I would like to know if anyone out there has weighted their crank and what amount is good. I ask because i would like to tame the beast a little and THINK this would be one way to accomplish this. I seem to go through rear tires like crazy and think its due to rear wheel spin. I use the word think because im not too sure. I ride desert mostly. PS would the rekluse clutsh help put more usable power to the ground as well? looking for answers.
