Rohloff Disc Brompton

Rohloff Disc Brompton 4, originally uploaded by Ben Cooper.

Not the easiest Brompton conversion I’ve done 😉

Rohloff Speedhub in the back, SON Delux hub dynamo in the front, Hope X2 hydraulic disc brakes all round, and an Edelux front light.

It needed a new rear triangle, new forks, and quite a bit of custom machining…

    1. I didn’t weigh it, sorry – but probably 13kg or so I guess. A normal 3-speed is about 12kg, add about 750g for the Rohloff and a bit more for the brakes.

      If you click on the first picture it’ll take you to my Flickr stream where there are a bunch more pictures.

    1. Only the XS model fits the standard Brompton forks, but since this bike is getting disc brakes anyway, I had to make new wider forks which could take a 100mm disc hub – so the Delux fits fine.

      Years ago, before the XS was made, I used to spread the standard forks out to 100mm to take a SON – that worked too 😉

      1. The brake lines just follow the normal routing until the rear pivot, then they cross over to the left side – they don’t mind folding at all.
