I bought one of Cotic’s standard builds. Long mdium with flat bars. Run 44:17 for my commute – 12.5 miles each way. changes have been:
A set of London fixie spacers so that I can run a 17t groove armada sprocket.
Recently swapped the front v brake for an Avid BB7
Swapped saddle to a Specialized BG one.
Added mudguards which is more hassle than it should be.
Overall very happy with the bike. Good fun commuter.
£600 for base bike. Probably ~ another £100 or so for additions/changes
