I love SiS Gels, as they are easy to consume whilst riding and give you an instant boost in energy. I use them in conjunction with Go Energy Powder and alternate between Gels and SiS Energy Cakes when on long rides. This ensures I get the energy to sustain my ride and stop me from bonking, as I have done in the past.

Great as a booster when you are feeling like the energy reserves are getting low or you know there is a bit of a nasty one in a few miles. It gets I to the system swiftly and no need to worry about hydrating as well.
