Do 12sp (XT) chains have a woeful life expectancy?
Based on an experience of one, Felix’s has ‘stretched’ prematurely. Would have had max of 1000km and hasn’t been in rough conditions. Also ran so rough even though no where near 0.75 on the chain checker, I was starting to think the roughness must be elsewhere, but ring, cassette and derailleur were all new at the same time as chain, and in mint condition.
Swapped out to a new chain, and running like clockwork. Hoping I’m not having to do this so regularly with the crap availability and ridiculous price.
