These are custom machined sprocket halves not just a standard sprocket cut in half! Each sprocket half is precision machined out of 7075 Aircraft grade aluminum. We custom machine each half separate to eliminate the gap found in traditionally cut sprockets.

You can order as a complete set or individually.
*We stock these gears however large quantity orders will experience a slight lead time.
*Gear Guard is only used on one side of the hub closest to the RR wheel. The gear guard is to prevent the chain from being knocked off when sliding over a ridge or something similar in the track or exiting the track. I very seldom run a gear guard due to the reduced diameter of the sprockets. Some rules require them! Gear Guard is not included and can be purchased separately.
