Description
SIS Caffeine Gel – a kick when you need it
The SIS Caffeine Gel pairs 22 grams of fast carbs with a dose of caffeine. Berry has 75mg, and Double Espresso has 150mg. So you get fuel for the legs and a lift for the head in one gel.
Caffeine lowers how hard an effort feels. As a result, it is a popular choice for race starts, hard intervals and the last hour of a long day. Also, the isotonic gel goes down without water.
Key features
- 22g of carbohydrate per gel
- 75mg (Berry) or 150mg (Double Espresso) of caffeine
- Isotonic, so no water needed
- Use before or during hard efforts
- Box of 30

Who is the SIS Caffeine Gel for?
It suits racers and riders doing hard sessions. Take one 30 minutes before the start, then another late in the ride. Because caffeine affects people differently, try it in training first. Also, use the standard GO Isotonic gel for the rest of your fuelling.
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.
