More info

On older (pre 2013) model Bromptons, the Right hand crank (as you sit on the bike) and chainring were integrated - that's this one.

The non-spider crank was discontinued by Brompton in June 2013 - it has now been replaced by the new better quality and more versatile "spider" crank (chanhing to this crank will also require a new bottom bracket)

This 50 tooth chain wheel fits all Brompton bicycle models.

It attaches to an ISO standard square type spindle as used on the FAG bottom brackets supplied by Brompton. (Please note this is not compatible with the JIS bottom bracket spindle - such as those used on 2013 onwards Bromptons)

Tools required:
CCP-22/CWP-7 - Crank puller or equivalent tool
Small flat head screwdriver (to remove cap on crank)
14mm socket (or CCW-5) to undo the bolt holding the crank in place 
Grease (such as PPL-1 from Park Tool)
