ridden all three (Lynskey Ti) and owned a steel and a carbon.
Geometry feels the same across the three ride characteristics are what you’d expect really;
steel – pretty solid – it’s not an expensive frame, it has some spring but not much give. chuck it around and not worry about breaking it.
Carbon – solid but smooths out trail chatter pretty well. tendency to amplify the slightest squeak from a component, can sound like a tupperware box full of marbles on a fast descent on a loose surface as small stones ping off the frame. really light.
Ti – very springy, possibly too much ‘give’ in it for my tastes (although I only rode it around the local woods, not on an all day epic).
of the three, for me, the carbon is the best compromise between cost, performance and weight.
They seem to ride ‘best’ with a 140mm fork on, ime.
