SRAM RED eTap Rear Derailleur Medium Cage

The SRAM RED eTap rear derailleur executes shifts the instant you demand. Wirelessly. It's easy to set up, clean in appearance and delightfully uncomplicated. Mechanical necessities such as a carbon pulley cage, ceramic pulley bearings, and anodized alloy artfully blend with proprietary electronic advancements to deliver a shifting wonder.

ETAP
Wireless shifting, battery energy management and mechatronics - the RED eTAP technology serves one goal: to offer you the most intuitive operation possible. SRAM designates the shifting logic behind it as eTAP. The right lever shifts into the larger gear, the left lever into the smaller gear. The chainrings you can control über both levers. Simple, smooth and intuitive.

WiFLi
SRAM's WiFLi technology serves a wider transmission range than a mechanical rear derailleur with short cage. Compared to three chainrings, it ensures faster shifting and considerable weight savings.

Orbit
Orbit technology is an innovative new form of rear derailleur motion control. It uses silicone fluid as part of an elegant and ultra-light damping system. Compared to a conventional friction clutch system, Orbit technology produces no additional resistance to the rear derailleur spring during slow or light movement. This means easier shifting and rear wheel removal. During the ride, the fluid damper holds the chain back in a refined and elegant way. With maximum reliability and chain tension, for 2-fold and 1-fold systems.
