I want to use the Ultegra cassette with a 32T max cog with a DA9100 RD and 34/50 compact. Yes, I know the RD is rated a 30T max. I'm generally pretty careful about not cross-chaining into big/big and small/small. Still, I'd like to make sure that if I accidentally go big/big that the RD doesn't rip out. In order to do that I had to size the chain so that it's slightly too long. It sags in the small/small, but I can go big/big without the RD looking like it's going to explode (too much). Also, the upper pulley clears the 32T. The only problem I can see is that maybe I get some chain slap or there's a higher likelihood of the chain bouncing off if I accidentally go small/small. Is there anything else?
