Chainring was the answer I needed for a dj build that had a 10t rear driver (and no other options). Everything was machined right and bolted up to the Zee cranks nicely. Only issue was it’s not designed for wider chains … like 1/8th BMX chains .. which I assume most ppl would want? I had to spend a bunch of time with a dremel to machine out inbetween the teeth to work. I hope the design could be changed just a tiny bit to work with a wider chain … then it would be perfect!!
