DIY Front Fork steering stabilizer?

Hi guys,
I'm thinking of getting a nice rack this year and need some ideas on how to stabilize the front fork. Civia bikes has these stabilizers like motorcycles use.
I 'm looking for some DIY ideas. I have a nashbar alu frame so my downtube is kinda thick. I *think* I''ve seen springs like door springs at the Home Depot.
Here's a picture of what it looks like

astrodaimler: Velo Orange has a wheel stabilizer which fits up to a 1-3/8" downtube - http://store.velo-orange.com/index.p...tabilizer.html It even has a little wheel to adjust the tension.

Hey, that's pretty cool. Out of stock but I'm sure it'll be around later this year. I think my downtube is much thicker. Cheapo Nashbar alu touring frame. What would you do to make a round clamp like that?

No that it matters much for this discussion but that's not at all like what motorcycles use. Motorcycles use steering dampers, which have no spring or centering force, only viscous damping provided by fluid passing through orifices in a piston.

You are right Looigi but it was the only analogy I can make.

astrodaimler: I found an earlier thread on the subject; Hebie makes one for up to 62mm downtubes. Scroll down to post #19. http://www.bikeforums.net/showthread...ipod-kickstand

No that's incorrect, they use them to stabilize the parked bike with a loaded front basket.

Velo Orange sells some , goes with the 2 legged Prop stand.
so the load in the basket won't swing off center
and drag the whole bike down with it..

Hebie also makes 2 legged kickstands for cargo carrying bikes.

as with that picture , drill a hole, put a riv-nut in it .
to have a place to bolt onto, then fix one end of the spring there..

This seems to be a complex version of the old "Flickstand" front wheel immobilizer but they won't work on large downtubes.

However, wouldn't a bungie cord wrapped around the downtube and through the front rim do the same thing at much less expense and effort?

So the spring won't actually don't do anything while you are riding and making turns? I'm familiar with the kickstand. Had plenty. But won't the spring expand as you turn the fork?

That's exactly what will happen. But the spring is designed to stretch.

I guess the amount of force needed to hold the fork steady for parking is insignificant compared to the force needed to turn the fork while riding.

I like that idea and I'm going to use it! This bike needs it, but I don't like the plastic clamp on the Velo Orange stabilizer. A rivnut will make it a much cleaner installation.



It almost fell over with a load of fruits and vegetables in the basket, but I caught it.
