crankbrothers Synthesis Alloy 2.0 Enduro 1/1 Rear Wheel - Shimano MicroSpline29 Inch

The crankbrothers Synthesis Alloy 2.0 Enduro 1/1 rear wheel is a rear-specific enduro wheel built for strength, durability, and consistent performance under load, using upgraded 6069 alloy and a shot-peened finish to extend fatigue life. It pairs a re-engineered rim profile with an Industry Nine 1/1 hub to deliver reliable engagement, improved impact resistance, and long-term durability, backed by a lifetime rim warranty for added confidence.Key Features and Benefits:6069 alloy rim construction: The move from 6013 to 6069 alloy increases tensile, yield, fatigue, and shear strength, which improves structural integrity under repeated impacts and heavy loads. This results in a wheel that maintains shape and performance over time with reduced risk of fatigue failureShot-peened rim finish: The shot-peening process strengthens the surface layer of the rim by introducing compressive stress, which improves resistance to cracking and wear. This leads to a longer service life and greater reliability in demanding conditionsRear-specific rim tuning: The rear wheel uses a stiffer and stronger build with a 28.5mm internal width and reinforced profile, designed to handle drivetrain forces and impacts. This improves power transfer and reduces the likelihood of pinch flats during aggressive ridingRe-engineered rim profile: Updated sidewall geometry and material placement in the rim bed increase impact resistance and durability. This helps the rim absorb hits more effectively while maintaining tyre support and stabilityIndustry Nine 1/1 hub with 4° engagement: The 1/1 hub delivers fast and consistent engagement, allowing quicker power transfer when pedalling resumes. This provides better control on technical terrain and improved responsiveness out of cornersLifetime rim warranty: Coverage includes cracks, dents, and impact damage that prevent the tyre from holding air under normal riding conditions. This reduces long-term replacement costs and supports continued use without concern over premature failureThis rear wheel is built to handle repeated impacts and sustained load without loss of performance. The stronger alloy, reinforced rim profile, and rear-specific stiffness work together to reduce deformation and maintain consistent tracking. Combined with the fast-engaging hub and improved fatigue resistance, it supports efficient power delivery and dependable performance across long descents and rough terrain.Choose a rear wheel that is designed to last through hard use and repeated impacts. The Synthesis Alloy 2.0 delivers consistent strength, reliable engagement, and long-term support with its lifetime warranty.Specifications:Hub - Industry Nine 148x12mm 1/1 hub.Rim - crankbrothers Synthesis Alloy 2.0Hub engagement - 4°Spokes - Pillar SR TB 2018Spoke count - 32Inner Rim Width - 28.5mmLifetime rim warrantySYNTHESIS ALLOY 2.0 LIFETIME WARRANTYCrankbrothers offers a Lifetime Warranty to the Original Owner/Purchaser of Synthesis Alloy 2.0 Wheels or Rims, covering defects in materials and workmanship of the rim specifically according to the conditions listed below.
