    Has anyone made their own leading link forks? They seem pretty simple. Just wondering if anyone else has already tried it. Thanks!

    There are many that are through out these pages. You can find mine by using "search this tread" using { Dirt Floor Build }.

    When I was building I read every build tread in "HACKS". It took a while but was worth it to have as many ideas as possible to make my decisions from. There is no one right way to do this Hack thing.

    Have fun reading a lot, or have fun learning to read a lot. :huh

    I am still planning on building these bad boys! I'm working on my plans for them and brainstorming as we speak. There are so many great builds on this forum. It has been very helpful. I will post some pictures once I make some progress. I will likley just move this discussion to my build thread. Thanks for all the help guys!

    Lots of home built leading links. Here's a photo of mine when they were nearly finished.

    That was an awesome build.....very inspiring! I'm sure I will have more question down the road, but right now I am wondering where did you get your brake stay rods? I am thinking about using a similar design. I didnt know if you made them or not. Thanks again.

    One other question I have is can a bike with LL forks be ridden solo? If so how does it handle?

    Thank you for the kind words on the build. The 'brake stay rod' assembly are left and right rod ends (heim joints) with radius rods in between. The radius rods are pre-fabbed with female left and right threads. A jam nut goes on each heim joint thread to lock it all in place. Once the jam nuts are loose, turn the radius rod one way and the heim joints thread in making the whole assembly shorter, turn the other way and the heim joints thread out making it all longer. I get them from Rod End Supply in Kansas.
    Here: http://www.rodendsupply.com/index.php
    http://www.rodendsupply.com/radius-rod-length-guide.php

    If memory serves me those are 5/16" diameter shaft rod ends with 5/16" bore holes. If you need me to do so, I can measure them.

    Rod End Supply also sells Weld-In Bungs. You can use those when you making your adjustable length upper struts from the bike to the car.

    You can also source this stuff from any race, machine, or off road supply like Summit Racing, McMaster Carr, etc.

    There's plenty of experts here on the subject that can chime in. I don't think the problem is so much in riding a bike with leading links, in fact many bikes have been manufactured with link forks. I think the problem is in the fact when you build leading links for a sidecar rig you do so with the intention (and geometry) of significantly reducing the trail, which makes the solo bike a death trap.

    Leading links can indeed be built to run solo. It has been done for years. The earlier BMWs had them.. The Greeves motorcross bikes had them etc etc. The key is to build in an adjustable trail to be able to switch back and forth safely.
    Personal;ly I thinkleading links make aton of sense in either case. Face it tele forks are basiclly a wheel on the end of two shock absorbers....kinda weird when ya think about it.

    Thanks for the info! I had never really thought of it like that before. I have seen bikes with the adjustable trail. I will be doing that. So I would imagine that for solo riding i should make the trail about what it is with conventional forks? I'm sure it is very subjective but what is an estimate for the proper amout of trail for the side car setting on the LL swing arm? Thanks for your help!
