Santa Cruz Bronson CC Frameset 2025 - MX Wheel, 150mm VPP Trail Bike

The Santa Cruz Bronson Carbon Frameset is the evolution of Santa Cruz's renowned all-mountain machine. This latest generation (V4/V5) is exclusively designed around a Mixed Wheel (MX or Mullet) setup, featuring a 29" wheel up front for speed and stability, and a smaller 27.5" wheel at the rear for agility, clearance, and a truly playful feel.

The frame offers 150mm of travel delivered by the latest Lower-Link VPP™ (Virtual Pivot Point) suspension platform. This kinematic has been refined for the mixed-wheel design, offering a plush, highly active ride with excellent mid-stroke support and less anti-squat than previous generations, resulting in improved small-bump traction both climbing and descending. The frameset typically includes a high-end shock, such as the RockShox Super Deluxe Ultimate.

RockShox ZEB Ultimate Fork 2025 - 38mm Charger 3.1 RC2, DebonAir+ Air Spring

The RockShox ZEB Ultimate is the pinnacle of single-crown performance, explicitly engineered to handle the most aggressive Enduro race stages, Freeride trails, and modern, long-travel mountain bikes. Built around a stout 38mm chassis, the ZEB Ultimate delivers a blend of stiffness and steering precision that instils confidence on the gnarliest descents.

  • Charger 3.1 RC2 Damper: The flagship damper features a high-performance Internal Floating Piston (IFP) design and offers truly independent High-Speed Compression (HSC), Low-Speed Compression (LSC), and Low-Speed Rebound (LSR) adjustments. This eliminates "cross-talk" between circuits, allowing riders to dial in the perfect, precise damping feel without compromise. The 3.1 update provides an even wider, more usable adjustment range for world-class tuning.

  • DebonAir+ Air Spring with ButterCups: The highly tuneable DebonAir+ spring is designed for a plush, 'butter-like' feel off the top, excellent mid-stroke support to hold the fork high in its travel, and a smooth ramp-up. ButterCups are small rubber pucks housed at the base of the damper and air spring that block $\text{20\%}$ of high-frequency 'trail chatter' (vibrations), significantly reducing arm and hand fatigue.

  • 38mm Stanchion Chassis: The burly 38mm upper tubes and robust magnesium lowers maximise bushing overlap, which contributes to its exceptional torsional stiffness. This ensures precise tracking and control, especially when charging through technical sections at high speed.

  • Pressure Relief Valves: Located on the back of the lower legs, these simple valves allow riders to relieve built-up air pressure in the fork's lower legs at the touch of a button, ensuring consistent, optimal spring performance, particularly during long descents or changes in altitude.

The ZEB Ultimate, with its premium machined crown and ultra-low friction SKF seals, is the essential weapon for riders who demand top-level performance, ultimate tunability, and race-proven durability.

Grips

Select:

Single lock-ring design with the staying power of dual lock-ring.  A taper-lock core uses an internal sleeve that narrows towards the last 38mm (1.5”) of the grip, effectively clamping onto the end of the bar to eliminate twisting.

Flared closed end for comfort, feel and security.  8mm (0.3”) of rubber with a subtle mushroom profile on the tip resists scuffing, provides comfort and adds an intuitive feel for the bar end.  (We also found it adds a healthy dose of forgiveness when clipping trees on tight trails!)

Long grip length and waffle knurl for maximum control.  A generous 125mm (4.9”) grip length (excluding lock-ring) allows plenty of room to reposition hands on differing terrain and long rides.  The moto-knurl pattern gives just the right balance of feel and grip in all conditions.

Saddle

Select:

Performance gravel saddle with Lux-Alloy rails. Features a full cut-out, ATMOS sealed construction, and 225g weight.

The SDG Bel-Air V3 Overland Lux-Alloy is the streamlined, gravel-and-XC-focused sibling of the legendary Bel-Air mountain bike saddle. While the standard V3 is known for its pronounced "rear rise" and chunky protective bumpers, the Overland edition is "levelled off" with a lower profile and a full cut-out.

Features:

Nylon Glass Base: Features an integrated "bridge" to increase power transfer and prevent the saddle from sagging over time.

Injection EVA Foam: Uses a lightweight, high-density foam that provides firm support without feeling "mushy."

Wider Nose Platform: Provides extra surface area and support when you are "on the rivet" during steep, technical off-road inclines.

One-Piece Microfibre Cover: A seamless, friction-free surface that stays cool and is incredibly easy to clean after a muddy ride.

Tyres

Select:

World Cup Champion Greg Minnaar's signature tyre.

  • 3C MaxxGrip rubber compound available
  • Dual-ply downhill casing
  • Tubeless compatible
  • Wide Trail casing optimized for 30-35mm rims

The Maxxis Assegai tyre is named after the iron-tipped spear used by the Zulu people of South Africa. Greg Minnaar, a native of South Africa, thought it was a fitting name for a tyre ready to do battle on the mountain. The tall knobs punch through dust and loam to find traction, but also offer support and confidence on wet roots and rocks. While other tyres excel only in certain conditions, the new Maxxis Assegai is built to go fast everywhere.
