Product news: The brand-new Crankbrothers Synthesis Alloy 2.0 aluminum wheels are here, and according to the manufacturer, they herald a new evolution of aluminum wheels. They're so confident that the wheels come with a lifetime warranty. The new wheels are specifically tuned for the front and rear wheels and now feature improved materials, surfaces, and geometries. The result is a stronger wheel for even more confidence.
Improved materials & finish
Constructed from 6069 aluminum, the Synthesis Alloy 2.0 rims offer excellent tensile, yield, fatigue, and shear strength. These increase protection against dents, cracks, and deformation for exceptional durability. The shot-peened finish further strengthens the rim with a hardened outer layer that prevents cracks and material failure.
New rim profile
Thanks to a revised sidewall geometry and targeted material reinforcement in the rim base and flanks, the profile is more robust and impact-resistant. Every design decision is aimed at optimal performance and durability.
Tuned Wheel System
As with all Synthesis wheels, the front wheel is engineered for compliance and traction, while the rear wheel offers stiffness and stability. Specially tuned spoke count, spoke thickness, and rim geometry ensure control at the front wheel and stability at the rear – for an unsurpassed ride experience.
Lifetime warranty
Thanks to the increased robustness, Crankbrothers offers a lifetime warranty on all original Synthesis Alloy 2.0 rims. If the rim breaks, dents, or is damaged on the trail—whether due to hard impacts, cracks in the spoke hole, or punctures—you'll receive a free replacement.
Crankbrothers test facility – from the lab to the toughest trails
At its headquarters in San Clemente, California, Cranbrothers tests its components and wheels in its own facility. From massive impacts to fatigue cycles and countless trail laps, the prototypes are subjected to extreme stresses. This includes the Synthesis Alloy 2.0, which has been tested in the lab, in the field, and on World Cup courses.
We've also already tested the new Crankbrothers Synthesis Alloy 2.0. More information will be available here soon!
Crankbrothers Synthesis Alloy 2.0 – Models for three applications
The new Crankbrothers Synthesis Alloy 2.0 comes in three versions tailored to three different applications.
- Downhill: Extra robust, more material, wider rim, stronger spokes – ideal for tough descents
- Enduro: Lower weight, more compact rim bed, finer spokes – perfect for extended day tours
- E-MTB: Robust DH construction with even thicker spokes – designed for high-torque e-mountain bikes
