Well this is a cheeky little number. The Ti Parts Workshop 3-Speed Trigger Shifter is a custom made lightweight shifter designed specifically for Brompton which can be mounted on the left or right. It can be used as a direct replacement for the internal 3-speed Sturmey Archer shifter or more excitingly, with a little bit of magic and some extra parts, can be used on the other side converting your 2 or 6-speed Brompton to a super light external 3-speed or a hill crushing 9-speed! 

The shifter is CNC machined from high grade 7075 Aluminum with Ti-6AL-4V Titanium hardware and has a thumb trigger that can be changed from left or right orientation easily depending on usage. Not compatible with standard Brompton levers so we recommend upgrading to something special like Paul Components Canti Levers.

We have fully tested these over the past 6 months and extra parts are required to install especially for extra gear upgrades. Contact us for details and upgrade options.
