My wife and I are looking at getting a couple of new Specialized Cross trail bikes for trail riding. Most of the trails we ride are paved. We both have experience with V Brakes but the bikes we are looking at come with ether Disc brakes or the V brakes. My wife likes the color of the bike with Disc brakes, Ha,Ha,Ha. I have no experience with Disc brakes. Any advantages or disadvantages with Disc over V brakes?
