It's odd to me, too, that Shimano doesn't have a medium cage DA.
I like the flexibility of the current Shimano cranks where you can switch chainrings on the same crankset -- 53/39, 52/36, 50/34, etc. And if I needed to go real low, I'd swap out the DA rear mech for an Ultegra one. The good news is that the Ultegra Di2 rear mech is way less expensive than the DA one, so it's really not a big deal to have one in the spare parts bin that you can swap in when needed.
Yea, it's frustrating because there are very few races where I need a 34 - 32--namely, the Mt. Washington Road Race--and It would be really nice to just use the same set up all the time. But it's not the end of the world

I'm running a mechanical RED derailleur on my Ritchey and it takes an 11-32 cassette without problems, I run it all the time.

The elephant in the room: why the heck don't all these companies sell multiple cage options that are designed to be changed by the user?

I'm building up a Colnago C60 and want to be able to run an 11 X 32 for uphill climbs like Mt. Washington. I was going to get Dura Ace di2 and then use the Wolf Tooth Components Road Link to run a 32 on the back. I contacted them and they said that though they haven't tried using it with eTap, they see no reason why a 32 wouldn't work.
Before I place the order for etap, I wanted to see if anyone here had any thoughts as to why, or why not, it wouldn't work.
Thanks!
Hi there...
I've been thinking about this setup also. I run Red22 mechanical. I ended putting in a Force 11-32 cassette and changed the RD to Rival Long Cage. Works fine. But I just ordered the RoadLink and gonna see if i can put my short cage red22 RD back on.

I was looking into making a compromise with a regular Red RD with the Roadlink too and here's what I found out:
1. Yes, it probably will give you the clearance for the 32t cog. But not sure how the B screw will turn out.
2. Chain wrap capacity could be an issue as someone has mentioned in this thread. I think the regular Red RD has a capacity of 33t so while you could clear the 32t cog, the RD won't be happy with the 37t capacity.
And Mr.Gib, unfortunately the geometry of short and long RDs are different at parts other than the cages

Based on your experiences, do you think combination of 11-30 and the eTap short cage RD would work with the Roadlink even if 11-32 didn't?

You can use one of these cages (or others) to make a DA (mech or DI2) RD work perfectly with 11-32, with the added drag relieving benefits of ceramic bearings and an oversized pulley wheel. Cheaper than buying a spare UDI2 mech as well.

Cool. Not seen them before. May get one and see if it works.

I've done it without Roadlink using a cable operated Red derailleur. 50/34 and 11-30. Works great. However it does depend on your frame's hanger. An extra short hanger will restrict the max cog size. I did it on a Cervelo R3SL.
I expect the Etap derailleur has the same geometry as the cable operated one.

A 9070 rear will actually work with a 30 as well.
Sometimes the frame makes a difference to.. 30t on my parlee is ok.. 32t no. My wife madone 6 can run a 32t. Both have 9070 rd.

Interesting, a couple posts back another user tried it, and said it didn't work. Mind sharing some pictures?
