Anyone tried one of these?
Does not work with all/most bottle cages, but might work for one of the old school nylon cages by profile design.
I actually have a Specialized 1L bottle that I bought from Excel several years ago (with Excel Sports logos on it), same look/feel as the specialized 22 oz purist bottles I have. Only downfall is it does not have the narrow mid-neck to secure it in a water bottle cage. So Specialized has made these in the past although maybe not to exacts specs as would be wanted.
Does it look like this?
My concern with that shape is that it would bottle cage. Have you tried it for that?
Whatās with Specialized Watergate versus Fixy versus MoFlo caps?
Is Fixy their answer to Camelbakās jet valve but without a lockout?
I just had a Watergate valve pop completely out of the cap and splinter into pieces inside the bottle.
Wish I had known that before I took a few swigs. 
Hey Alex, Iām in the market for some new bottles. When do you anticipate your video will drop?
On another note. If youāre only aiming for 90g per hour does it make any sense to do 1:0.8? If weāre to believe itās a max of 60g of malto per hour then economically speaking it makes more sense to do 60/30 maltodextrin/fructose. Iām in instances where itās less than. 90. Day 70. Should we do 60/10?
Thanks!
Loving the app.
I can barely stomach the sweetness of 15g of fructose. 
When you say economically, do you mean $$? Or do you mean some sort of physiological economics/efficiency?
If $$, then use sugar. 
I wouldnāt risk 60g glucose with only 10 fructose personally.
Rationale: why be so close to upper glucose tolerance limits with so much head room for more fructose inclusion?
There are dozens of arguments in either direction. Would take an hour to go through them in all their nerdy fashion. Maybe Iāll make that a giant monologue yt vid. Likely to be viewed by exactly 5 people.
not as soon as Iād like. #appdevlife.
Price. I can barely stomach the sweetness of 15-30g of fructose let alone 90g of sugar. . On another note, my drug of choice was isomaltulose, until it went out of mass production. Even more tasteless than Maltodextrin and apparently a slower release.
Got it!
Iām honestly perplexed why your videos donāt rank higher in youtube. I must have searched and watched every video on the topic for weeks if not months before your video popped up as a suggested watch. Low and behold, a month later and I found you on here.

I feel you. 2 X watter bottles were the biggest upgrade I made recently. Elite Jet 950ml:

Good question. I have no hard evidence. Only anecdote. Several folks who report GI issues more prominently when fructose is largely absent. Especially hovering around the 60g/h mark. Most common offenders: Tailwind, SIS. High glucose inclusion, low fructose inclusion. In SIS case, it may also be lack of sodium in SIS GO Energy.
What if you were one of the five people?
Glad you think theyāre useful! Someday the algorithm may reward us. Just need higher production frequency and quality, I bet.

Have you been able to find information about the exact glucose:fructose ratio for Tailwind? Iām assuming since dextrose is the first ingredient and sucrose is the second ingredient, that itās at least 3:1. Sound right?
I have no exact info for tailwind. All companies Iāve messaged have stonewalled on that front, unless itās in their marketing in the first place. So I havenāt contacted further.
Dextrose, sucrose, as ingredients 1 & 2, respectively, means that it could be 50-50 between the two products, or it could be more like 95-5, if there are no other carb ingredients listed. If itās 50-50, that gives a 2:1 gluc:fruc ratio. If itās almost exclusively dextrose, then well, it could well be 50:1 gluc:fruc.
My optimism says it might be 2:1. Sucrose is cheaper than dextrose, so thatās what Iād do if I were them, and I were going to list dextrose then sucrose.

Very much appreciate you asking, and even if you would ever like to be contrarian, I absolutely welcome it!
Answer:
Just to keep risk lower. I donāt see issue for a lot of folks at 120g/hr when things are managed well. But it does increase risk of mismanagement.
If ceiling consumption is 60g glucose per hour (itās a smidge higher for a lot of folks), then when they get dehydrated, the gut may tend to lower that ceiling and revolt at lower glucose consumption rates. Same for if they go well above threshold. Gut sensitivity increases. Same story for fructose.
I generally just try to keep folks away from the ceiling as a gut safety preventative measure.
Getting way down in the weeds here, thereās also the argument that it might be optimal to include a bit of fructose at lower carb intake rates because folks are likely experience more pulsatility, stochasticity, or volatility, whatever you want to call it, in their blood sugar when flirting with lower intake rates while using only the fastest absorbing carbs. The ādownā phases can sometimes feel kind of crummy if there are large time gaps between consumption.

Thanks for the reply. As athletes become more knowledgeable, companies are going to have to be more transparent, I think. I was interested in Tailwind because the price per gram carb is about as low as I can find aside from homemade solutions, and theyāre from my hometown. If dextrose is 100% glucose and sucrose is 50% glucose (correct me if Iām wrong), then I would think that 3:1 is the minimum possible ratio with dextrose listed first.
