Crankbrothers Synthesis Alloy E-bike Rim

Synthesis E-MTB Alloy Rim

Tuned front and rear alloy wheel system for e-mtb riding and racing. These wheels are specifically designed to meet the unique performance requirements and loads of mountain biking.

The compliant-tuned front wheel improves handling and maximizes grip and control in turns. Its wider inner rim width supports a larger tire profile, increasing volume and contact patch, which enhances turning by rounding the tire profile.

The stiff-tuned rear wheel supports peak loads, enhancing stability and tracking at speed. Its narrower inner rim width accommodates a narrower tire profile, improving rolling resistance and sharpening the tyre edge for better grip.

The rims feature a welded and sleeved rim joint for additional strength. 

Rims are sold individually, not in sets.
