The 75mm 78a RACE wheel is a grip monster. It will outgrip any wheel on the market. Once you break the skin, it will slide smooth but have tremendous braking potential.The Powell-Peralta 75mm Kevin Reimer wheel is an ALL-OUT race wheel. It is a new concept on wheel design that features a massive inset lip that will give you huge traction, better wear, and a narrower track width on your trucks. This is NOT for sliding casually, or for cruising the streets – It is for racing World Cup level tracks and taking home podiums.HOW TO RIDE THIS WHEEL:This is not your average DH wheel. It is meant to have tremendous traction when new, and you will not be easily able to slide it. In order to slide the wheel, you should enter the corner as fast as possible, commit to the turn, grab rail, load the wheel up, THEN slide it. If you try to throw a pendulum slide, it will probably buck you off when fresh. This is an ALL-OUT race wheel that is meant to win races, not casually skate down hills. Once the skin is gone, you will find this wheel to slide very smooth, and will grip substantially more than other wheels, even without the skin – this is due to the inset lip. Choose the 72mm Kevin Reimer if you want to slide corners, and do some fast freeride.There is NO WARRANTY offered on this wheel, due to its pricing and usage. Being that is has very thin outboard lips, it is prone to chipping or chunking if slid on rough pavement, over cracks, or allowed to crash into curbs.
