I-Spec-EV
I-SPEC EV creates a clean and action-optimized cockpit that provides greater focus and flexibility for a wider range of riders.
Benefits & Features
- Wider adjustment range allows riders of various styles, preferences and body styles to adjust to the optimal position.
- Ergonomic design, quicker lever access, and light operation enhance rider comfort and concentration.
With its wider adjustment range, I-SPEC EV levers can be adjusted to the optimal position to match a wider range of riding styles (ENDURO/XC/etc.), rider preferences and rider anatomies (hand and arm alignment). I-SPEC EV increases brake lever rigidity by moving the brake clamp position inward to create an extra point of contact between the bar and the lever. This additional bracing drastically increases bike control and braking engagement while maintaining space between the clamp and support point for other handlebar accessories.
