My bike got a bit mucky on Saturday's forum ride to Glasson Dock so I gave it a good clean today, especially the wheel rims which were pretty greasy, leading to some very squealy braking. I scrubbed them with citrus degreaser.
While doing all that I noticed something that would explain the occasional clunky gear shift that I suffered on the ride - the freehub could move in and out by several mm meaning that the cassette could move with it while I was changing gear; a moving target for the chain!
I was a little stumped until I remembered a major problem with the freehub on a ride last year - a sealed bearing had disintegrated. I then looked at several of my old freehubs to see if any of them might be a suitable replacement, but I think that I ended up putting a new bearing in instead. It turns out that I must have got my spacers mixed up! There is one that goes between the nut on the drive side and the outer bearing on the freehub. When I looked today I discovered that the spacer was a few mm too short. I had a hunt around and found what was probably the correct spacer. It all tightened up nicely once I used that instead of the short one. I was surprised that I hadn't noticed the problem when I first fixed the freehub. Still, it seems good now.
Oh, and I decided that using grease on the freehub pawls had not been a good idea. The freehub moving in and out had sometimes left a gap through which detritus could get in so the inner mechanism was a mess. I am amazed that the pawls had still managed to engage when pedalling. I cleaned everything and used a light oil as a lube instead.
I like to have the nose of my saddle pointing slightly down to prevent '
undercarriage erosion' on longer rides. Unfortunately, my saddle had been a bit too level for me on Saturday so I am now suffering the
'rubbed raw perineum from hell'! I have now altered its angle...
I will go for a short test ride on the bike tomorrow. Standing up!
