Matched 5 speed cog set 11-13-17-21-25
As you may know taking cogs from road or MTB cassettes and restaking them on Brompton can result in poor shifting. That is because the shifting ramps on those cogs were no longer aligned.
In this set, the shifting ramps on the cogs are matched, and the spacing is fine tuned. On some of thse cogs, the shifting ramps are also modified. The price of the cog set reflects such additional works.
