Paulevans…the HT should come with a LL tune Debonair RT3. It should also come with 4 spacers in the can iirc.
I am 95kg+ and didn’t get on with the debonair rt3, to me it just didn’t feel supportive and struggled with pressures to get anywhere near what I wanted.
I have now replaced it with a Fox DPS EVOL shock in a slightly firmer tune, the difference is noticeable. Funnily enough the newer HT come with Fox DPS EVOL as standard read into that what you want.
By the way love my HT, superb bike. Had it at 150mm front and now at 140mm in 29er. Can imagine the HT LT is a more focused machine erring towards the more gravity oriented end of things.
