No sure Rob. I'll have a look the morra.
Are you wanting to try it for size because yer no sure what size you need kinda thing?
I've got digital vernier calipers but the problem when ye measure a seat-tube you can only measure the very top and on an old frame you can never tell if top of tube has been squeezed in a bit giving a false diameter.
Ay, I've tried a 31.6mm and it'll no go and 30.9mm is fair rattlin :facepalm:
Am gawnny buy a NEW post for this build and a dont want to f#ck it up.
I've had the vernier oot already and I'm no gettin a good measure due to the curve 'o' the hole :shock:
BUT! I've been rollin aboot the flair all morning.
I re-tried the newer 31.6mm still no joy, then tried a used/worn 31.6mm it went in 'kin snug "phew".
Torch oot looked down the seat tube, I could see patches of corrosion (that thing when you mix two metals) not rust. Oot with the wet'n'dry + a wee touch of oil, then some green nylon pad to polish it up. Then got the newer seat post + a wee film of grease, FM I've never seen tolerance like it on a seat post its like a piston in a cylinder. That fecker ain't gonna shift when its been ridden :facepalm:
