I have that with my wrists! Doesn't bother me at all though... Sometimes my fingers will just 'lock up' They really hurt and I can't straighten them without using my other hand to straighten them... Anyone else get that? It rarely happens, doesn't really hurt, just bloody annoying! I don't really get achey etc after riding though, although I usually just play about doing small tech stuff, so I'm not throwing myself at big walls etc...
