11-speed cassette weirdness
So, new wheels (Hunt) and I’ve fitted a 105 11-speed cassette. When I set everything up at the weekend, I gave the cassette some welly when tightening it and all seemed fine. Then it gradually worked loose for some reason. The only way it seems happy is to stick the spacer on first but I didn’t think 11-speed cassettes needed a spacer on 11-speed hubs! Have I got that wrong or should I reinstall it all but grease the threads a bit more? All set up with the spacer now and no sign of problems but I’d rather have it correct.
