| 1985 | ACS Rotor A guy nobody has ever heard of, Dale Cooper, invents a little machined aluminum thing that attaches to your stem and allows for tangle free rearbrakes. ACS markets this as THE ROTOR. BMX Action may 1985 : A couple days ago. Dale Cooper, who works down at Riverside Schwinn (over in Riverside, California), called and said he wanted to bring down his new invention for a quick preview. We yawned, scratched our heads, and finally told him to come on down. When he showed up with a Potts Mod that's built for REAR calipers, our jaws immediately dropped into our laps. Think of it! Put the Dale Mod (which is the name everyone around here has tagged onto it) together with a Potts Mod for your front caliper, and it's possible to spin the bars around FOREVER without kinking the cables. This is the best news for hard-core freestylers since the invention of the quarter-pipel So how does this deal work? A two-piece aluminum pivot is the heart of the whole thing. The top piece has a tube that runs down through the inside of the bottom piece, and the whole thing is held together with a snap ring. That means the two pieces are connected, but can easily turn independently of each other. Now the other interesting thing is that there are two sections of brake cable. The first one runs from the brake lever to the top half of the aluminum pivot, and the second one starts at the lower halt and runs to the caliper. Now check out the photo. See how the anchor attached to the stem's wedge bolt catches the end of the upper cable housing? And how there's another anchor on the top tube for the lower cable housing? That's so the whole aluminum pivot can move up and down to activate the rear caliper AND still pivot for days on end. Braking performance is every bit as good as normal. The only drawback to the system is that you have to run the stem about an inch higher than normal so that the aluminum pieces can slide up and down the stem shaft. No real biggie. Right now Dale is working with ACS on gettin' these guys into production, and they'll have a complete kit available by the time you read this. The kit will come complete with an ACS stern, a Potts Mod bolt for your front caliper, and all the goodies necessary to set up the Dale Mod. Right now it looks like the whole package will go for right around 40 frogskins. Bitchenl |
