Down tube angle custome Help?

[Klondike1020]

Is there any sort of formula or anything to go by when deciding on a down tube angle
maybe somthing that takes into account the center of balance ride height turn radius weight... ect

Cause i am considering modding an old quad into a trike the frame looks like an easy conversion i am just worried it has a high center of graity and suspension travel. ect

any advice from teh more exsperianced would be greatly appreciated!!!

"Rake pertains to the angle of the steering head in relation to the ground.

The stretch is the length of additional tubing added to the back bone or down tubes of a motorcycle frame compared to a stock Frame
Usually a combination of rake and stretch are used to determine "TRAIL"


Trail is the most important part of the equation.

There is a great Rake-Stretch-Trail Calculator on Perse Performance's Website located at www.perseperformance.com,
Imput your dimensions and the calculator will tell you if it will be a safe ride or not"
