My mk1 c456 feels very “stiff” and “sharp” if i ride it immediately after riding my 160mm AMM (All Mountain Monster).
My mk1 c456 feels very “slack” and “dull” if i ride it immediately after riding my 80mm XC race bike.
Hmm, amazing how the bike must be changing between rides…..
(in reality, the c456 is light, stiff, and yet slack at the front. This means the front tracks well though bumpy stuff, very well actually, so when the unsuspended lightweight rear gets to those same bumps that the front hoovered up, i can see why people would describe it as “skittish” or “stiff”. It’s got nothing to do with the “compliance” or otherwise of the frame, and everything to do with being a generally lightweight long travel hardtail…… 😉
