I just found a few purchase options on Google. How do you like these SIS bottles? Have you tried the Zefal ones? Zefal is all that I’ve used and I’m tempted to try the SIS ones.
How is bottle security? I have had the zefal ones come out of a cage a couple times if I’m not using the best cages.
Cool. Yeah, that’s probably 116.7g glucose and 33.3g fructose per bottle. That assumes a 2:1 gluc:fruc ratio contribution from Gatorade, which is what they’ve marketed. Need more fructose overall.
Great point. I should look into this. 29 cent hamburger Wednesdays were a staple in my household. 
Perfect strategy.
Also this. Great. I did a presentation on “on-the-fly” nutrition decision-making for USA Triathlon coaching education and you’d have made an excellent co-presenter.
Do you have insider knowledge or have you done an analysis? Very interested if so. Curious into your rationale for thinking that Gatorade is closer to 1:1 gluc:fruc.
If I were Gatorade, I’d market 2:1 until the popularity of that dies. But I’d put almost pure sucrose in it because it’s cheaper and more effective, and not tell anyone that it was 1:1.
Do you think that’s what they’re doing?
“2:1” will usually refer to glucose:fructose, and it has been the industry standard “ideal” ratio for 15+ yrs.
For your ratio thinking:
Maltodextrin = pure glucose, just strung together.
Dextrose = glucose.
Gatorade = sucrose + dextrose in undisclosed ratio.
Sucrose (“sugar”) = equal parts glucose + fructose
