Retro Newbie
I have just bought a GT Avalanche circa 93.
The non GT seatpost size on the bike is a 27 but is very very tight. Tight enough to scratch the post as I push it in.
I have carefully re sized the seat tube to ensure it's fully round and open but to no avail.
I'm looking at buying a new seatpost in black and obviously don't want to scratch it first time on.
Anybody know what size it should be?
Am I better off getting a 26.8?
Any advice appreciated
