The SiS GO Isotonic Gel was the world’s first isotonic gel effectively delivering an easily digestible and quick supply of carbohydrate for energy during exercise. SiS GO Gels are designed to be consumed without water meaning that you can ensure rapid delivery of carbohydrate to your muscles without the feelings of being bloated that can sometimes occur with over-drinking.

Depleting your carbohydrate stores during exercise is one of the major causes of fatigue. In addition to ensuring optimal carbohydrate stores before exercise, delivering additional carbohydrate during exercise is known to improve performance, race times and delay the onset of fatigue.

As such, SiS GO Isotonic Gels represent a highly practical solution to your in-training and competition fuelling strategy by providing you with a quick supply of 20 grams of carbohydrate per gel. Gels can easily be carried in your pocket or your race belt without the requirement for bulky bottles.

Key Features:

  • 20 grams of carbohydrate per gel
  • Isotonic formulation delivers energy fast
  • Convenient gel format
  • Recommended Usage: Consume 1-3 gels per hour to deliver approximately 60 grams of carbohydrate and maximise carbohydrate utilization rates. Where hydration is also important, SiS GO Isotonic Gels can also be consumed with SiS GO Hydro or with SiS GO Electrolyte to ensure a combination of both energy and fluid delivery during exercise.

SIS gel packs

great stuff, goes down easy, easy to carry in a jersey pocket 10 or 20 at a time no problem, I am an old school cyclist use to race semi-pro in the late 80's early 90's and mainly raced on bananas and muffins and the odd chicken sandwich, since I tried sis gel packs I will not go back, I have a huge event coming up in august at Trois Riveriere Que, a grand fondo, 73 miles(118km) and all I will use is a banana , water and SIS gel packs.

SiS Gel

These a good gels for racing, they are easy to open and go down easily. They are not thick at all which is good if you cannot stand the taste of some gels. They are rather big sachets though. Would use again.

Great Quality, Great Value

From all the different brands & types of Isotonic gels that I've had in the past, these are my favourite & are great value. Great range of flavours too :-)

Excellent Fueling

SIS is always same quality and easy to use without water. Its my first choise for years now.

One of the best

Have tried a number of gels however the SIS Go gels are one of the best given they do not have an overly strong taste - which is not what you want when trying to get a gel down while under pressure. As they are isotonic they don't have that overly gluggy feel that you get with most gels. I highly recommend the lemon/lime flavour or pink grapefruit.

Poor service

The product is great and really good value, however its only good value when you buy it from another supplier other than PROBIKEKIT, ordered and paid for and still waiting 7 WEEKS later, I've since bought the same product cheaper elsewhere and given up on ever seeing anything from these jokers

They're energy gels!

If you don't like the really thick ones or the really runny ones - these are great.

Isotonic Gels

Have used these Gels in the past and was always unsure if they really worked. I was proved very wrong. I always enjoy the Challenge of Hills. I was amazed how they gave me the extra boost when needed. Granted my fitness has improved and I'll never be a Bradley Wiggins or Chris Froome but they do help.


Great stuff, gives you a boost as needed, easy to use. I don't leave home without them now.

Great gels!

Been using these for a while. Just the job for running and cycling. One of the few gels I can get on with when changing from bike to run on duathlons. The probike kit offer was a no brainer and I've stocked up!
