Went and checked out this bike today. Bike is in good condition, no damage I could see other than a slightly torn seat, and the seller seems like a pretty decent guy, however he seems to have made an error in the auction - I’m pretty sure it’s a 53cm, not a 56cm.
It’s too small for me (:-() so I won’t be going for it, but if anyone’s interested, here are the measurements I took of it:
TT 52cm C-C
ST 49cm C-C, 53cm C-T
Standover 78cm
Seatpost diameter 27.2mm
