What kind of drink is in your water bottle? For me it's always been just water.

Always just water when I commute. For my big trips (daylong/overnight excursions) I will sometimes bring along some Gatorade, but just because I feel like I'm sneaking a treat!

Always water when commuting. When on longer rides I usually pass the mall which has a vending machine with Gatorade and I will fill my, by then, empty second water bottle.

Water.

But I keep several 60ml Nalgene bottles with pre-measured Gatorade crystals in my trunk bag. If I want to go for a longer ride on the way home I just dump one in and give the bottle a good shake. A sign of a good ride are white salt lines running across my jersey and gritty feeling temples. Gotta replace those electrolytes.

For commuting, water.

Good old-fashioned water.

I use water...if I'm going a long way sometimes I'll toss in a little salt...errrrr..."electrolytes" into the second bottle with a little lemon juice and sugar.

water

water for less than 2h trip. More than 2h trip I do my own gatorade : filtered water, salt, honey, vitamins B1..B12, lemon juice

these last few days there is water on both sides of the bottle.

I tend to put a little Mio in the water,...just to add some taste. But, that's about it. I've yet to do a 2+ hour ride,...

water in big bottle, smaller one gets power aid.

Water for length of ride.

I'm surprised that so many people use them for water. Actually I thought for sure someone would say they put coffee or something in theirs.

Green Tea bag and cold water. If in the afternoon or night, plain ol water. Always in a Polar Bottle. But guess that is another thread, what do you put your water in.

Well.... the white one in my avatar had 3 tire levers, some glueless patches, and a Park MT-1 multi-tool at the time.

Dihydrogen monoxide in one. The other usually just has water.

mold.

Water. If I plan on riding 100 miles plus I buy a small bottle of powerade ad I tend to cramp up at 80 miles without more electrolytes.

Water.

I'm concerned about sipping sugary drinks over long periods, and the effect it would have on my teeth, so water only.

On the odd occasion I have something else in another bottle with me, then it gets washed down with water afterwards.

tap water

be careful that stuff is deadly

water on commuting. Longer rides may be a little different.

I prefer Dihydrogen monoxide mixed with Oxygen hydroxine.
