Sidecar Wheel Lead

Hi Guy's

Well My brother has decided to fit a trials sidecar to the Ariel HS frame we have. To replicate the outfit that I used to passenger. My task in the operation is to build the chair. Have looked up all the sidecar dimensions In the ACU hand book and have used them as a guide to the build using the minimum measurements ,But trying to keep it looking like a Kendall as much as possible. Well it is to be named "Spirit Of 65". Well to stop rambling, What I need to know is the amount of sidecar wheel lead from the bikes rear spindle, that you boy's are using now- a- days , as it is a long time since I last built a chair, and my memory does not go back that far. Hope you can help? I think I need a chair to sit down on now.

Regard's Charlie.

I'm pretty sure the lead used to be about 9" but modern outfits are 10.5".

Trouble is if you put 10.5" lead on a sidecar without a sidecar brake you will struggle to turn left on a downhill or a chair high camber.

But in contrast the less lead you put on the worse it is turning right.

Hi Guy's.

Hi Robin,

Thanks,You should be the Boy to know. I thought I could remember, that we used to use about 9 inch lead but did not want to carry on with the build until i had confirmation . Its a long time since the sixties but i must have had it in the back of my mind , I can also remember competing with your dad though. Thanks again for the information will post a picture when we get the plot finished.

Regards Charlie.
