I've got a 2017 Specialized Tarmac and think my mech hanger is bent (Gears index fine but chatter on one or two of the middle sprockets)
I bought a new hanger and it's shorter than my current one.

Further investigation suggests that Specialized make a "short" and "long" mech hanger.
The long is listed as up to 32T, so will I be alright using the shorter one with my a Short cage Ultegra 6800 mech with a 28T cassette. I can't find anywhere that says what the max size for the "short" one is.

    Probably should be fine. I've got a Alpe D'huez Road Fairy on my Rourke which essentially lengthens the mech hanger, it was capable of up to 29T and with this link, now caters for 32T.

    What's the difference in length?

    Off the top of my head I can't remember, it's not much though (5mm maybe)

    Difference in radius between a 28T and 32T cassette is 8mm.
