I cut my energy bars up in bite size pieces and drop them in the back pocket. However body heat & sun turn them into a sticky mess which gets tranferred to bars, brake levers etc. :'( Solution is to wrap them in rice paper. Cut paper to length of bar, run bar under tap, then lay on paper & wrap. Leave for few minutes. Cut to size. I use garden secuteurs, (wife says wash them first! :) DON'T wet the rice paper, only the bar! Fiddly job but worth it. I use PVM bars http://www.energybar.co.za I buy them by the box from Macro which works out at R2-35 a bar. They come in various flavours.
