if they stand up to beach riding and the odd dip in sea water then they will last anywhere!,

11 speed going on my xc hardtail when they arrive… will never have derailiers again on a hardtail…useless in long grass in summer,clogged and jumping in winter…
but i dont race and im not wieght concious with builds, 😆

Tf – are you l;ooking to get rid of your alfine then?

Loving mine. I thought I was building it into winter bike but I can't stop riding it! Having said that I'm going to swap mine out into a bike for my wife and buy the new version for me – not cheap though £375 + shifter and fitting kit.

The shifting takes a bit of getting used to. Having to ease back slightly to make the shift is a pain sometimes on big push hills but being able to shift down on the freewheel going into corners or prepping the right gear prior to getting going is a big bonus. So quiet as well. I used mine at set2rise and it was great in the mud. could be fantastic on a muddy mayhem.
