Shimano has redesigned the 105 line of components to keep it up to date with the ever-evolving industry standards. The Shimano 105 RD-R7000 Rear Derailleur utilizes Shimano’s low-profile Shadow parallelogram design, which reduces crash vulnerability and improves shifting performance. The new construction matches the force from the hand to reduce shifting effort and also allows for more flexible cable routing options. With the RD-GS option, you’ll be able to accommodate a 11-34t cassette, perfect for a gravel/CX rig.
