Like powerbars, the dog is hard to chew on the bike. If you take of a piece of any decent size you may find it difficult to breathe properly: not pleasant. I solve that problem by slicing it into very thin strips and shoving it all into a ziplock.

Most bars will be rock hard in cold conditions and rubbery when its hot.

I went for the protein/carb ratio. It wasn't until later that I read their lies about all the creatine, ATP, EPO, etc that's in it.
