I doubt that anyone on this forum would know. You could email the manufacture to ask for the cage length.
With 11-42t you still only get 382% range. A double chainring could get you over 500% depending on how you set it up.
For example 52/34 and 11-34 gives you 472% if you're willing to setup an 18t double jump. Or 487% if you use a 33t inner chainring 110bcd. 130bcd minimum is 38t. 74bcd minimum is 24t.
