Compatibility:

Designed for Brompton folding bikes, including the A, C, P, and T lines.

Compatible with multi-speed cassettes, supporting a maximum cog size of 28T on the A/C line and up to 34T on the P/T line.

Key features:

CNC-machined aluminum: The derailleur body, fixture, and tensioner arm are made from a lightweight, CNC-machined aluminum alloy.
