The Proto Standard Compression System (SCS) is Patented and the original and first SCS pro scooter compression clamp ever made and is considered the best among many pro riders. Also known as the ‘Knuckle”, this SCS clamp is 4” tall which makes it suitable for pro scooter forks with longer steerer tubes or decks with short head tubes. Ideally, the steerer of your fork sticks up between 1.5” and 1 7/8” above your headset. Proto 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. Proto SCS comes in many anodized colors and is CNC machined in California from 6061 T-6 aircraft grade aluminum. The clamp comes with compression cap, compression bolt, and a 1.125” star nut.
THREADLESS FORKS ONLY! Because of their short steerer tube, not recommended with Phoenix, TILT, Ethic or Urban Artt forks.
Tools: Allen wrench metric # 5, Starnut Setter (selected, mostly steel forks), Ball bearing grease or anti seize compound .
THREADLESS FORKS ONLY! Because of their short steerer tube, not recommended with Phoenix, TILT, Ethic or Urban Artt 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. Proto SCS is 4 inches tall so there is 2.0 inches of space in the clamp for your pro scooter fork which means you want to have 1.5"- 1.75" steerer above headset . If you are not currently using an SCS you will need to cut 2 inches off the bottom of your bars as well to maintain your same bar height and remove the slit.
