Product Details
The Moots Mountaineer YBB Frameset revives a storied name from Moots' history, dating back to one of the company's first mountain bikes, produced in 1983. This modern interpretation blends cross-country comfort with contemporary features for exceptional versatility across any terrain. Whether tackling cross-country trails, singletrack, gravel routes, or multi-day bikepacking adventures, the Mountaineer delivers confidence-inspiring performance through its unique combination of modern geometry and legendary YBB micro-suspension technology.
Built around 120mm travel fork compatibility, the frameset pairs progressive 29" geometry with Moots' renowned YBB micro-suspension soft-tail system. This design provides just enough suspension to smooth trail imperfections without sacrificing the responsive handling needed for fast, technical riding. The YBB system takes the edge off rough terrain while maintaining the efficient pedaling characteristics that define quality hardtail performance, creating a bike that excels equally on quick XC rides and extended backcountry expeditions.
At the core of the Mountaineer lies Moots' oversized seamless 3/2.5 titanium tubeset, delivering exceptional durability and stiffness across the complete size range. The thin-walled, US-made tubeset construction provides the ride quality and longevity that titanium is renowned for, ensuring this frameset will deliver reliable performance for decades. The oversized tube profiles offer optimal strength-to-weight characteristics while maintaining the compliant ride feel that makes titanium the material of choice for discerning riders.
Built for cyclists seeking a versatile platform that balances modern capability with timeless design, the Moots Mountaineer YBB Frame offers the foundation for creating the ultimate all-rounder. This is a bike that lets riders focus on the journey rather than the trail, delivering unmatched comfort and performance whether exploring local singletrack or embarking on ambitious bikepacking routes.
