Miche Fixed Track Sprocket 3/32 Inch

This is used on the electric motor drive shaft of a Greenpower F24 race car! I have a bespoke carrier assembly so it is a simple matter of changing sprockets, depending on race conditions on the day. We use a choice of 14T, 15T & 16T which gives the marginal ratio differences required.

I recommend this product

I only use this on a fix wheel road bike. On fitting one wondered whether it would be up to the task and whether the lock ring would keep it secure but it works fine. I suppose its a good idea if you want to change sprockets quickly but for me I feel in retrospect it was probably unnecessary. There is certainly no difficulty removing them however,
