Hello,

I have a old road bike, that has a welded seatpost clamp. However the previous owner had installed a too small seatpost, causing that the clamp is almost cracking apart. There is maybe 6-7mm space left in the seattube, if I filed the broken clamp off. I was thinking if its possible install a modern seatpost clamp there? Or if someone has gone through this, what other solutions are there?

Thanks!!
