Subcompact gearing - 42-28 possible with T47 BB?

[EnginCycle]

The Sugino rings are of incredible quality. The thing to realize is there are two versions and some are specific to certain inner rings. They need to be the ones that work with the 30 and 32 inner rings versus the ones for the 34 or 36 inner rings. The rings are flat on both sides so they can be mounted on the inner tab and the outer tab. My spider uses the inner location and the 74 ring lives on a mount that does not require spacers. The system uses single bolts on the inner and male/female bolts to mount the outer. Even though it is a single outer ring it uses the bolts for a double.

They will be available in black only at the moment and hopefully will be $150 each. If interest is big and the numbers allow there can be colors but they would be more and limited to only a few colors.

Again if anyone has questions feel free to ask here or send me a PM or email through the message system.

Thanks,
Drew
