SRAM Rival eTap AXS D1 Disc Brake Rear Right Flat Mount 20mm black

Radio shifting and the best hydraulic disc brake on the market, plus revolutionary eTap shifting logic. What more could you ask for? While SRAM could have stopped here, they've gone one step further and optimised the shape of the grip to fit hands of all sizes for comfortable, controlled braking from any position. AXS technology means personalisation is in your hands.

Reach Adjust
Brake lever fit and ergonomics is a very personal matter. Riders have individual position preferences as well as unique hand sizes and finger lengths. The Reach Adjust makes it child's play to adjust the lever for maximum control with just one finger.

eTap
Wireless shifting, battery energy management and mechatronics - the RED eTAP technology serves one goal: to offer you the most intuitive operation possible. They call the shifting logic behind it eTAP. The right lever shifts into the higher gear, the left lever into the lower gear. You can control the chainrings via both levers. Simple, smooth and intuitive.

AXS
AXS is SRAM’s new bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware.

X-Range
Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is gearing for today’s road riding. SRAM completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you’re always in the right gear.
