My b-tension screw does absolutely nothing...
So I have built a bike with ultegra rear derailleur and have a 11-25 cassette. Never touched the b-tension screw from new just installed the derailleur. Anyway I thought I would have a play with it to increase the crispness of my shifting and noticed it does nothing if screwed all the way in or out. Is that normal/possible?

What a disgusting comment. Perhaps he should have to meet with the families of some victims of poor driving.

To be honest, I've noticed exactly the same thing on the last two 105 groupsets I've fitted to my bikes
