The Root Industries Air SCS is brand new on the US market. It comes with Metric 8 bolts for extra clamping power. The Root Industries Air SCS clamp is 3” tall which makes it suitable for scooter forks with shorter steerer tubes. Ideally, the steerer of your fork sticks up between 1.25” and 1 3/8” above your headset. Root SCS comes with a shim so it can be used with both standard 1 1/4" outside diameter as well as oversized 1 3/8" OD pro scooter bars and aluminum bars. The SCS clamp comes in many anodized colors and is CNC machined from 6061 T-6 aircraft grade aluminum. The clamp comes with "vulcano" style compression cap and M6 compression bolt (allen #5 drive).
THREADLESS FORKS ONLY! Because of their long steerer tube, not recommended with District, Lucky, 5Starr, and MGP forks.
Tools: Allen wrench metric # 6, Starnut Setter (selected, mostly steel forks), Ball bearing grease or anti seize compound .
THREADLESS FORKS ONLY! Because of their long steerer tube, not recommended with District, Lucky, 5Starr, and MGP pro scooter forks.
Put grease or anti seize compound on the threads of the clamp bolts and under the head of the bolts! This prevents bolts from getting stuck in the clamp and allows you to tighten the bolts better. This SCS is only 3 inches tall so there is only 1.5 inches of space in the clamp for your fork which means in most cases (except Phoenix, Tilt, and Urban Artt forks) it may be required to trim your fork down so you have 1.25"- 1.40" steerer above headset . If you are not currently using an SCS you will need to cut 1.5 inches off the bottom of your pro scooter bars as well to maintain your same bar height and remove the slit.
