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).
It’s also possible to have the slim Jtek thumbshifter instead of the bulkier Rapidfire shifter – especially good for the M-type bars.
Or you can have the Di2 electronic shifting, with a very neat little switch and handlebar display.
