starting out with ss won't really prepare you for fixed as such. i was ss on my first fixed bike for a little while, but everything changes when you go fixed. i would just jump straight to fixed, but don't forget about the front brake, like rhb already pointed out.
They had that one in medium, and another polo one in small, but nothing in XL or L. They did have some other chunk hoodies, I got myself a couple at £20 each. Bargin.
big man, what colour was the "other polo one in small"? if you're around there again soon, would you sort a ginger out?
restoration. pretty good one at that
