Integrated right hand crank and Brompton 50 tooth Chainwheel - 3/32 inch
This was discontinued by Brompton in June 2013
Currently sold out!
Warning: Last few in stock!
Availability date:
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The non-spider crank was discontinued by Brompton in June 2013 - it has now been replaced by the new better quality and more versatile "spider" crank (chanhing to this crank will also require a new bottom bracket)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)
For removal / fitting instructions, please check out this link from Park Tool

Increased gearing for Brompton
Asked the guys to increase my Brompton gearing, having specced the 12% lower option years ago when buying my bike and living at the top of a massive hill. Great service as usual, swift and transparent on process and timing, and usual lovely customer experience from the friendliest LBS in the area.
