Cycle Underground Rings
Fyxomatosis has taken over the full distribution of Cycle Underground chainrings, some of the better ones on the market from what I hear. Made in Australia out of 4 mm thick work hardended alumnium, the rings are individually CNC’d and are guaranteed to be perfectly round. 130 or 144 BCD rings are available for $60 each, with full custom rings (with choice of 12 chainring designs) available for $90. Black anodizing is $10 more. There are some oddball bolt patterns available, think of them for restoration projects or as a solution to those vintage cranks you got a great deal on.
