Suntour Voro Coil

Suntour Voro Coil

The Suntour Voro Coil shock brings a supple, grounded feel to the Bonnell 775 MX with a trunnion mount design and a 205x65mm spec, meaning 205mm eye-to-eye with 65mm of stroke for controlled, deliberate suspension travel built for aggressive riding.

The Voro Coil is a nuanced, dialed-in setup. Compression damping is controlled via a five-position blue knob on the top of the shock, allowing for fine-tuned low-speed compression adjustment depending on trail conditions and rider style. A red knob at the bottom offers low-speed rebound adjustment, helping you control how quickly the shock returns after absorbing an impact.

Coil shocks naturally offer a more linear and planted ride feel, ideal for riders who want maximum sensitivity off the top and consistent support through the stroke. We’ve matched spring rates to frame size for optimal performance out of the box:

Medium: 450 lb spring
Large: 500 lb spring
X-Large: 550 lb spring

Designed for durability, sensitivity, and confidence at speed, the Voro Coil is ready to handle serious terrain with minimal fuss.

Suntour Rux 38 RC+

Suntour Rux 38 RC+

Engineered for high-performance downhill front suspension is built to handle the toughest trails with ease. Featuring robust 38mm aluminum stanchions, it offers exceptional stiffness and stability without added weight. With 200mm of travel, it provides superior shock absorption on steep descents and technical terrain, while the RC+ damper offers precise tuning with adjustable rebound and compression settings, allowing riders to customize their setup for any trail conditions.

Equipped with a Boost 20x110mm thru-axle, the fork enhances wheel stiffness and supports wider hub spacing, delivering improved performance over rugged terrain. An integrated short fender adds extra protection, shielding the stanchions and seals from dirt and debris to ensure long-lasting reliability.

Magura MT5

Magura MT5

The Magura MT5 is a high-performance hydraulic disc brake system designed for powerful and reliable braking, making it ideal for demanding riding conditions such as enduro and downhill. It features four pistons, providing enhanced braking power and modulation, which ensures precise control and smooth deceleration. The MT5 is paired with MDR-P floating rotors, with a 220mm front rotor and a 203mm rear rotor, maximizing heat dissipation and maintaining consistent braking performance under high loads.

This braking system provides consistent, powerful stopping power with excellent heat management, making it a preferred choice for aggressive riders tackling challenging trails.
