The SRAM Red AXS hydraulic disc brakes provide 80% more braking power from the hoods and 33% more from the drops, reducing hand fatigue while offering consistent stopping power in all conditions.

The Zipp 404 Firecrest carbon wheels are 58mm deep for maximum aerodynamic efficiency, paired with Goodyear Eagle F1 R tubeless-ready tyres for low rolling resistance and excellent grip in wet and dry conditions.
