105 chainring on Ultegra(3 posts)

Would the 105 B type 50t chainring work well on a Ultegra b type crankset(53 39).My days of spinning out a 53 12 are over and the 50t would give me a more practial range on the big ring.The official word from shimano is not compatable but I don't see why not maybe a very slight loss in shifting performance but it should be better than a ring without ramps and pins.I know there are other solutions available but all are more expensive salsa pro 60$,TA sets only
105 25$

It will work fine, maybe even better since that is 3 less teeth to jump.

You probably should lower the derailleur so that it clears the big ring by 1 to 2 mm. Also re-adjust the shift cable.
