The Deore components ensure smooth and efficient shifting across a wide range of gears, empowering riders to conquer steep ascents and rapid descents with confidence. The drivetrain's performance is a crucial aspect of the Growler 40, allowing riders to focus on the trail ahead without interruptions.


Front suspension is a pivotal component for absorbing shocks and maintaining control on rugged trails, and the Growler 40 features a Suntour Raidon 34 LOR Air Boost 140mm fork. With 140mm of travel, this fork is optimized to handle a variety of obstacles and uneven surfaces.

The WTB ST i30 TCS 2.0 Tubeless wheelset adds a layer of versatility to the Growler 40. These wheels are designed to be tubeless-ready, offering advantages such as reduced risk of flats, lower rolling resistance, and enhanced traction. The 30mm internal rim width provides a stable platform for wider tires, contributing to improved grip and control on challenging terrain. The tubeless capability further enhances the bike's performance, allowing riders to explore rough trails with confidence.

Braking performance is a critical consideration, and the Growler 40 is equipped with Shimano MT4100 2 Piston brakes. Shimano's reliable braking technology ensures precise modulation and powerful stopping force. The 2-piston design strikes a balance between control and power, allowing riders to navigate descents and technical sections with confidence. The inclusion of these brakes emphasizes the Growler 40's focus on safety and control.

Tires play a pivotal role in a mountain bike's performance, and the Growler 40 features Maxxis Minion DHF 2.6 EXO front and Maxxis Minion DHR II 2.6 EXO rear tires. The Maxxis Minion series is renowned for its aggressive tread pattern and high traction, providing confidence-inspiring grip on a variety of trail surfaces. The 2.6-inch width strikes a balance between stability and maneuverability, allowing riders to tackle technical climbs and descents with ease.

148 Steel Rear Axle

Completing the package is the Rocky Mountain 148 Steel, a rear axle designed for strength and durability. The 148mm Boost spacing enhances wheel stiffness and provides additional clearance for wider tires. This rear axle contributes to the overall stability and control of the Growler 40, ensuring that riders can confidently navigate technical terrain.
