This is a bit of a peeve of mine: I know we bicyclists use the word "rake" to refer to offset, but I wish we wouldn't. Rake, if you look it up in a dictionary, really refers only to the inclination from vertical or horizontal.
...
Relative weight loading is also pretty important. I have a couple bikes (relaxed angles, lots of offset) that shimmy badly unless I lean forward.
One just has to accept the long used terminology. Talk to a motorcycle designer and he will also pull his hair out regarding all of the bicycle nomenclature.
