Review: Good coffee taste. - As long as you really like coffee this is the one for you. It will give you that little boost mid ride,you do need to wash it down with a little water as like most gels it sticks in your mouth.
Review: No riders bonking!! - The flavour is like a poor quality cold brew coffee, but the effectiveness with the caffeine was worth it. Helped me to stay alert without feeling wired, and no side affects such as racing heart beat.
