That Crane should handle a 14-28 just fine, and I'd bet that most of the 5 speeds in your co-ops bin 'o freewheels are 14-17-20-24-28. Even with the triple, as long as your big ring isn't ridiculous and you're willing to accept a slack chain in the 14/granny. My Fuji (which I'll have back next week!) runs a 45/42/30 x 14-26 no prob, and that's with the notoriously stingy 1st gen Suntour Superbe out back. (23t max, 23 wrap).

And what crankset is that, anyway? I've never seen a hidden-arm 50.4 before. Super neato.
