I recommend this product
ProsWhen the going gets steep this helps.
I needed to reduce the gear ratios on my Brompton to cope with extended touring in Scotland where the landscape can be diagonal. The service and delivery was exemplary as always.

Crankring for Brompton
09 Mar 2020
Could you recommend a crank ring 50/52t I could use fitting to a 5 arm 110 bcd hollotech cranks, that I would like to use on a Brompton.


SJS Cycles part number : 11053 would work, but generally Hollowtech 2 cranks do not fit perfectly.
