Overview

What makes the Shimano 105 RD-R7000-GS handle wide cassettes?

The Shimano 105 RD-R7000-GS rear derailleur carries the low-profile Shadow RD design down from Shimano's top road groups, tucking the body in close to the frame for stable, quiet shifting and fewer knocks on rough roads. The medium GS cage swallows cassettes up to 34 teeth with a total capacity of 39 teeth, which is what makes a compact 50/34 crank and an 11-34 cassette work together for climbing-friendly gearing.

It runs 11-speed Shimano road drivetrains and pairs with 105, Ultegra, and Dura-Ace shifters, so you are not locked into one build. The derailleur accepts a standard hanger and is also direct mount compatible, since the B-link can be removed for frames with a direct mount interface. At a claimed 232 grams in a silky black finish, it is a sensible, hard-wearing choice for road riders who want a wide gear range without giving up crisp shifts.

What size cassette does the RD-R7000-GS handle?

The medium GS cage works with cassettes up to a 34 tooth largest sprocket and an 11 tooth smallest, with a total capacity of 39 teeth. That covers wide-range 11-34 setups for climbing.

Will it work with my shifters?

It is built for 11-speed Shimano road drivetrains and pairs with 105, Ultegra, and Dura-Ace 11-speed shifters. It is not compatible with electronic or 12-speed road systems.

Does it support direct mount?

Yes. It mounts to a standard derailleur hanger out of the box, and the B-link can be removed to fit frames with a Shimano direct mount interface for a stiffer connection.
