New Year's Greetings to all CR Members----

I have thusfar met with no success in obtaining a 24.8mm seatpost. I certainly could (and very well may) keep tyring, but I was recently presented with another option---

A local wrench/framebuilder suggested reaming out the area INSIDE the seat cluster on the frame by .2mm to accept a 25-mm seatpost, which can be easily had. (This work would be easier to perform than honing down the walls of a 25.0mm seatpost to fit the 24.8 frame opening.)

Evidently the seat tube itself below the cluster has more than enough room to receive a 25.0 mm seatpost. I just need to "get past" the seattube cluster. This is a lugless, fillet-bazed randonneur built by a constructeur in 1947.

My hesistancies are: 1. This might weaken the seatcluster structure? 2. It means the frameset will technically no longer be "original."

Advice/comments?

Thanks to all!
