I have a Corsa recumbent trike with a cowling-chainguard encircling the boom. There is a 175/94 square taper crankset, with a long spiderred bolt assembly passing through the right hole in the cowling. I’d like to go to try smaller crank arms. I have several crankset arm varieties in the 110 bcd size. Unfortunately, with 110 bcd, the chainring bolts would not clear the crank cowling hole. So 94 bcd is the max bcd pattern available for mating with the assembly that will go through the hole. I’d like to try a 110-94 spider if such a critter exists interfacing the crank to the bolt assembly. The spider would outboard the cowling so if mounted between the crank and bolt assembly, it would clear. Anyone know of a 110-94 bcd spider source?
I have some mild variety in 130 bcd if 130-94 exists, but I have much greater variety in 110 bcd.
(There are no issues of concern on the left arm on this trike; the trike has an internal gear hub drive, so triple/double is not an issue).
