Just a follow up on the Vaya. I made the purchase and have put about 1500 miles on the bike. I put nano 40's on it. The bike is very comfortable on gravel and asphalt. The shifting is very reliable, not as smooth as the higher end components but very capable. Thanks for everyone's responses and I would recommend this bike for gravel rides. I'm Kind of curious what a lighter wheel set and narrower tires would do for quicker asphalt ride?
