The Proto Gripper Signature Pro Scooter Wheels are the original PROTO wheel, designed to be fast, smooth, and strong, with a spoked core that provides an excellent strength-to-weight ratio. This 2-pack of 110mm wheels is a special Zack Martin "Wasted" signature edition and comes complete with bearings and spacers. Grippers are considered the softer Proto wheel, making them ideal for slippery skatepark terrain while still performing well on rougher street surfaces. These wheels weigh approximately 1.1 lbs and feature a 110mm size with a 24mm core and urethane width. They are made in the USA with an anodized 6061 T-6 aluminum core for durability and include PROTO Murders Bearings pre-installed. A key feature is the BUFF Core Technology, which helps absorb impacts, reduce de-hubbing, and create a smoother ride. All PROTO wheels are manufactured with bearing removal slots for quick and easy replacement. They come with a limited 90-day warranty against chunking and de-hubbing.
