Trek’s entry-level aluminum hardtail mountain bike.
Fantastic frame geometry
Excellent shifting
Good tires
Looks great
Generous tire clearance
Easy-to-live-with semi-internal routing
Sort of a rear thru-axle.
Mega-heavy fork with minimal adjustability
Tubeless costs extra
Limited upgrade potential.

Riders can expect updated geometry, a new frame, increased tire clearance and a rear axle system that "enhances stability," Trek said.

Can the Marlin compete with the bigger players?
Lots of frame sizes
Excellent tyre choice
Dropper seatpost
Upgrade potential
Roomier seated position would be preferred
Quick-release rather than thru-axle
Rattly internal cable routing
