With 3.5mm of chainring spacers needed for sufficient belt-chain clearance, the CDX rings are sitting outside the spider arm shoulders, so there is not a lot of support there at the moment. I haven't noticed any issues yet, just looking to improve the install.
Borrowing an idea from these trackie monsters:
Searching online I couldn't find a 130bcd chain/bash guard small enough to fit under the CDX teeth, so I'm starting with a 130bcd 39t ring which does fit as-is, but removing the teeth just to clean up the finish look as in the last photo above.
I had a FB chat with one of the trackie guys who told me about their custom machining for the spacer ring. These guys can put out > 2000 watts, which is one of the reasons why they reinforced their same-side drive in this manner. It seems like a good idea to reinforce things... my 98lb stoker being such a powerhouse and all
