Crank Brothers Synthesis E-bike Alloy 27.5-Inch Front Rim

Mountain bike’s first tuned carbon wheel system for cross country/trail riding and racing.

Front and rear specific wheels tuned and optimised to address the specific performance requirements and loads of mountain bike riding.

Compliant tuned front wheel improves handling and maximizes grip and control in turns. Wider inner rim width supports wider tyre profile in front, increased volume and contact patch, and rounds tyre profile to enhance turning.

Stiff tuned rear wheel supports peak loads and enhances stability and tracking at speed. Narrower inner rim width supports narrower tyre profile in rear, improves rolling resistance, and sharpens tyre edge for grip.

Rim Height 19mm
