Product Details

Shimano Zee rear derailleur is the ideal start for a Brompton derailleur conversion.

Note: I don't give tech support to make these conversions work as there are too much variables (different cassetes and derailleurs etc) So you have to figure it out on your own. It's not so easy to get it right.
