What you want is a testosterone patch on your testicles instead of creatine. That method comes right out of the Tour de France training manual.

In all seriousness, I've used creatine when lifting. While I felt results, I'm not entirely convinced that it wasn't just mental. It is true that dehydration can be an issue, so if you choose to go that route, carry plenty of water when riding. I've tended to stay away from it during the cycling season due to this. As far as increased energy levels, I can't say that I noticed that from creatine. However, I tended to use just creatine, not some of the supplement combinations that are being sold by Met-RX or the similar companies. Many of those are also high in sugar or caffiene to give that energy boost.

In regards to pumps, I had that little Crank Bros. deal that came with the pressure gauge. While repairing a flat on my road bike, I managed to rip the Presta valve apart while attempting to use the pump rendering the new tube useless. I have since switched to a CO2 setup. I do think the Crank Bros. pump would be fine on a Schraeder valve and therefore carry it in my Camelbak when on the trail.
