Rob - I remember you used to ride your fixie to and from Herne Hill. I just rode to Butlers the other day and the gearing seemed very high for anything but flat ground. Was it a real hassle getting up climbs?
If anyone has a spare brake, even tatty, they're willing to sell for cheap, the forks on the bike i'm using have a hole, so i could pop a brake on for the road - no i'm not riding brakeless - tried it and it is silly scary.
