Santa Cruz Bullit 4 CC XT Di2 Reserve E-Mountain Bike 2027

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.

If you’re looking for maximum performance while flying down heavier trails, an enduro bike is for you. These bikes combine ample suspension travel (typically 150mm+) with descent-focused frame geometry and components that allow for reasonably efficient pedaling.

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.

Carbon is a composite frame material. Unlike metals, carbon is composed of fibrous strands woven into a grid and bonded with epoxy. Carbon is favored by many for its lightness and stiffness but its complexity in fabrication makes it the most expensive option.

Podium is designed to be ridden like a downhill fork. No barriers. No hesitation. Complete confidence that your front wheel will hold the line, no matter how fast or how big you push it. All this while keeping your bike in a familiar range of travel and geometry in a single crown package.

Nothing sticks to the ground quite like a coil shock. The DHX2 takes that sensation and buttresses it with sophisticated progressive damping, a massive overall tuning range, and super low-friction internals in order to capitalize on the full race-spec magic carpet experience.

The next generation Bosch Performance Line CX motor is quieter, lighter, and smaller than ever. More compact but no less powerful, it comes with a maximum torque of 85Nm. Choose between 4 standard modes and customize your ride in the Bosch Flow App.

Thanks to their range, long service life, intelligent battery management system and easy handling, Bosch Power Tube lithium-ion batteries are among the most modern on the market. All those decades of Bosch experience has paid off!

The Shimano XT Di2 shifter feels instantly natural out of the box, but can also be molded to fit any hand, thanks to its familiar fit and evolved adjustability design. Multiple shift modes, like hold-down multi-shift and 2-step multi-shift, offer versatility and precision, while the tactile click prevents mis-shifts and a tunable third button allows for additional system tuning or third-party connection.

Wireless Di2 shifting designed for E-MTB and HYPERGLIDE+. The ultra-durable RD-M8260 long-cage, 12-speed rear derailleur taps into proven wireless Di2 shifting technology and the strengths of other XT offerings, while pulling power from the bike's main battery, delivering a stable power supply, and eliminating the need for a back-up battery.

With its Beam Spider construction, the Deore XT M8100 cassette shaves weight while increasing Shimano's MTB gearing range another gear. Using a Micro Spline freehub body and HYPERGLIDE+ tooth profile, these 10-45 and 10-51T cassettes deliver advanced shifting performance.

 

The M8100 chain provides enhanced chain retention thanks to an extended portion of the inner plate. The chain features quick-link assembly and SIL-TEC treatment for extended offroad durability.

SRAM Maven Silver features monstrous 18 and 19.5mm pistons driving 50% more power than Code. But best-in-class power means nothing unless you’re able to harness it. The Maven Silver lever body houses Swinglink, which translates rider input for progressive power throughout the lever pull, maintaining SRAM’s signature ride feel. And because of a stiff 4-bolt caliper that sheds an incredible amount of heat, that feel remains consistent, so the last corner feels like the first corner. Maven Silver features a bold black anodized finish with stainless hardware. And for unrivaled ease of customization, features tool-free Reach and Contact Point Adjust.

Known for its no-nonsense smooth cable actuation, short overall length, and easy serviceability, the OneUp Dropper is a solid choice for dependable and customizable performance.

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.
• DoubleDown (DD): Two layers of lightweight 120 TPI casing combined with a butyl sidewall insert creates a highly durable tire with more trail feedback than a Downhill casing tire.
• Tubeless Ready (TR): Tubeless tires allow riders to run lower air pressures for improved traction, lower rolling resistance, and less chance of flatting.

With side knobs borrowed from the legendary Minion DHF, but widened to provide more support, the DHR II corners like no other. The center tread features ramped leading edges to improve acceleration and sipes to create a smooth transition when leaning the bike. Paddle-like knobs on the center tread dig in under hard braking and help keep the bike under control.

• 3C MaxxTerra: A triple compound ideal for trail riding in all conditions - offers more traction than 3C MaxxSpeed, yet provides better treadwear and less rolling resistance than 3C MaxxGrip.
• DoubleDown (DD): Two layers of lightweight 120 TPI casing combined with a butyl sidewall insert creates a highly durable tire with more trail feedback than a Downhill casing tire.
• Tubeless Ready (TR): Tubeless tires allow riders to run lower air pressures for improved traction, lower rolling resistance, and less chance of flatting.
