Trek Roscoe
Newer mountain bikers and anyone who wants a hardtail that forgives line choice.
Plus-tire hardtail character: planted, playful, and slower to sprint than Top Fuel. Geometry got slacker through the late 2010s.

Plus-tire hardtail character: planted, playful, and slower to sprint than Top Fuel. Geometry got slacker through the late 2010s.
Riders who want a drop-bar bike for mixed-surface events, not a touring mule.
Gravel-race geometry with a distinctive front end. Quick to turn and happier on fast dirt than on loaded bikepacking tracks.
Hardtail trail riders who do not want a full-suspension Hightower.
The trail hardtail Santa Cruz: slacker than Highball, happier with bigger tires and a dropper.
Trail riders who want one Specialized and are willing to size by reach. Enduro-curious riders should look at Stumpjumper EVO or Enduro; XC racers at Epic.
The first S-sizing Stumpjumper: six frame lengths from S1 to S6 with short seat tubes, so reach and wheelbase pick your size instead of your inseam. Travel dropped to 130 mm rear behind a 140 mm fork, leaving the longer stuff to the EVO.
