after 18 months on the full sus, im about to start on the hardtail agin..started last weekend and i was ‘somewhat tired’ after the hardtail ride..quite alot tired tbh….why was that….. anyway im out tomorow for another session…hope it gets easier..lol 😉

Tired because you feel beat up or because you worked harder?
Could be because bike set-up is slightly different – you may be bringing different muscles in to the equation. I expect to feel tired tomorrow as first mtb ride for a while after months on the road bike – different riding position!!!

Bit more use of the legs to soak up bumps?

more use of the legs ..hmmm..i already overwork my little legs (5ft small here)….
when im out with other people i seem to cycle 4 revs to their two if ya know what i mean (hard work for us little un’s …lol 😉
