Biking Type:
Mountain
More
Biking Type
Mountain Mountain bikes are built for tackling rough terrain with frames made of durable materials like aluminum or carbon fiber, ensuring stability and maneuverability. They feature suspension to absorb impacts from rocks, roots, and drops, providing a smoother ride.
-
Used For:
Downhill
More
Used For
Downhill For bike park days and shuttle laps, there’s nothing like a downhill (DH) bike. Designed to tackle the roughest trails at high speeds, these bikes have long suspension travel (typically 170mm+), huge brakes, and unreal descending capabilities. DH bikes are not as suitable for tight trails or climbing.

Suspension:
Full Suspension

Suspension
Full Suspension Engineered to tackle the most challenging terrain with enhanced comfort and control. Unlike hardtail bikes, full suspension bikes feature both front and rear suspension systems that allow the wheels to move independently from the frame.

Front Tire
Maxxis Assegai 2.5" | 3C MaxxGrip, DH, TR Greg Minnaar’s signature tire – the Maxxis Assegai – provides tenacious, predictable grip across the entire profile no matter the lean angle. The Assegai can be used front and rear for a surefooted feel or as a front paired with a faster rolling rear tire.- 3C MaxxGrip: The stickiest, slowest rebounding rubber Maxxis offers.
- DH: Downhill casing tires are designed for extreme use in all gravity applications from downhill racing to bike park riding to free riding to long travel e-bikes. Made with two layers of durable 60 TPI casing material along with a large butyl rubber insert that extends from each bead into the sidewall. The butyl insert helps prevent pinch flats, protects the rim from impacts, and provides additional sidewall stability.
- Tubeless Ready (TR): Tubeless tires allow riders to run lower air pressures for improved traction, lower rolling resistance, and less chance of flatting.
