Also note that this front derailer is intended for a large chainring of 42 teeth or smaller and 14T of total difference. I doubt there are a lot of people running an XD2 road triple with a 42 tooth big ring and only 14T of difference. What would that be: 28/34/42? I doubt there are many people with that setup. It'll be the perfect FD for a Gus/Susie with a 34/24 double wrapped around huge tires.
If there's somebody out there running an XD2 triple with two rings and a guard, then that person maybe has a 40/26 or something on their Roadini. If that person has no front derailer, then they might indeed have a hard time getting this one to pull the chain to the small ring. Anyway, I will give it a look on my Black Mountain Monster Cross, which will have a 38/24 double on it soon. I've got a few different FD options for that setup, and I'll give the skeleton key FD a look as I dial it in.
