HRD Shift-Brake System:
True one-finger braking is at hand. SRAM have overhauled their hood and lever architecture and achieved breakthroughs for fit across all hand sizes and easy access to powerful and smooth, easy braking from anywhere on the bar. Independent reach and contact point adjustment allow for highly personalized setup, with no risk of pinching your fingers or bottoming out on the bar no matter your settings. Better finger wrap on the hood means less fatigue on long days, and Bonus Buttons let you shift or control ANT+ devices with your thumbs. The caliper is not only stiffer, but lighter too, with phenomenal pad clearance for rub-free operation. All that and they still managed to remove 83 g from the pair.
Features:
- One finger braking from the hoods or the drops
- 83 g lighter than the previous generation
- AXS enabled for easy setup, personalization, and reliability
- eTap shift logic for intuitive shifting
- Bonus Button provides ANT+ device control or auxiliary shift option
- Optimized hood shape fits the widest range of hand sizes
- Carbon brake lever for light weight
