The Razor IV PB shocks are for those who really know and care enough about suspension to adjust them nearly every time they ride. Based on your use, the Razor III would be a stellar choice, and arguably the ride would not be better than the PB versions, for how you use your bike. Set and forget outside of spring preload based on your carrying load. Both versions have tremendous available travel, and superior damping over stock. TIA for the purchase.Right, I understand that any of these aftermarket shocks will be much better than the oem ones. My question was about the difference between nice regular twin shocks and nice ones with PBs. I'm not heavy (165 lbs) buy I do plan on doing a bunch of travel and camping with luggage so it won't always just be me.
