM XX SL Eagle AXS Transmission drivetrain mounts directly via the Hangerless Interface for maximum alignment accuracy and structural strength. A 10-52T cassette provides broad gearing range, and the integrated power meter crankset supports data-driven training. DT Swiss XRC 1200 Spline 30 carbon wheels reduce rotational mass for explosive acceleration, while Maxxis Rekon and Rekon Race 2.4in tires balance traction and speed. With internal lockout routing, integrated fender, dual bottle capacity, and compatibility with long-stroke dropper posts, this bike is engineered specifically for modern XCO and marathon competition.

Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
