But recently, it’s been dropping by about an inch whenever I ride it.
Doesn’t seem to get any worse that that, but definitely does it every time.
All those years ago, I bought another clamp as that seemed to be the advice at the time. But I never got around to fitting it as I scuffed up the seatpost and gave it a good degreasing and that seemed to cure it.
So today, while I remembered, I got that seat clamp out and filed down the lip with a metal file then used 240>500>1000 wet and dry to make sure it was smooth and there were no jagged bits. Took about an hour in total.
When I took the seatpost out I could see that the shin is in need of replacing as it’s coming apart at the back edge.
Forgot to take any pics and I didn’t want to take it apart again just to shoot it.
Hoping this will cure it until such a time as I can get the shim replaced.
Anyone have an idea of cost?
