Yeti Cycles SB165 T3 X0 Transmission

The mullet configuration pairs a 29-inch front wheel with a 27.5-inch rear wheel to give you the best of both worlds. The larger front wheel rolls over obstacles and maintains momentum, while the smaller rear wheel increases agility, making it easier to flick the bike through tight corners and steep, technical sections.

While the SB165 is built for aggressive enduro and gravity riding, it is surprisingly capable on climbs thanks to the efficient Switch Infinity suspension platform. However, it is optimized for descending; if your local trails are mostly flat or rolling, you might find a shorter-travel bike more efficient.

The T3 build is Yeti's top-tier spec, featuring their premium TURQ carbon fiber frame. It comes equipped with high-end Fox Factory suspension components and the SRAM X0 Transmission AXS, which provides precise, wireless electronic shifting even under heavy pedaling loads.

The 165mm of travel is designed with a linear progression curve, which means it feels very supple over small bumps for traction but ramps up enough to prevent harsh bottom-outs on big hits. It is tuned to feel planted and controlled when you are pushing hard through rough, steep terrain.

The SRAM X0 Transmission AXS is very reliable and requires less maintenance than traditional cable-actuated systems because there are no cables to stretch or housing to replace. You will simply need to keep the AXS battery charged and ensure the derailleur hanger is properly aligned, which is straightforward with this system.

Yes, the bike features a threaded bottom bracket, which is generally easier to service and less prone to creaking than press-fit alternatives. This makes routine maintenance and component swaps much more straightforward for the home mechanic.
