I asked around, googled, and couldn’t get a definitive answer. Maybe one of you all know?
Is Linkglide (sp. 11sp) compatible with SRAM shift indexes? I’m guessing it’s gotta be, but 27.5 wasn’t a thing yet when I last wrenched in bike shops.
I have been blowing through SRAM xg-1175 cassettes every two months and it’s been costing me a fortune. I refuse to change chains below 0.5 stretch out of principle, and I am changing chains 2-3x per cassette as it is. I was hoping to move to LG chain/cassette (and new freehub).
This is on a gravel bike that I hate-mash everyday on a climbing route and I’m 230+ lbs.
There used to be a chart somewhere with precise information on both cable pull ratios and actual derailleur travel distance (horizontally) for Shimano, SRAM, and I think Campy as well. I don't think this is the exact version I remember, but a very similar chart is here: https://endless-sphere.com/sphere/threads/11-50t-cassette-on-cute-q100c…
If the horizontal spacing of the LinkGlide cassette cogs is the same as it is for SRAM 11-speed cogs then a SRAM shifter/derailleur might work. The caveat there is that SRAM's 11-speed MTB derailleurs are only optimized for a 42T largest cog and don't work as well if paired with anything bigger. If you tried to use the LinkGlide 11-50T cassette, I would expect that a SRAM 11-speed derailleur would have poor shifting because of the compromises in B-tension required to make it work.
tl;dr it might work if the cog spacing is the same but the derailleur's intended range is an additional obstacle to compatibility.
You could also upgrade to 1195 cassette, they are far longer lasting in my experience
