SiS Beta Fuel for Cycling Your New Endurance Edge

SiS Beta Fuel’s new 1:0.8 maltodextrin-to-fructose ratio enhances carb absorption. Designed for elite cyclists needing 80-120g carbs/hour with no stomach upset. This guide breaks down how, why, and when to use Beta Fuel for best results.

Why Nutrition Is Just as Important as FTP

You can invest in the lightest carbon bike or crank out intervals to raise your Functional Threshold Power (FTP), but none of that matters if your body runs out of fuel halfway through a ride. Nutrition isn’t just a supplement to your training, it's the foundation.

In endurance cycling, your body relies heavily on carbohydrates to sustain performance. And while the average cyclist stores enough carbs for up to 90–120 minutes of effort, longer sessions require strategic fuelling to prevent fatigue.

That’s where SiS Beta Fuel steps in.

What Makes SiS Beta Fuel Different?

The upgraded SiS Beta Fuel range utilises a 1:0.8 ratio of maltodextrin to fructose, a shift from the traditional 2:1 formula. Why the change?

• 17% boost in total carbohydrate oxidation.
• 3% higher mean power output during sprint efforts.
• 74% oxidation efficiency vs. 62% from the 2:1 ratio.
• Fewer reports of bloating, nausea, and stomach issues.

This isn’t marketing fluff. These are peer-reviewed findings that reshape how we understand carb fuelling.

The Science Behind the Carb Ratio

When carbohydrates are consumed during exercise, their absorption is limited by how fast they can cross the intestinal wall. Glucose (from maltodextrin) and fructose use different transporters. Combining them allows for simultaneous absorption, increasing total delivery without overloading your gut.

Beta Fuel leverages this principle in a scientifically optimised isotonic formula meaning you can take in more carbs without GI distress.

How Much Carbohydrate Should Cyclists Consume?

For efforts over 2–2.5 hours, current guidelines recommend 80–120g of carbohydrate per hour. However, traditional fuelling approaches rarely reach the upper end of this range often due to gut discomfort or lack of variety.

SiS Beta Fuel makes it achievable by offering:

• Powders (80g per 500ml bottle)
• Gels (40g per sachet)
• Chew bars (45g total, ~7g per chew)
• Nootropic-enhanced gels (40g per sachet)

Here’s a sample fuelling plan for a 3-hour ride (target: ~240–360g carbs):

• 1 x Beta Fuel Drink (80g)
• 2 x Beta Fuel Gels (80g)
• 1 x Chew Bar (45g)
• 1 x Nootropic Gel (40g)

Total: 245g, comfortably within target range.

Personalising Your Beta Fuel Strategy

Every athlete is unique. Your optimal fuelling rate will depend on:

• Body weight
• Training intensity
• Gut adaptation to carbs
• Personal flavour and texture preferences

Tip: Practice your nutrition in training, not on race day. Build up gradually to the higher carb targets.

How Beta Fuel Supports Performance

1. Higher Energy Availability

Even after 3 hours of hard riding, athletes using Beta Fuel derived 50% of their energy from it preserving muscle glycogen.

2. Reduced Fatigue and Perceived Effort

The consistent carb supply maintains blood glucose and lowers perceived exertion.

3. No Gastrointestinal Distress

Thanks to the 1:0.8 ratio and isotonic formulation, even high intake levels were well tolerated.

4. Cognitive Edge

Beta Fuel’s Nootropic Gel option helps maintain focus and decision-making during the later stages of intense efforts.

Level Up Your Performance With Science-Backed Fuelling

SiS Beta Fuel isn’t just a nutrition product it’s a performance enhancer rooted in research and elite testing. Whether you’re tackling a gran fondo or a structured interval session, strategic fuelling makes the difference.
