I'm new to mountain biking and usually go online to find reviews and opinions on everything I buy and usually can make a pretty good decision based on other's comments. I was trying to decide whether to buy a mini pump or CO2 cartridges to take along in my Camelback. More of the responses leaned toward a mimi pump so I figured that's the way to go. I've looked at some like Blackburn and Crank Brothers and people either said they were awesome or complete pieces of junk, there was no middle ground. Any suggestions? Also, has anyone benefited or used creatine as a supplement? I know it's good for lifting weights but just wondered if helped with biking. Thanks for any help.
