cheers for all the info, pretty sure its a specialized stout hub with a mavic x223 rim on the front. Probably easiest just to get a new front wheel to go with the fork if getting something with a 20mmm axle. Would like to keep it fairly light if at all possible although do have an older rockhopper hardtail.
Running the high mount as i was finding i was getting a fair few pedal strikes. I believe this was fairly common? Guessing the 120mm fork on the front possibly contributes to that by lowering the front end and BB.
have pinged you an email rob.
