Sram GX Eagle 12-speed B2 rear derailleur for mountain bikes, moon grey
(23 reviews)
10/52 cassette capacity, compatible with Eagle 12-speed range (nx, gx, x01, xx1)
Our opinion
David G.
Former professional team mechanic
Eagle is synonymous with escape. The new range brings even more simplicity. It is compatible with itself and allows the use of a cassette up to 10/52. Of course, the 10/50 remains perfectly compatible. This derailleur features Roller Bearing Clutch technology. The stability of the derailleur is increased to maintain smoothness and precision when changing gears, even on very rough terrain. This also prevents the chain from hitting the base of the frame. The cage has also been redesigned to improve transmission and indexing precision. The chain is always under tension.

Published Nov 01, 2022 at 09:08 pmGood material. Bought with GX shifter. Used with existing 11-50 cassette. Easy installation with a few tutorials. Gear shifts much smoother than with the SX. Very happy with my purchase. (Translated review)

Published Oct 25, 2021 at 06:12 pmThe order and shipping are very easy. Very attractive price and in-store pickup without issues and with a lot of kindness. The derailleur feels sturdy as soon as you open the box. There's nothing to compare with the NX model. Just remember to take a new derailleur cable as it requires a longer cable length. To be seen over time but I doubt I will be disappointed! (Translated review)

Published Oct 25, 2021 at 05:45 pmHello everyone Very fast shipping, super packaging In replacement of my nx derailleur, the gx derailleur is more precise, installation and adjustment without difficulty. I recommend the product and the site. Have a good day (Translated review)

Published May 20, 2021 at 10:38 amFirst impression on a SPECIALIZED Epic upgraded from 11v to 12v... it's a good compromise the GX range is efficient, the gear shifts are precise and fast. After 4 months of use no problems, an initial adjustment and that's it. I recommend Mat riel V lo fast shipping and top prices. (Translated review)

Published Mar 25, 2021 at 04:35 pmMounted on my Gravel to fit a larger cassette, it is very precise and reliable. The cage shock absorber is much more reliable than Shimano's which easily seizes up. (Translated review)

Published Mar 25, 2021 at 02:28 pmIn replacement of an NX, no comparison... much sturdier. Cheaper than an XO and barely less heavy... (Translated review)

Published Mar 22, 2021 at 09:01 pmSuperb derailleur, precise gear shifting replacing a SRAM SX. Top site and fast shipping. (Translated review)

Published Mar 21, 2021 at 10:11 pmBought as a complement to a GX Eagle shifter + Sram 12v chain. Replacing a Sram GX 11v group. Quality functioning derailleur. (Translated review)

Published Mar 19, 2021 at 07:31 pmQuick shipping to the relay point, SRAM material meets my expectations. Easy assembly, but the adjustment documentation with the provided tool refers to the SRAM services website. A tailored memo would be nicer. (Translated review)
