I'm about your height. I ride the Salsa Vaya for commuting and we plan some short tours in the future. It would do great as a cross bike at least IMHO. All my bikes are 47 cm or less but the Salsa is a 50 cm and fits great. The shop included custom fit with the purchase which really dialed it in. It's affordable, under $2k anyway. Knott has almost the same bike and hers was a little less because they had a sale on the last of the model. Great bike.
