Help me choose a MTB bike
I’m looking for advice on what direction to go for my first real mountain bike.
Current bike: Specialized Sirrus X 3.0. I like it overall, but on dirt paths/light trails it feels harsh and shaky over small bumps, roots, and uneven ground. I’m mainly looking for more comfort, stability, and confidence.
My riding style: late 30s, conservative/risk-averse, mostly riding mild local trails, fire roads, dirt paths, and trails with my 11-year-old son. This may become more of a shared hobby for us over time, so I’d like something we can grow into a bit. But realistically, I don’t see myself doing anything crazy like big jumps, drops, bike parks, or aggressive downhill. I care more about comfort, predictable handling, reliable brakes, and low-hassle ownership than max performance.
Bikes I’m considering:
REI Co-op DRT 1.3 — around $1,279 on sale. Seems comfortable and low-hassle with REI support, 120mm air fork, 2.6" tires, Deore 1x12, hydraulic brakes, thru-axles, and dropper.
Giant Fathom 29 1 — around the same price after build fee. Seems like stronger trail spec with 130mm air fork, dropper, 4-piston brakes, aggressive tires, and better name-brand resale. But REI has great return policy and support.
Specialized Rockhopper Comp 29 — around $1,000. More conservative/name-brand option with air fork, Deore 1x12, hydraulic brakes, lighter weight, but no dropper and older parts maybe?
Ozark Trail Ridge Pro M.2 — $598 if I can find one. Crazy value on paper with air fork, hydraulic brakes, thru-axles, Maxxis tires, and dropper
Used hardtail in the $400–500 range — also considering used bikes, preferably with a 1x drivetrain. Most options I’m seeing in this price range seem to have coil forks and no dropper. I’m not sure if I actually need an air fork or dropper for my use case, but I’d rather spend a few hundred more now if it gets me something more comfortable, reliable, and worth growing into.
Given my actual use case, would you buy a nicer new hardtail like the DRT 1.3 or Giant Fathom, go simpler with the Rockhopper, go best bang for buck for a Ozark if it comes back in stock? Or save money with a used $400–500 hardtail? Is the air fork/dropper/thru-axle stuff meaningful for a cautious mild-trail rider, or is all of this overkill?
Thanks!
