An Impeccable Blend of Form and Function

The SRAM Red eTap 11 speed rear derailleur executes shifts the instant you demand, wirelessly.

It is 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.

At the core of this derailleur is the SRAM eTap technology. eTap, the first wireless shifting system, has advanced power management and mechatronic technology. SRAM's stated purpose for this line is to facilitate the most intuitive and consistent shifting available.

The updated version of the Red eTap RD utilizes WiFLi (Wider - Faster - Lighter) tech to deliver a wider range of gears up to an 11-32 cassette.

X-SYNCH pulleys borrow innovations from SRAM 1x chainrings with the implementation of a narrow-wide tooth pattern for optimum chain engagement and power transfer.

Cutting edge wireless shifting tech? Check. Maximum efficiency and chain management? Check. Clean aesthetics? Check. SRAM has knocked this one out of the park so you can knock off the miles with confidence.

Subtle but nice upgrade, batteries not included

Upgraded my red wifli Etap Rd with this updated version, primarily for the fluid damper as I use it for gravel. I've only used it for a handful of miles, and this initial impression is relative to the RD it replaced. A few observations. Unlike the photos and the previous gen rd, this item does not come with a battery, a big negative for the price. It's also heavier than the old one by about 25%. The led light is brighter which makes it easier to see. It paired up with my shifters with no issues. The cage is slightly smaller to compensate for the larger pulleys providing about the same chain wrap. I use it with a 36t large cog and seems to be able to shift the wide range slightly better than the original rd, though not as well as either with a 32t. The upper pulley is concentric with the cage pivot rather than being offset which means the pulley gap to the sprockets is now independent of the cage angle which is a plus for a wide range 2x system. The shifting actuation appears slightly faster and so far feels slightly more precise, but more similar than not. The fluid damper works to significantly reduce chain slap and seems to be effective. The lower pulley uses narrow wide teeth which should help keep the chain inline. Time will tell if the cost is worth the upgrade, it's expensive but the features seem beneficial. Will review again after some time.

Gives you broader gear choices with the great SRAM E Tap derailer and system

I needed some more gears as I mature as a cyclist and person. SRAM E Tap is fantastic. I have had it for more than 5 years and it has yet to miss a beat. Set up is almost idiot proof and very much one and done.
