the company that makes the head tube sections for your jig is called Chop source

Thanks Hard tail. They have some nice stuff. A buddy of mine and myself want to build a couple of gravity trikes. There are lots of hills around here and its not but an hour to get to the big hills that guys are riding all the time. We would like some experienced advice on one thing. What are you setting the head tube angle? We have read all kinds of numbers on the internet and there doesn't seem to be a "best" number that all the gravity guys agree on. We just don't want to have to cut up a finish trike to adjust the angle and guess at what we need. Thanks again for the info. This will get us started on the road to having a little fun.

we have seen others use anything from 28 to 37 we use 32 for all our builds

Thanks Hardtail. We were looking at something in the 25 to 30 degree setup. We have seen as low as 22 and as high as 38 posted on the internet. Just to much range to pick a number from. If that works for you it should work for us too.

Thanks again.

as an update itis now three years since that jig was built we still use it today every day we have built literally hundreds of drift trikes on it. Also we now have both a lathe and a mill as well as a cnc tube bending machine. and yes i am in the process of my first every motorcycle build. It has been a lot of hard work but steadily we are gaining ground. now if i only had a bigger shop LOL
