Marlin 7 Gen 3

The Trek Marlin 7 Gen 3 is a common first mountain bike because it hits the right balance of price, reliability, and capability for a full NICA season.

It’s a hardtail with a longer wheelbase and slacker front end, which makes it more stable on descents and less twitchy as speed increases. It uses Shimano MT200 hydraulic disc brakes, which are consistent and easy to modulate, and a SRAM NX Eagle 1x12 drivetrain, which offers a wide gear range and more durability than lower-tier options.

This is not a high-performance race bike. The fork and overall build are entry-level, and stronger or more experienced riders will outgrow it as speeds increase and terrain gets rougher. But for newer riders, it does the job without requiring a large upfront investment.
