Brompton NuVinci Kit


The NuVinci CVT (Continuously Variable Transmission) can be fitted to a Brompton, using my custom rear triangles, with an optional disc brake. I also make the rear triangles with an optional integral rack.

The NuVinci has a range of 380%, that’s between the 8-speed and 11-speed Alfine hubs, but it also had a stepless gear change – there’s no clicks, just a smooth transition from the bottom of the range to the top, using a twist shifter.

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 6-bolt 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).
