Compare SIS GO Plus Isotonic Energy Gel and SIS Beta Fuel + Electrolytes Gel to decide which fuel suits your ride length and intensity.
Quick answer
For rides under two hours, the SIS GO Plus Isotonic Energy Gel provides fast, no-water-needed carbs. For longer efforts, the SIS Beta Fuel + Electrolytes Gel delivers dual-source energy and electrolytes to sustain performance.
Carbohydrate source and timing
The main difference between these two gels lies in their carbohydrate composition and how your body processes them. The SIS GO Plus uses a single-source carbohydrate designed for rapid absorption, making it ideal when you need a quick energy boost without carrying extra water. In contrast, the SIS Beta Fuel + Electrolytes Gel uses a dual-source carbohydrate blend that delivers sustained energy over a longer period, which is why it's formulated for activities lasting more than two hours.
Electrolyte content for hydration
Electrolyte needs become more critical as ride duration increases. The SIS Beta Fuel + Electrolytes Gel includes 200 mg of sodium per gel, which helps maintain fluid balance and reduce cramping risk during extended efforts. The SIS GO Plus Isotonic Gel does not list a specific sodium content in its standard formulation, so riders doing long hot rides may need to supplement electrolytes separately if they choose the GO Plus.
Trade-offs at a glance
- SIS GO Plus Isotonic Energy Gel: Best for rides under two hours or when you need immediate energy without extra water. Single-source carbs absorb fast.
- SIS Beta Fuel + Electrolytes Gel: Best for rides over two hours. Dual-source carbs provide sustained energy, and 200mg sodium supports hydration.
- Cost per gel: The SIS GO Plus is priced at $2.99 per gel (regular $3.99), while the SIS Beta Fuel + Electrolytes is $3.87 per gel (regular $5.45). If you ride long distances regularly, the Beta Fuel's extra cost may be justified by its electrolyte and endurance benefits.
Product facts
- SIS Beta Fuel + Electrolytes Gel: Contains 40g of carbohydrate and 200mg of sodium per gel. This dual-source carb plus electrolyte combination supports hydration and energy for rides longer than two hours.
SIS Beta Fuel + Electrolytes Gel - SIS GO Plus Isotonic Energy Gel: World's first isotonic energy gel, designed to be consumed without water. You can take it mid-ride without stopping to drink, making it convenient for quick energy top-ups.
