I have 2 alfines…
1st one is 2 years old in novemeber and just works (32:18), my only problems have been the ebb slacking off a coupla times and also the big bolt thing, but that's related to the kid trailer hitch I've stuck on there. I used it at the bonty 24/12 just gone and i had no problems with the 2am clag. I've raced XC with it, pottered about all over ireland with it, done things like whites level and cycled in hub deep snow.
It's been so maintenece free that I bought another for my pompino pub/commuter.
That I couldn't get to work (would not stay in gear or give me the full range) and it went back to the shop that built the wheel, they had a play and it's now gone back to the distributor for them to replace the internals. Been a week now, but they said 2 to get it accross the irish sea and back.
Only heard of 2 other alfines with trouble in 2 years, which isn't too bad.
