Hi
The B tension screw on my Ultegra 6870 Di2 rear mech doesnt appear to be anywhere near its stop?? The derailleur seeems to hang there without that much tension? Is this normal for Di2?
My mechanical Ultegra bike has lots of tension in the rear mech and the jockey wheel is very close to the largest cog in casette??

I did recently fall, and bend the rear hanger? is there a tension spring in the rear mech fixing location that may have gone or is the Di2 rear mech just meant to be loose????
Sorry for not so accurate description but I have tried set up. re indexing and ive even got the softare and updated everything and it all checks out but my gear changes just arent that crisp and 1 or 2 gears are a little 'clicky'!!
any help or advice would be very welcome?
Thanks
Jon
