Building a rigid 29er Fork

[Tankman]

With my last SS project, I decided to use as much parts I had lying around instead of buying new stuff.

 

The main component I needed was a fork.

Luckily I had lowers and stanchions from a busted Fox and came up with the idea to convert it to a rigid fork using threaded rod, washers and nuts.

 

This is what I did, it works perfectly and cost me only R47 all in!

 

Stanchions:

 

Busted lowers, cant hold air or oil:

Washers, same size as the stanchion:

 

measured out the correct length

 

Stanchions push down on the washers so there is no travel:

bolts on the inside and outside of lowers:

 

washer on top with locknuts:

 

I did change all the nuts to locknuts in the end

Nicely done.

The word is Stanchion/s, not Sanction/s.

Great idea. I would use stainless threaded rod because a big hit might cause them to bend under the pressure. Threaded rods are made for pulling forces and not pushing in my experiences working with it. we use them to hang large equipment, typically from concrete ceilings, etc.

Perhaps adding a washer that just fits into the lowers with 2 locking nuts would prevent it from bending along that section. Might be overthinking it though......

Yea I gave it much thought also. I recon not much can happen even if they do bend.

If the washers fail, the Stanchions can only move further down into the lowers, until it bottoms out.

 

As long as it doesnt come apart, all is gooood!

If the washers do fail and it bottoms out you will definately know about it.

Still think its a great idea if you have a busted lower like yours. How does it ride? Any noticable vibrations, etc??

It rides awesomely, no vibrations and rock solid!

 

One thing you learn very quickly with a rigid fork ... pick your line fast ... and stick to it!

 

We take for granted what comfort and plushness forks and suspensions offer but you realize very quickly once it is gone!

Haha. Just thought I'd say so, now you'll know for ever. I'm shaping minds, one person at a time...

Know exactly what you mean, been riding a rigid carbon ss for about 2 weeks now, took my other bike for a spin yesterday and it felt like was riding on a cloud lol.

great job.
