Overall Product Rating 5 / 5

Great original Brompton part

I recommend this product

ConsNot easy, requires specialist tools

ProsGood upgrade for an older Brompton

Upgraded an older Brompton to this, which required a change in bottom bracket, a good few specialist tools, and a fair bit of effort. However, whilst a shop fitting would have cost the same as the tools, I get to keep the tools and have learned more about the bike, so definitely worth it!

To use this to replace the crankset on a 2007 Brompton, which bottom bracket would I need?

SJS Customer Service:

SJS Cycles part number : 31207 is the Brompton spec one, but you can use any 119mm JIS 68mm square taper.
