I always now wear a Camelbak on both my road and mountain bike. No more having to reach down anywhere. The nozzle is right there and I can grab it without taking my hands off the bars (Although I usually use my left to grab it). I find I drink more wearing a Camelbak. They make pretty small ones for road bike use if you dont like carrying the weight on your back. You can then carry a water bottle and refill the Camelbak when it's empty (if there is no other water source nearby).
