Why We Like The Yeti SB165 Turq Mountain Bike Frame

Yeti saved the best for last and is back with updates on their long-travel slayer, the SB165. Last in line to receive the revised switch infinity and frame clearance update, the SB165 also hosts a handful of other exciting new features. Featuring a dedicated mixed-wheel setup, a revised Switch Infinity platform, and enhanced downtube clearance and protection, the new SB165 platform brings us long-anticipated changes that we gravity-focused riders have been craving. The revised Switch Infinity system received newly designed pivots, improved seals, and better bearings for enhanced durability and strength. Yeti revised its downtube protector on the SB165 this year and went with a dual-density version that features a removable hard cap layered over a rubber inner layer for better impact protection. Additionally, the area where the downtube meets the bottom bracket has been revised to give us more clearance when sending it in chunky terrain. Due to the new 29-inch wheel up front, the SB165 is centered around a 170mm fork, dropping 10mm over the previous model to keep the geometry the same. 165mm of rear wheel travel powered by the renowned Switch Infinity suspension system ensures confidence and precision when bombing down steep trails, and climbing back up is smooth and efficient thanks to the Switch Infinity's translating pivot design and the steep 76.9-degree seat tube angle. The slack 63.5-degree head tube keeps us composed on steep terrain, the 29-inch front wheel rolls over rocks and roots more easily, and the long wheelbase ensures stability and confidence during more aggressive riding. A 27.5-inch rear wheel and short, size-specific chainstays make for a more agile and poppy bike with a tighter turning radius and more clearance over the rear wheel. The SB165 also received a revised 22-percent progression curve over its previous 27.5, giving us the super plush ride we know and love but now with more support through the mid-stoke for more capability in a greater range of terrain. Additional features on the SB165 include fully enclosed cable routing for a silent, clean-looking ride, shorter seat tubes to ensure room for long-stroke dropper posts, SRAM's Universal Derailleur Hanger for easy replacements, and integrated ISCG-05 and bash guard for protection.

*Due to a high demand in the global supply chain and bike industry since the start of the pandemic, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be of equal or better spec level.
