Crankbrothers Synthesis Alloy 2.0 DH Rear Wheel 157x12mm Downhill MTB Hub

The Crankbrothers Synthesis Alloy 2.0 DH Rear 157x12 Wheel represents a high-performance solution tailored for downhill mountain biking professionals and enthusiasts. Engineered with precision, this rear wheel features the robust Crankbrothers Ratchet 157x12mm hub, delivering exceptional reliability and engagement on the most demanding trails. Its design incorporates advanced materials and engineering enhancements that prioritise durability and consistent performance under extreme conditions.

Constructed from upgraded Alloy 6069, the Synthesis Alloy 2.0 wheel offers superior tensile and fatigue strength compared to its predecessor, Alloy 6013. This upgrade ensures enhanced resistance to stress and prolonged service life. Additionally, the shot-peened finish not only elevates the wheel’s aesthetic quality but also significantly improves its resistance to cracking and wear. The re-engineered rim profile is optimised for rear-wheel use, providing increased impact resistance and stiffness to maximise power transfer and control during aggressive downhill riding.

Designed to balance performance with reliability, the wheel’s 32-spoke configuration utilises Pillar SSB 34 spokes paired with a wide 29.5mm internal rim width, delivering a stable and responsive platform. These specifications reduce the likelihood of pinch flats while maintaining consistent traction on challenging terrain. Backed by a lifetime warranty, the Synthesis Alloy 2.0 assures riders of Crankbrothers’ commitment to quality craftsmanship and long-term support.
