Hi,
Anybody could help me to know if they are 27.0 or 27.2?
I’m trying to install as a test a 27.2 no seat back I have and it seems quite difficult in both (don’t want to damage the seat post or apeciakly frames forcing). I doubt if they are 27.0 or maybe the seat post is wrong.
As the De Rosa has not clamp I prefer to ask before trying other methods like opening a bit; and so in.
Thanks in advance!!!
Btw theese are the bikes:
