I keep a tube, multi tool in a small seat bag and I put everything else in the Camelback. I can never seem to get a drink when I want to with a water bottle and the CB just makes it to easy and convienent to keep hydrated throughout the ride. I have had to stop more to get the water bottle because of trail conditions and wouldn't want my hand off the bars for to long, but on a road or straight away it wouldn't be so bad.
