About this part
Rear sprockets machined for the E-Ride Pro platform, on the stock bolt pattern so they go on in place of the original without adapters or drilling. Four tooth counts are offered: 40, 50, 54 and 58.
Gearing is the cheapest change on any chain-drive bike. Dropping teeth raises top speed and lightens acceleration; adding teeth does the opposite and helps on steep, technical ground where the bike is asked to pull from low speed. Pick the count against the riding you actually do rather than the number on the spec sheet, and check that the chain has enough adjustment left before making a large jump in either direction.
