Ninety grams of carbs an hour sounds simple until you try to physically carry that much fuel in three jersey pockets. Enervit's Carbo Bar C2:1PRO is built around that constraint. This oat-based bar runs glucose and fructose in a 2:1 ratio, the dual-carb approach that recruits two separate gut absorption pathways at once, letting you push past the roughly 60g-per-hour ceiling of glucose alone and sustain 90g or more without the intestinal backup that unravels a hard day. A single 45g bar delivers 30g of carbohydrates, so nearly every gram riding in your pocket is fuel rather than filler.

What keeps it settled in the stomach is what got left out. The formula holds fat to 5% and protein under 5%, the two macros that slow digestion, so the bar clears quickly even when your heart rate is pinned and blood is pulled away from your gut. It stays chewable under exertion too, which matters when you're trying to get calories down mid-effort instead of gnawing on something dense and dry. Each bar carries 163 kcal and a dose of vitamin B1 (thiamin), which supports normal energy metabolism.

If you're already fueling with Enervit's C2:1PRO gels or chews, the bar runs the identical 2:1 ratio, so you can build a race-day plan around one absorption strategy from the first climb to the final hour. The line was developed alongside Tadej Pogacar and UAE Team Emirates and is Doping Free certified, which matters to licensed racers who need to account for exactly what they're putting down. This listing is the bag of 5 bars, the way to refill the ride box or pack a weekend's worth without committing to a full 12-count box.
