The Crank Brothers Synthesis E Boost Wheelset offers front and rear-specific rims offering the right stiffness and compliance characteristics to suit their required role. The front and rear-specific inner rim widths are optimised to run wider tyres up front and narrower tyres in the rear.

Compliant Front Wheel: Compliant tuned front wheel improves handling and maximises grip and control in the turns. A wider inner rim width supports wider tyre profiles, increasing volume and contact patch, and rounds the tyre profile to enhance cornering performance.

Front Wheel features:

• Lower Spoke count
• Lighter Weight Spoke
• Wider Inner Width
• Lighter Rim

Stiff Rear Wheel:

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

Rear Wheel Features:

• Higher Spoke Count
• Heavier Spoke Weight
• Narrower Inner Rim Width
• Tougher Rim
