The best never rest.

The SRAM Red 22 rear derailleur is the gold standard in 2x11 rear derailleurs. SRAM doesn’t rest on its laurels, though, and this Red rear derailleur is even better than previous iterations.

The Red 22 rear derailleur still relies on SRAM’s groundbreaking 1:1 Exact Actuation. That means that with each shift, the derailleur pulls the exact same amount of cable, regardless of what gear you’re in. So, when one shift is set up perfectly, they’re all set up perfectly. The new Red 22 rear derailleur also uses a new low-profile, titanium mounting bolt to reduce weight and wind resistance.

SRAM is still using its incredible Black Box ceramic cartridge bearings in the pulleys, but the inner carbon fiber pulley plate has been stiffened for more precise gear changes. The pulleys themselves were also redesigned for lighter weight and improved durability. The jockey wheel's profile has been optimized so that the chain will glide more efficiently over the tooth profile as it threads through the cage. This, along with SRAM’s new elastomer coating, reduces noise and smooths operation at the pulley wheels.

Crisp, light, and smooth

As always Sram RD's are always delivering a quick and accurate shift. This is one step better in my opinion over the force or red 10 speed iteration. Really fast and smoother shifts than the 10 speed generation. Setup is easy and it was not picky on cable tension.

Love it

I bought this in the med. range for the hills and mountains out here in Italy. Such a beautiful piece! Carbon everywhere. Great investment and even better performance on the bike. Consider the larger option if you wish to attack serious climbs or some Gran Fondos.

Under tech specs it says capacity 31T, but under description it says 28T? If I want to run a 11-30T cassette will this derailleur work? or do it need the medium cage?

Best Answer Responded on

Clearing "a 28T cog" is not the same as capacity. . . You'll likely need a medium cage to run an 11-30T cassette, as the capacity with a 50/34 or 53/39 (the two most typical chain ring combos) is 35 and 33 respectively ((30-11 = 19) PLUS EITHER (50-34 = 16) OR (53-39 = 14).

Does the medium cage have capacity for a 32t cassette?

Yes... the medium cage will handle up to 32T
