This may or may not make any sense….
My beik has a Direct Mount hanger and I currently run a Shimano XT Shadow Plus rear derailleur without the upper link which is the correct way to set up such a derailleur with this hanger.
But….I want to run a Sunrace 10sp cassette with a 42t large sprocket. It seems pretty well documented that Shimano derailleurs don’t like 42t sprockets, even with One-Up Rad cages, Goat Links etc. But (again…..) it has occurred to me that if I put the upper link back on my derailleur and use it with the Direct Mount hanger, that will push the derailleur back maybe 2cm, and as such may by coincidence be ideal for the 42t sprocket? I don’t currently have the cassette to try though.
Anyone done this?! Plan B would be to buy an 11sp derailleur which is designed for a 42t sprocket, but I’m tight.
