The club is holding a grass track racing event soon, so I used this as motivation to sort out the fixed wheel for my singlespeed CX bike that has been languishing in the garage for a few years, problem being an old bearing that needs to be replaced but is stuck. I recently bought a bearing removal tool for a pressfit BB and by sheer good chance, the hub is *just* wide enough to take the tool. Luckily, I was also able to find both the replacement bearings I bought all that time ago, as well as the wheel's axle and locknuts languishing in the bottom of the spare parts box.
Job done, I then had another look at the info for the event and saw that the races will be on freewheel bikes. Doh!
Oh well, at least I now have another serviceable wheel in my collection.
