Will it all end in tears?
This would be via a 1x set up.
Definitely. According to the manual it’ll be well out of spec and cause you to crash and die a painful death!
In the real world probably not. I ran Shimano short cage with 11-34 no issues. Just had to adjust the b-screw.
Currently running 11-42 with shortcage ultegra and a roadlink. Sweet shifting and no issues.
My MTB’s are on sram gx without roadlink and running 11-50 with no issues. Manual rates the mech for 11-42.
You’ll need to set the b-screw for clearance on the 34 but its not a stupid range so should be able to get away without the roadlink.
FWIW the sunrace version is way cheaper than the Wolftooth and works exactly the same https://www.wolftoothcomponents.com/search?q=Roadlink
Forgot to mention all on 1x setups. Road and MTB.
Even managed to get 48T chainring with 11-40 working perfectly. Well outside spec but tis spot on. Long cage for that though.
