Shimano Alfine hub gears can be fitted to a Brompton, using my custom rear triangles – you can have an 8-speed or 11-speed with an optional disc brake. I also make the rear triangles with an optional integral rack.
The kit includes a complete new rear wheel, new rear frame* in a colour of your choice, new chain tensioner, gear shifter, and fittings. Depending on your Brompton, you might need a new chainset and/or chain, I can supply these if needed.
Because my new rear frame is disc-ready, you can upgrade the brakes easily later – the hubs have a centrelock fitting to take a brake rotor. I offer two disc options, the mechanical BB7 (reasonably powerful, simple to service) and the hydraulic Hope Race X2 (very light, very low maintenance, very powerful).
Want to add a rear disc brake? You can find them on the Disc Brake Page.
The kits come with a Rapidfire shifter as standard. For Bromptons with M or H bars (the ones that aren’t straight), I strongly recommend the Jtek shifter:
Or you can have the Di2 electronic shifting, with a very neat little switch and handlebar display.
