The cog sadly isnt anything special. So this is a point where i can save some weight as well later on.
Avoid aluminium sprockets (apart from >20t for hill climb use) as they are not Super Safe. Echo Ti would be nice, 19g of nitrided drillium for only £35, although the long boss of trials sprockets can create problems (chain line, no lock ring clearance) on track bikes, so it would probably need to be ground down a couple of mm.
