Ultegra rear mech help
Hi guys,
Looking for gearing help, I'm putting together a new bike and upgrading the groupset, however I've started pulling out my hair a bit... please can anyone help?
I'm upgrading to a Ultegra groupset (6700), running a 11-28 rear cassette on a compact 50:34t
Question: Should I run a short cage or a medium cage on the rear mech ?
thanks in advance

I used to go that way to work. It's nasty and congested. I doubt any changes will make the congestion worse.

Why would you need a 32 if you're running a compact? Not quite sure why you'd need a 28 with a compact, but there we go
that bait is really smelly
Or get a medium cage if you may be thinking of using a 32t eg on alpine climbs. Negligible weight difference.....
I have Dura Ace but have an Ultegra long cage for a 32 Ultegra block I will use for the E'tape.
Thanks guys, that is brill!
shimano's own tech blurb says 28t max so you're good to go with
the better looking SS

You have a 33 tooth difference (28-11+50-34). Ultegra 6700 short cage mech has a capacity of 34 teeth (cf. Wiggle's spec page).
Short cage looks nicer and has enough capacity, so go with that.
