I need to buy a new seatclamp as the saddle is moving around. I can't buy a new seatpost as the old one is stuck.
So how do I measure the seatpost diameter without taking it out?
The seatpost diameter is smaller under the saddle where the clamp is so I wouldn't get the right measurement if I took the saddle of and measured the top of the tube.
It's an old Carlton with Reynolds 531 tubing.
According to Sheldon, it could be 27 if it's late 50's and 27.2 if its circa 1968.
I don't know when it was made.
Any ideas?
