I went to the bike station in edinburgh on saturday - great place, didn't have time for a long rake though needed a seatpost for the khs - needed a 26.8 but they had none left - took a 26.7 off there hands for a £1 - never seen that size before, I thought they were stepped in 0.2s. Seems to fit well enough just now, I suspect I'll add a bit of coke can after a while.
