Hi, I am new to this site and adventure cycling. I was always a roadie, but now live in AK so am expanding my biking to loaded touring. I'm short (ride a 48-49 cm), so I'm limited in my bike choices. Locally, I can order a 2013 48 cm Trek 520 or buy a 49 cm 2012 Kona Sutra in stock. My plan is to commute and tour on the same bike. I test rode both (I had to test the 520 one size up.), and liked each for different reasons: The trek was fun and zippier, and the Sutra was solid, stable and bombproof. I'm not concerned about the v-brake vs. disc-brake difference, but I am a little concerned about the weight of the Sutra. Any thoughts on the versatility, durability and reliability of each of these bikes? Any recommendations? Thanks!
