I have a complaining freewheel hub on my Ritchey PRO Girder XC wheelset. (Standard on Raleigh RM7 MTB of 2004 I think) Tried clening a few times by removing the o-ring at the back of the body, but only last for a week after regreasing. Any suggestion of a Shimano replacement or that ANY replacement has been made by anyone? I'm desperate!!

In the process myself. So far the best value for money seems to be Merida One-twenty HFS 1000D. (the south African version) Full XT + Hayes discs + Fox suspension parts. R21k
