Chain stay length help please?
I am using BikeCAD (free version) to design the basics of a single speed trail bike that I'd like to build. I am only laying out the primary dimensions in a profile view so that I'd have a somewhat realistic starting point for discussion with a frame builder once I choose one.
How long must a steel chain stay be to accomodate a 26 inch (559) x 55mm tire while running a 42T chainring on a 68mm BB?
It's easy enough for me to position the virtual rear wheel anywhere I like, but I know that there would need to be some length for the bends to create the needed clearance as the stays come off of the bottom bracket.
Thanks for any advice or comments.
