Well I've had a whole day of fettling today, and I'm feeling remarkably pleased with myself.
My bike is showing its miles and I've been collecting bits. I probably should have waited until spring, but I decided to go for it.
So I took off the chain, front mech, crankset and removed the rings and cleaned the spider. One of the bearings was pretty much seized, and the axle had obviously been rotating inside it, so I had a quick trip to Edinburgh bike for new BB shells.
I removed the bar tape, changed all the cables, then rebuilt the whole lot. The front mech has been dodgy for a while, I bent the cage at one point and managed to straighten it, but it has never been quite right since. The whole bike is Tiagra, but I managed to get a 105 front mech in Edinburgh Bike sale for less than a Tiagra one. On the stand it is changing very well, although the trim function on my shifter seems to be borked. It gives a crack but doesn't move, which was one of the reasons for changing the mech. However small to big shift seems much better.
So I have new:-
BB cups
105 front mech
chain
cables
bar tape
I have a new rear mech in a box, and considered changing it as well, but I didn't see the point in doing it just for the sake of it.
That might not seem a lot to some of you guys, but considering a year ago I didn't even appreciate that bikes needed maintenance, I think I'm getting there!
