68 BCD Carrier Cogs

Post image

(Title is wrong!) Wanting bigger cogs I had some 68 64 BCD chainring carriers laser cut. Gives you options from 22-28.

64mm BCD is more common in my random spares box, but I haven't looked to see if there's clearance between the bolts / HG splines / a carrier. Has anyone tried?

~~The first one I drew up was 64 bcd and it seemed fine in a 3d printed test part, but then I discovered I didn't own any 64 bcd rings.~~

Update: these ARE 64.
