Fast Urethane, Sharp grippy lips and Amazingly smooth slides when you kick out the tail. The 70mm RFW Slalom longboard wheel from Sector 9 has all that. These wheels will help you rail those corners when you need it the most, but they will let you shed some speed when going into a corner too fast with a smooth speed check.The smaller contact patch means these wheels will give you a chop free slide when you get sideways. If you aren't the racing type, this wheel will still shred oh so hard on your everyday board! This wheel is made of 'win'.Grab the 78a duro for you're a lighter rider looking for smooth and fast rides or grab the 82a duro for those heavier riders or for all you free-ride enthusiasts out there! Can't decide between the two but know you like the color blue? You know what to do!
