TECHPULLEY, YOU ASK?
From one of the inventors of Dr. Pulley comes the newest and most innovative line of rollers to hit the market.  Tech Pulley's prodcucts are out of Taiwan and are considered the best, esepcially for those truly into unique performance modifications. 

BENEFITS OF TECH PULLEY FLYING ROLLERS:
--The elastic force of the Flying Roller makes it move faster than stock rollers.
--The range of gear ratios are much broader than stock rollers.
--The low gear range is much lower to get better acceleration
--The high gear range is much higher to achieve higher top end speed
--Take-off RPM is about 400~600 rpm higher than stock rollers
--Top end RPM is about 400~600 rpm lower than stock rollers
--Higher quality and more durable than stock rollers

CHOOSING A FLYING ROLLER SIZE: 
--Lighter roller weights will give more climbing power at the consequence of losing some top end speed. 
--Heavier roller weights will allow more top speed at the serious expense of climbing ability - but are great for flat-ground racing.
