My rear Evo SP hub shit itself a week ago on a descent after a bearing came apart and tore the internals to shreds. The wheel set was bought about 18 months ago, the bearings were on their way out and the freehub body chewed to buggery from my cassette.
Sent the whole wheel back to Hope who replaced the whole hub, re-laced the wheel and sent it back Fed Ex, all FOC. It's really useful being able to deal with them directly instead of going through a shop.
We don't expect anything less these days but I thought it worthy of a mention
