Fitting to a Brompton?
If you want to fit to a Brompton and you don't have the official bracket you will need:
A replacement dynamo lamp bracket only
(code: Q101219 reference: QVBKTFLAMDYN-LED) used in combination with ...
a CatEye center fork light bracket (#5342440) this is just for the CateEye adaptor and will not fit without the correct Brompton bracket (we have tried)!
