Disaster has struck...
...At least in terms of getting the bike on the road in time for the NW ride on Saturday :cry:
Seat tube either isn't 27.2 or has deformed. Have trashed a cheapo post trying to open it up a bit.
Sadly, I don't have a 27.0 post to try although being Columbus SLX, the seat tube should be 27.2.
I'll try again later but I think this bike will be staying at home on Saturday.
