Oh Dear!!!
Why new sprocket?? Do they wear at the same rate? Basically, I am changing it as preventative maintenance. I'm paranoid about it snapping, it has done 6k miles. To be honest I don't know what it looks like as the bike has spent the most part of 17 weeks in the dealers, but I hope it will be back before the spring and was thinking of any jobs that I might be able to do over the winter.
Any others you can think of?
I was hoping that it would be like changing the chain on my push bike....apparently not!
