2024 Santa Cruz Blur 4 C S

The 2024 Santa Cruz Blur 4.1 C S-kit is a fast and nimble cross-country bike that handles everything from flat-out racing on gravel, to sketchy descents and small jumps with ease.

The frame is lightweight, strong C-level carbon from Santa Cruz. While C is the "lower" end carbon frame that SC offers, it's nowhere near low end. It's a durable, stiff, vibration-absorbing frame material that's rideable and fully enjoyable in all kinds of conditions. This frame keeps the bike agile and responsive, giving you confidence on technical trails without feeling like you're sacrificing durability.

Drivetrain

Shifting is straightforward and precise thanks to the SRAM GX Eagle 1x12 drivetrain. It has enough range to power you up steep hills and keep you pedaling smoothly on flats. If you’ve been looking at high-end bikes you’ll recognize the Eagle name as belonging to SRAM’s high-performance range. It’s famous for fast, precise, reliable shifting. It offers a wide gear range, making those steep climbs less daunting and the speedy descents smoother. The gearing shifts cleanly and reliably no matter how rough the trail gets, so you can focus more on the terrain instead of your drivetrain.

Brakes

You'll also find a set of SRAM Level TL hydraulic brakes. They're steady and easy to modulate, so you can dial in the right amount of braking during tight turns or fast descents without grabbing too much or too little.

Suspension

Up front, a RockShox Sid SL Select+ fork offers 100mm of travel to soak up bumps and keep the front wheel planted. The RockShox SidLuxe Select+ rear shock matches that travel with 190x40mm dimensions. Together, these keep the ride smooth and efficient. You can pedal when you want to and let the suspension do the work when the trail turns rough.

Suspension Design

The bike’s Single Pivot suspension design is refreshingly simple. It's designed to efficiently maintain traction and stability without the complexity or maintenance headaches some other systems bring. This keeps the ride balanced and predictable no matter the terrain.

Derailleur Hanger

Cutting down on downtime, the SRAM UDH (Universal Derailleur Hanger) means replacing the derailleur hanger is straightforward if you bend or break it.

Dropper Post

Comfort and control get a boost from the Fox Transfer SL Performance dropper post. Changing saddle height on the fly has never been easier, so you can quickly move from climbing position to attack stance when the trail demands it.

Wheels and Tires

Rolling on RaceFace AR Offset 27 29” wheels with DT Swiss 370 hubs, the bike blends toughness with low weight. These wheels are ready for the beatings cross-country riding dishes out. On those wheels sit Maxxis Aspen 29"x2.4"WT tires with EXO and TR protection, striking a good balance between grip, durability, and rolling efficiency. They keep confidence high no matter the surface.

Steering and Bottom Bracket

Steering stays smooth and precise thanks to the Cane Creek 40 IS integrated headset, while the SRAM DUB 68/73mm threaded bottom bracket helps put every pedal stroke to good use without losing energy.

If you want a mountain bike that can keep up when the trail gets demanding and shifts seamlessly between aggressive riding and smooth pedaling, the Blur 4.1 S-kit is ready.
