Does the trick and no stomach upset like with some gels. Not too sweet, Will buy again.
Great flavour, easy to digest, a must on longer rides. Great price from Merlin, as ever
I think they're the best gels. Taste great, no need for water and not overpowering. So easy to use.
Been looking at these for a bit now as l have been getting a lot of miles in so l bit the bullet and brought some l cant recommend then highly enough went out and dome over 30 miles on my bike this just give you that boost you need to get back home
Easy to swallow and take even when breathing hard in a fast working peloton. Does not lie heavy on the stomach and no need for water to wash it down. Effects can be felt from about 5 mins after consuming. Gives you that boost required to win.
I have found these to work well when you get to the point that you could do with a boost. Usually around the 30 mile point for me. They are easy to digest and work quite quickly.
You've cycled 30 miles, and faced with tired legs and 20 miles to go, decide on an energy boost. This SIS Isotonic Gel does the job, and within 10 minutes of taking, gives you an incredible extra burst of energy. Well recomended!
Taste good, easy to digest, faffy opening tab
does what it says on the packet
I find these great for a 20-30 minute energy boost. They're not too thick and I really like the tropical flavour, although I'm not sure what its based on.
