ConsNot the cheapest

ProsQuality

Top quality component. If you are doing a gearing change to make your Brompton gradient friendly then go for this one. Top quality from SRAM apparent as soon as you remove it from from its sleeve.
Machining and anodizing top drawer and I’d say on a par or slightly above the standard fit Brompton component.
