Hi all, Am looking for a fixed size reamer to clean out seat tubes. Generally all work is on Colnago frames so needs to be 27.2mm. (I make 1.07087") I don't know if that is the exact size of the reamer or if it is a smidge larger. I had enough of standing over a frame and putting most of my 200lb mass onto a seatpost only to end up with a ghastly zig-zig down the pole even with suitable lube. Help, advice and tools for sale greatly appreciated as always. Anthony Kinder Perth, Western Australia
