I'm getting a Long Haul Trucker in a few weeks, and next year I want to really get into long distance cycling. I've done 6 50+ mile rides, 5 62+ mile rides, and 2 centuries this year, and I plan on doing a heck of a lot more next year, along with my first 200k.
My biggest issue is water. I'm a heavy guy and I sweat a lot. I wager my slower-than-average speed also contributes to a higher water-per-mile consumption rate than usual as well. In the peak of summertime, I would need to carry 5x24oz water bottles with me for a metric, and would end up refilling all of those at a gas station for a typical metric century. During fall when the temperatures fell to the 60's my consumption dropped off dramatically and I can now do an 85 miler on 2x24oz water bottles.
Regardless, I've been thinking of alternative methods of carrying water. Carrying 5+ water bottles gets annoying because I've got to continually stop, get off the bike, and rearrange the bottles every couple of miles. For the new bike at first I was thinking of getting a front rack and rigging up some bottle cages on the fork somehow, so that I'll have 4 bottles within reach. Unfortunately that doesn't seem like a very sturdy solution, and I'm thinking I'd rather avoid bottles.
The Camelbak concept is interesting but I've never been able to use those as I sweat a lot and carrying multiple litres of water on my back would only exacerbate the problem. But then I ran into an idea on a mountain bike forum: frame bags.
Specifically, I'm thinking of getting a Revelate Tangle bag, and stuffing a water bladder into it. This seems like a great idea, that way I'll never have to fiddle around with separate bottles, I just have one giant reservoir of water. I see that people can fit the 4L MSR Dromlite bag into it just fine, and that's about 5.5x24oz bottles.
Does anyone have any experience with this method of hydration? Anyone know if the revelate design can possibly hold up to 6L (I'd be getting the largest version of the bag)? Anyone have any better advice?
