Hy Draz,
Thank you. I know a few of the Al Frames with downhill geo… but i search for Carbon and was surprised don‘t find any.
My point is with that much of front travel you may need a rear suspension, if you want to go carbon.
AL should give more compliance, better suited for long travel hardtails.
You are basically looking for an XC carbon frame with enduro type head angle which should be quite rare.
I have a 65degree AL hardtail and carbon full sus.
As an engineer and a rider, I just don't recommend stiff rear and trail size fork.
Of course thats just an opinion but the fact that AL version offered in that geo is way more common, kinda backs my opinion.
