Santa Cruz Blur 4 CC TR XT Di2 S *Contender Custom*

The Santa Cruz Blur 4 CC TR XT Di2 Contender Custom Build is a high-performance full-suspension cross-country mountain bike engineered for speed, precision, and versatility on demanding trails. Crafted for riders who crave adventure and aggressive trail performance, this custom build combines cutting-edge components with the legendary Blur geometry to deliver a race-ready experience that inspires confidence from climb to descent.

At its core, the Blur 4 CC TR features an ultralight, stiff, and durable Matte Carbon CC frame, optimized for trail efficiency and control. The custom build pairs this frame with the Shimano Deore XT Di2 wireless 12-speed drivetrain, delivering crisp electronic shifting for precise, effortless gear changes under any conditions. Paired with the Shimano Deore XT brakes and crankset, this setup ensures seamless integration and reliable stopping power for technical terrain.

Suspension performance is dialed in with a Fox 34 Float SC Factory fork and a Fox Transfer SL dropper post, complemented by rear travel tuned for trail versatility. The system balances plush bump absorption with firm pedaling efficiency, while the Fox Twin Stick remote lever allows intuitive adjustment of both lockout and dropper functionality. This combination provides confidence and control, whether you are powering up steep climbs or descending at full speed.

The Blur 4 CC TR’s trail-focused geometry features a slightly steeper head tube angle and shorter reach for aggressive climbing, while a slightly slacker seat tube angle and longer chainstays maintain stability and control on descents. This is enhanced by the Pro Stock Reynolds TR 309 CL Disc wheels, paired with Maxxis Rekon Race tires, providing traction, speed, and responsiveness across mixed terrain. The Enve alloy stem and Specialized S-Works Carbon handlebar complete the cockpit, delivering precision steering and comfort for long rides.

Every detail, from the Cane Creek 40 headset to the Fizik Antares R7 saddle, has been selected for performance, durability, and rider comfort, making the Blur 4 CC TR XT Di2 a complete trail weapon built for XC racing and high-speed adventures.
