Small Frame - no room for 2nd bottle cage

[tealtreak]

I don't have a small frame, but I've tried to use a hydration pack on a road bike, and found it quite uncomfortable. In a more upright position--mountain bike or hybrid, it's no problem.

It might be the type of pack- I ride in the drops- (belly to bar) all the time- especially down hill (FUN) and mine is comfy (: There are many styles/sizes/shapes (:

As far as hydration pack ... I don't like to wear them on the bike either, but on the road bike, I let the shoulder straps all the way out and let the waist strap support the weight of the water on my hipbones. That's the only way I can wear it without straining my back. If needed, I CAN ride all day like that.

Nathan makes a hydration vest for MTB. I have no idea what it's like, but their running vests are EXTREMELY well balanced and comfortable, if that's any indication.

As far as triathlete water systems ... what about one of those frame mounted wedges with the straw? Expensive, but no more than a wearable pack. Would that leave you enough room for a second bottle on the seat tube?
