Some riders just have sweaty hands and, when you're one of those riders, you might just want to pick up some Ethic foam grips. While they're not nearly as durable as rubber grips, they're about a quarter of the price. So, if you need more grip due to sweaty hands, pick up a pair of Ethic foam grips. Ethic scooter grips are 6.7" PRO SCOOTER GRIPS. 6 inch grips are a pretty standard grip length that will fit just about every scooter bar on the market. As bars get wider, so do grips. If you have 24 inch wide bars or wider, you may want to pick up the Ethic foam grips, as they are a little bit longer than your standard 6 inch grip and will give you more to grab when you are perfecting that bar spin.
