I'm relatively new to MTB. I bought an REI Co-op DRT 1.1 hardtail about 2 years ago. It's decent but I ride with guys who have full-suspension Santa Cruz or Cannondale bikes and they can manage to get up more tricky terrain. I find myself walking my bike more than I'd like.
I've seen some 6 or 7 year old seemingly better bikes on FB marketplace for $600-800 like a Ghost Kato FS 7
Is that decent upgrade from a hardtail while on a budget? What's the best options for upgrades under $1000?
It's mostly rocky hilly terrain and some gravel narrow tracks in central Texas.
Does your bike have a dropper post? If not, I'd consider getting that one. It's not an expensive upgrade ($60-$200 upgrade) but does wonders on long and sustained up/downhill trails.
