Green 8-spd Brompton, originally uploaded by Ben Cooper.
Fitted the latest version of the 8-speed kit to a new bike today – usually, I make the parts as I need them, but this time I made all the parts first and then fitted them so I could time how long it takes.
About 50 minutes.
That’s converting a brand new singlespeed Brompton – it’ll take a bit longer if you need to take off a geared hub first…
