Reduce the gearing (make going up hill easier) by changing from a 50T (standard on 3 or 6 speed) or changing from a 54T (standard on a 2 speed) to this 44T!

The Brompton "Spider" crankset was introduced on new Brompton bicycles at the beginning of 2013

This is a replacement 44 tooth chain ring complete with chain guard

One of our most popular upgrades - allows a Brompton with 50T c chain ring (standard gearing) and spider crankset to be changed to reduced gearing - making going up hills easier

It can be used to replace the 44,  50 or 54 teeth chain rings on the "spider" crankset introduced in 2013.

A standard 3 or 6 speed Brompton comes with a 50 tooth front chain ring - changing to 44 teeth will reduce the gearing by approx 14%
