You just ordered a smallish Rivendell frameset and don't have a crankset picked out. All you know is that all the Rivendell Silver models are sold out in the shortest 170mm length. Bummer!
Well, I just parted out a small Rivendell, and so I've got a 170mm triple crankset available. This one is kind of extra special in Riv-Street-Cred, because it is not 44/34/24 like the current Rivendell triple. It's got the rings of the original Rivendell Silver offering: 43/35/24. That's super weird and awesome. Nobody will know, and you'll forget. Riv themselves know it doesn't really matter. They did odd chainring sizes just to be different.
Wait for the next shipment of Silver cranks and pay $250 (or whatever they actually cost) -OR- buy mine for $200 shipped in the US.
ALSO, if you have a Riv Silver crankset in 173mm and just want to trade arms for arms, let me know and I'll do that.
