An improvement on the original design.
the cluster gear is fitted with a high-duty Torrington needle roller bearing on either end. This does away with the common failure mode in the race of the original style. The cluster is designed with the wider top gear face as on the 1932 up gear. This makes it interchangeable from 1915 thru 1936. The standard thrust washers are used at the ends of this cluster gear the same as on an original gear. All gears and shafts are made with the proper alloy steels and are properly heat-treated to the appropriate depths. Gear teeth are professionally cut and properly tooth rounded for easy shifting.
