i would definately try something other than those piece of sh*t rollers, i got a set of double bearing,hard ass black rubber rollers from east coast atv, thinkin they'd be better than the single bearing, pretty color, soft rubber ones the dealers carry, but noooooo, my bottom one wore out in like 4/5 months, bearings falling out, good thing i only paid $10 instead of $20 for the softy's, i did write ecatv, and they told me to send my address, and they'll send me a new set, props to them, but yeah, freeks or tm design sliders for me next time
