Brompton BLACK crankset - 50T (excl. BB)

Brompton 50T BLACK crank set

This 50 tooth Brompton "Spider" crankset was introduced on new Brompton bicycles at the beginning of 2013. In 2015 it was introduced to the after-sales market.

This is the BLACK edition 50T crankset (chainring and cranks are black).

This BLACK crankset was initially only available on the BLACK special edition Brompton range (a limitied release of BLACK edition bikes was launched as the first models of the year - i.e. in October 2016 the new 2017 range, with new model features such as integrated brakes / shifters was released - just on the BLACK edition, with standard models following later).

The BLACK components were released to the after-market during 2017 (initially they were only available on the BLACK edition bikes. Even after release to the after market, availability was somewhat limited)

This is a replacement BLACK 50 tooth crank set complete with left and right hand crank - bottom bracket is NOT included and if you are upgrading from the old fixed crankset then this should also be changed..

The 50 tooth crankset comes in a pack contains the following:
Left hand crank and bolt - black
Right hand crank with 50T chainring and chainguard (pre-fitted) and crank bolt 

Crank length 170mm
Brompton logo on cranks 

A standard 3 or 6 speed Brompton BLACK edition comes with this 50 tooth front chain ring

Also available in silver (the silver 50 tooth crank set is as provided on standard 3 or 6 speed Bromptons)
