219 sprockets

I am just putting out some feelers to get some feed back about a couple of things that may be of interest to see if there will be a potential market for rear wheel sprocket carriers for #219 ( standard kart sprockets ) and also front 10t to 18t #219 sprockets 3/4in bore ( with grub screws and shaft adaptor for 12mm bore ). These are going to be manufactured in small quantities for our purpose but if there is a potential larger market then we may be able to offer these items to others at a very good price , if the demand is there. This is not a sales plug just a bit of market research that may be of benefit to others.

A couple more pics.. the center hole diameter is big enough so would be easy enough to mount on a disk mount hub or fit a freewheel on the adaptor for either crank drive or to screw onto a rear wheel.

What's the ID of that large center hole?

its 52mm, we may redesign the adaptor to allow different inserts in the center to allow different mounting configurations but only if there is enough of a demand as it will cost slightly more to produce than as the adaptor stands now.

what hubs/wheels are these made for? 19" would be something i would be interested in.. with a dirtbike hub. Any idea what mass the whole wheel will have? Just to compare this one with a bicycle rear wheel.

they are originally made for pitbike wheels/hubs

I still haven't found an adapter to mount my 219 sprocket to the disc brake mounts...

Hey G,

I would be interested in at least one drive-sprocket.
Curious about the typical (or variety) of spoke counts in these pitbike hubs?
