Trek 3700 Mountain Bike Pros & Cons


Versatile Drivetrain: The Shimano components (Tourney shifters, Altus derailleurs, and M131 crankset) offer various gears suitable for diverse terrains.

Quality Components: Bontrager parts, like the Evoke 1 saddle, SSR seatpost and handlebar, and the Approved stem, are known for their quality and durability.

Disc Brakes: Tektro Novela, mechanical disc brakes, provide reliable stopping power, which is crucial for safety, especially on downhill trails.

Sturdy Frame: The Alpha Silver Aluminum frame is lightweight and robust, ensuring durability for off-road usage.

Versatile Tires: The Bontrager LT3, 26×2.0″ tires are well-suited for varied terrain, providing good traction and rolling efficiency.


Entry-Level Components: Components like the Shimano Altus derailleurs and Tourney shifters, while reliable, are at the entry-level end of Shimano’s range and might not perform as well as their higher-end counterparts.

Coil Spring Fork: The SR Suntour XCM coil spring fork isn’t as adjustable or lightweight as air spring forks on more expensive bikes.

Mechanical Disc Brakes: While disc brakes are a plus, these are mechanical (or cable-actuated) rather than hydraulic, which offer better modulation and performance.

Wheel Size: As mountain bike trends are moving towards 27.5″ and 29″ wheels for better rollover capability, the 26″ wheels on the Trek 3700 might feel a bit outdated.

Platform Pedals: While durable and easy to maintain, some riders might prefer clipless pedals for better power transfer and control during technical riding.
