27.2 or 27.0 or 26.8? - London Fixed-gear and Single-speed

bozo · 29th August 2008

so my graham weigh seems to be putting some pretty large scores in my 27.2 post, and is a real struggle to get out again so i take it it's going to be either 27.0 or 26.8.

it's made from 853 which i thought usually gave a 27.2 seatpost, but clearly not.

I suppose my question is will a 26.8 slip?

take it to your independant local bike shop and have them ream out the seat tube.

0.2 mm doesnt seem like much, but when you can potential waste a frame by using the wrong size, it is a hell of a lot

i read somewhere it was particularly difficult to ream 853, any truth in this?

Or, take it to your LBS, ask them to measure your seat tube. And then buy a seat post that fits?

Put seatpost in lathe. Turn until it fits
