Brompton 11-Speed Conversion Kit - Black
Bromptons are great – and from the factory they’re perfect for what they’re designed for, short journeys around the city. But the Brompton design is capable of a lot more, with some modifications it can become the ultimate folding bike! Think of it like what Cooper did for the Mini – taking a very good bike, and improving it a bit...
This kit includes a complete new rear wheel with silver rim, stainless spokes, and silver hub, a new chain tensioner, a new rear frame with integral rear rack, painted to match your bike, and all the necessary fittings. The shifter is the standard Alfine trigger shifter.
Because this new rear frame is disc-ready, you can upgrade the brakes easily later – the hubs have a centrelock fitting to take a brake rotor. You can use a variety of disc brake options, including super powerful hydraulic systems.
For gear ratios, a 50t chainset and 18t rear cog will provide a gear inch range of 24″ to 99″. By comparison, the normal Brompton 3-speed has ratios from 44″ to 79″, and the BWR 6-speed has ratios from 33″ to 99″. Note: The rear cog has to be 18t, but the chainset can be 44t or 54t to move the ratios up or down.
Since this is a custom painted product, please allow 3-4 weeks for delivery.
You will need to add two links to your chain or replace the chain with one that is two links longer.
