It can do the job within limits. The issue ultimately comes down to how much chain slack the RD can take up. If it's not enough, you get a slack chain and all the not-so-nice things that can lead to. Generally, if you have a short cage RD, you may not have enough take-up to make an 11-36 work. It seems that most medium cage RDs can do more than the manufacturer claims.

In my case, I had a short cage RD with a 12-28 cassette and it didn't look like a Roadlink would do what I wanted, which was to run an 11-36. So I went with the Deore XT RD. In my case, the 105 was 10-speed and I discovered that the Deore 9-speed was the way to go. The only other change I needed to make was a longer B-screw. The stock one was not long enough to adjust to the needed clearance.
