Description
SIS GO Isotonic Gel – the easy everyday energy gel
The SIS GO Isotonic Gel was the first truly isotonic energy gel. Each 60ml gel gives you 22 grams of fast carbs, and you do not need water to take it. So it goes down easily, even when you are working hard.
Because it is isotonic, your stomach absorbs it quickly without pulling in extra fluid. As a result, it is gentle on the gut and a good first gel for newer riders. Also, the box of 30 works out far cheaper per gel than buying singles.
Key features
- 22g of carbohydrate per gel
- Isotonic formula, so no water needed
- 87 kcal per gel
- Eight flavours to rotate through
- Box of 30 for the season

Who is the SIS GO Isotonic Gel for?
It suits every kind of rider, from weekend bunch rides to long training days. Most riders take one every 20 to 40 minutes. So mix flavours to keep things fresh. Also, if you want caffeine or electrolytes, look at the GO Energy + Caffeine and GO Energy + Electrolyte gels. Then for very long days, step up to Beta Fuel.
What’s in the box
Pick your flavour above. The box holds thirty 60ml gels in one flavour. Then each gel is one serve.
A quick fuelling tip
Always test new nutrition in training before race day. So plan your carbs, fluid and salts per hour, then build that plan from drinks, gels and chews. Also, keep a note of what worked on each ride. Then on longer rides, set a reminder on your bike computer to eat and drink every 20 minutes. Because hunger shows up late, fuelling early keeps your energy steady to the finish.
