Thoughts on SRAM Gx??

[icebiker]

My 10 speed X9 rear derailleur is toast after 5 years of trusty service. SRAM no longer makes X9 and the only alternative I can find is GX. However I have read multiple posts that the B-tension screw on these is weak and prone to breakage or bending. Anyone with experience with these? If bad, any other alternatives? Harder to find 10 speed these days. Don’t want to have to change shifters either. Thanks.

not sure on the 10 speed stuff, but my gx eagle has had 0 issues with the b screw adjustment, they are a bit touchy on the adjustment, but thats probably because there are so many gears on there.

I also had issues with the 10 speed gx b screw. My cassette was 11-42, over the ratings of the gx. Bent the b screw right from the start. Then used one of those links that lowers the derailer about 1/2", then it was fine. Forgotten the name of the link but its common....my link was from JGbike, wolf tooth also has.

I have a 10 speed x9 (non clutch) derailleur lying around if you want it. I’ll probably never use it for anything.

GX is basically an X9 derailleur. It's super easy to replace the b-tension when it bends. They bend because folks try to run them with wide range cassettes which 10 speed was never designed for. Anything over a 40t is asking for problems. Best option is to stay 11-36 as 10 speed was made for and run a smaller ring if needed.

Thanks Jim. I’m running 36T so no worries there.

I have an x9 you are welcome to as well. Otherwise it is being dropped off with the parts bin this winter to Second Life Bikes

Thoughts on using the Wolftooth Goatlink/Roadlink? Seems like this would help some of those issues.

Not for me though. I'm still thinking 1x10 11-36 was the pinnacle of MTB gearing.

Thanks all for your input and offers to help. Thanks Lefty and Utah for the spots!
