I take one about every hour on an epic ride. Really does work, no Charlie horse cramp during or after an epic ride. Helps me keep up with my buddy, Dan, who is half my age and a road bike rider (we Mt. bike together). I wish they were a little less expensive, but I keep buying them because they work.
Gu Roctane is by far my favorite energy gel for cycling. They are easy to use and I like the flavor. The caffeine gives me the boost I need and the other ingredients provide great fuel for long rides. Overall I am very pleased with this product. I feel that it is worth the price
I love GU products for energy drinks and gels. I usually use the regular gel but Roctane gives me an extra boost for long andor hard rides and for pre-race. The gel is easy to digest and none of the flavors are overly sweet.
I have been using Gu Roctane for many years. It is great fuel for when I'm on the bike...definitely feel the difference after I take it. I've tried other products, but nothing measures up to Roctane. Only mild drawback to this product...it is very sticky...try not to get it on hands...,-)
