The new and improved Vanilla Duo Bar has been developed alongside professional cycling teams to replicate the rice cake concept used in World Tour races. Each Duo Bar is pre-cut into two equal pieces with each piece delivering 20g of carbohydrate. This makes the Duo Bar very easy to use as part of our OTE Energy System. The Duo Bar has been designed to be great tasting, easily digested and light on the stomach. A great solid food alternative to energy drinks and gels. Also, our Duo Bars are now gluten free! Every batch of this product is tested for banned substances under the Informed Sport programme. Products undergo rigorous testing using ISO 17025 accredited methods to provide the highest level of assurance for athletes.
