I have a featherlight hardtail Giant Carbon XTC 29er for sale. It's a size large, but with a very interesting custom carbon seatpost added by the previous owner who knew how to lay carbon.
Here are the various parts I have on it:
-Giant S-XC2 wheelset - 29"
-2021 Rock Shox Recon RL w/ Magnesium stanchions, air adjustable.
-Ritchie seatpost bracket
-Specialized Ti race saddle
-2020 Truvativ X9 front crank
-2020 Deore XT rear derailleur
-2020 Deore XT front and rear hydraulic brakes
-2019 Hardrcock'r FlakJacket tires
-2018 Magnesium Black Ops TorqLite Ultra-lightweight pedals
It's a pretty darn good hardtail for the price - not much better you'll find in carbon. I'd say it fits someone between 6'0-6'5", thought if you're willing to cut (or have a bike shop cut) the carbon seatpost down to your exact height, it might fit shorter.
