Buying Guide

  • Carbohydrate content and timing: For endurance rides, aim for bars with 30–50 g of carbs per bar and consider timing around workouts (pre-, during, and post-ride).
  • Carb source: Look for a mix of fast and slow-digesting carbohydrates (glucose, maltodextrin, fructose) to reduce GI distress and sustain energy.
  • Protein and fibre: Bars with protein and fibre support recovery and satiety, especially on longer rides or multi-day events.
  • Ingredients and flavour: Real fruit and oats are common in cycling bars; avoid unnecessary artificial additives if you prefer clean labels.
  • Diet suitability: Vegan, vegetarian, or allergen-friendly options should be checked if required.
  • Portability and packaging: Consider resealable pouches or bars that fit easily into cycling jerseys or packs for on-the-go energy.
  • Alternatives and complements: In addition to bars, isotonic gels or energy chews can offer quick energy bursts during races or high-intensity segments.
  • Energy management strategy: Integrate bars with gels or liquids to maintain carbohydrate availability without GI overload during long rides.
