Is fork trail or chainstay length is a bigger determinant in the overall steering of the bike?
Consider an arbitrary frame that I think is steers too slowly. I'm going to rebuild it because I want a fun project, have some scrap metal, all the parts, and I want to build another similar bike that steers a bit quicker and is more racy.
All other things being equal, mainly the head tube angle, would building another frame with shorter chainstays be a better way to go about it than using a fork with less trail?
I'm interested in the rate of change in the steering of the bike while changing those two factors, and which one affects the steering more, and by how much if it can be measured - i.e. 1mm change in trail could be offset by 2mm change in chainstay length (that's probably wildly inaccurate - I'm hoping to hear from some frame builders).
