Razor Fz 2000 20-Inch Freestyle Bike

First, the Razor is a beginners bike and if you need tensioners you are probably too advanced for it.

Second, saving 5 to 10 pounds off your bike is almost impossible unless you want to do a complete rebuild... this will cost at least triple what the bike originally cost. The easiest (and cheapest) way to save weight on this bike is to get rid of it and buy another bike at a bike shop
