this is kinda an odd question, so i apoligize for its randomness. I am a college student, and i build a small racecar each year. We are looking to make a steering wheel mounted clutch so the cable needs to twist a lot, but the near by tubes really won't allow this. we are hoping to use a gyro mounted to the steering shaft to solve this. Are there any "better than the rest" gyros out there, or are they all about the same? also, what is the normal ID of the gyro? we use a 3/4 inch steering shaft, so it needs to fit. Also does a heavy duty model exist? we use a rather thick cable because of the stiff clutch, so it need to be strong. Thanks in advance for anyone that has any feedback at all. oh yea, heres the car:

Detanglers come in 1-1/8" inner diameters for the headtube pieces; the detangler itself probably is more like 1-1/4". And the only cables that they accept are normal brake and derailleur cables for bikes.

The best detangler out there at the moment is the Odyssey Gyro GTX (or the GTX-R, which is aluminum instead of steel).

If a BMX gyro doesn't work couldn't you just make one? I mean, you can make go-carts and stuff, just take the deseign and make it thicker and make it fit the cables you need to fit in it. Just a thought.

I would think that you can get an aluminum gyro GTX and machine the openings a little bit wider without any repercussions. The Gyro, if you look at the way it works, actually free floats on the head tube. It is not connected to anything, so the main thing you want is for it to be larger than the tube it is going around.

You will have to work out an upper and a lower cable stop though.

Look at the photo below and you will see 5 distinct parts...
an upper cable, the upper plate, the actual detangler, the lower plate, and the lower cable

good question, when was the gyro invented? i googled it and couldnt find much on it

[BMXTRIX]

Either late 85 or early 86 by Brian Scura. The ACS Rotor actually was invented first and was the first detangler, perhaps as early as 84, but really, the Oddysey Gyro was soon thereafter and is what is most common today.

thanks for the feedback. i guess once i have one in my hands and im playing with it, it will all be clear.
