ASR T5 Ultimate XX Transmission Carbon Wheel Mountain Bike

What Our Gearhead® Experts Are Saying:

"I’ve ridden a lot of XC bikes, and this is one of the few that truly feels world-cup sharp straight out of the box. The Flight Attendant suspension keeps the chassis riding high and efficient without me thinking about lockouts, and the XX SL Transmission shifts under full gas with zero hesitation. It’s incredibly light, brutally responsive, and still composed when the course turns rough. If you want every possible advantage on race day, this is it."

When the tape drops and the course tilts skyward, we want a bike that disappears beneath us and answers every surge without hesitation. The ASR T5 Ultimate XX Transmission from Yeti is built for exactly that moment. It is the lightest full-suspension platform in their history, reborn for modern cross-country courses that demand more than lungs alone. Steep punchy climbs, off-camber roots, high-speed chutes at race pace—we ride it all with the confidence to attack.

Underneath us, the TURQ Series carbon frame sheds every gram of redundant material through custom ply shaping and size-specific stiffness tuning. A 120mm RockShox SID Ultimate Flight Attendant fork pairs with a SID Luxe Ultimate Flight Attendant shock delivering 115mm of efficient, race-tuned rear travel with a near-linear leverage curve and supportive ramp at the end stroke. SRAM XX SL Eagle AXS Transmission mounts directly via a hangerless interface for precise, load-proof shifting, while DT Swiss XRC 1200 carbon wheels and Maxxis Rekon 2.4in tires keep speed high and rolling resistance low. With modern geometry, room for two bottles, integrated fender, and dropper compatibility up to 200mm on larger sizes, this is a purpose-built weapon for today’s XCO and marathon start lines.

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.
