The frame protector

Small wheeled folding bikes are easy to get on and off but this leaves them vulnerable to paintwork damage when you miss-judge the step over. As seen above, made to measure for the Brompton bike, this quality neoprene fabric cover with velcro fastening will keep your paintwork intact.

Please see the Brompton upgrades page for ordering the Scuff Muffle.

Sorry out of stock due to manufacturer letting me down - re-sourcing and hope to be back early 2012.

Lower gearing for all Bromptons (1,2,3,6 and 8 speed)

This is probably the most asked question I get about the Brompton bike, if you have got the smallest Brompton chainring (44t) and the largest rear sprocket for your model and you still want lower gears then I can supply (and fit if required) two new options.

Stronglight 40t chainset, a smaller chainset by the manufacturers of the Brompton chainrings, the right crank arm is the same style as the current Brompton so you can either retain your left crank with the Brompton modification to stop the folding pedal touching the frame or fit the new one supplied with a modification to do the same. It will use your current bottom bracket cartridge. Supplied with a bespoke laser cut aluminium chainguard £49.99, please see Brompton Upgrades page for ordering.
