Crankbrothers Synthesis Enduro Alloy 2.0 Rim - Tuned Front and Rear Specific
Crankbrothers Synthesis Enduro Alloy 2.0 Rim - 6069 Aluminium, Lifetime Warranty, 30mm Front / 28.5mm Rear
The Crankbrothers Synthesis Enduro Alloy 2.0 Rim represents the next generation of their unique, performance-oriented alloy wheels. This 2.0 version maintains the revolutionary Tuned Wheel System concept—where the front and rear wheels are specifically engineered for their distinct tasks on the trail—while dramatically boosting durability and reliability.
Key Upgrades for the 2.0 Version:
Improved Material: The alloy has been upgraded from 6013 to 6069 Aluminium Alloy, delivering significantly superior tensile, yield, and shear strength. This drastically enhances resistance to dents, cracks, and deformation.
Enhanced Finish: The rim receives a shot-peened finish, strengthening the outer layer and increasing fatigue life and crack resistance.
Reinforced Geometry: The rim profile has been re-engineered with thicker rim walls in high-impact areas to boost durability and reduce the risk of pinch flats.Lifetime Warranty: Due to the enhanced strength, the 2.0 rim is now covered by a Lifetime Warranty for the original owner against defects and on-trail damage that prevents the tyre from holding air.
Tuned Performance Concept:
The Front Rim (30mm internal width): Engineered to be Compliant. The wider 30mm inner width enhances tyre volume, increases the contact patch, and promotes better grip and steering control. Designed for a 28-Hole count for subtle vertical flex.
The Rear Rim (28.5mm Internal Width): Engineered to be Stiff. The narrower 28.5mm inner width and a 32-Hole spoke count maximise stability, power transfer, and durability, ensuring precise tracking when smashing through rough terrain.
Choose the Synthesis Enduro Alloy 2.0 Rim to build a world-class, custom wheelset that is perfectly tuned for aggressive Enduro and All-Mountain riding.
Tuned Front/Rear Concept: Different widths, profiles, and recommended spoke counts/tensions optimise performance for each end of the bike.
High-Grade Alloy: Constructed from premium Aluminium, offering enhanced resistance to dents, cracks, and deformation.
Front Grip: 30mm inner width on the front rim enhances tyre volume, contact patch, and cornering grip.
Rear Stability: 28.5mm inner width on the rear rim enhances stability and tracking under load.Enduro Ready: 20mm rim height and reinforced geometry built to withstand the rigours of aggressive trail and Enduro riding.Warranty:
