Brompton 44T BLACK crank set
The 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 crankset - with black chainwheel and cranks
This is a replacement 44 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 "spider" crankset has a few advantages over the older fixed crankset:
The chainring protector is held on with screws rather than plastic lugs so is less liable to falling off
The chainring can be changed without the need to replace the crank as well (making it easier to change gear ratio)
Better protection of folding pedal to stop it scratching the frame
Crank length 170mm

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%
