Learn More About the 2026 Santa Cruz Blur 4 C 90 TR
The 2026 Santa Cruz Blur C 90 TR is designed for riders who want a bike that climbs efficiently and handles technical trails with ease. It’s built around a trail-optimized frame that balances a lightweight feel with confidence-inspiring stability. Whether your rides lean toward marathon races, speed-focused cross-country, or technical singletrack, this bike stacks up.
The suspension-wise, the Blur C 90 TR features a FOX 34 SL Float Performance fork with 120mm of travel. This smooths out rough sections while keeping steering sharp. A FOX Float SL Performance rear shock (190x45) works alongside to deliver a blend of traction and pedaling efficiency. It doesn't weigh you down when climbing but stays firmly planted through descents.
The drivetrain is powered by SRAM’s Eagle T-Type Transmission, which is known for clean, reliable shifting and strong chain retention when the trail gets tough. You get a SRAM 90 Eagle DUB T-Type crankset with a 34-tooth chainring, a wide-range 10-52T SRAM XS 1275 Eagle cassette, a SRAM GX Eagle T-Type 12-speed chain, plus matching SRAM 90 Eagle T-Type derailleur and shifter components. A SRAM DUB 73mm MTB Wide bottom bracket completes the setup, ensuring your pedaling effort translates directly into forward motion.
You'll also find a set of SRAM DB8 brakes paired with 180mm HS2 rotors front and rear. These 4-piston calipers deliver consistent, powerful braking for tight switchbacks and high-speed descents. This gives you solid control no matter how steep or rough the trail.
On the cockpit front, you’ll find a SRAM Atmos flat bar with a 31.8mm diameter and 760mm width, connected to a 60mm Atmos stem for sharp, responsive handling. Comfort stays in check with an SDG Bel-Air V3 Lux-Alloy saddle mounted on a OneUp Dropper Post (31.6mm). This lets you adjust saddle height mid-ride. The Cane Creek 50 IS Integrated headset adds durability and smooth steering feel.
Rolling on RaceFace AR Offset 27 rims sized for 29" wheels, this bike uses DT Swiss 370 hubs (15x110 front, 12x148 rear) laced with 28 spokes each. The wheels are sturdy enough for aggressive trails but light enough to keep you moving fast. Maxxis Rekon 29x2.4 WT tires with 3C MaxxTerra rubber and EXO casing offer great grip and protection in mixed conditions.
If you want a lightweight bike that can hold its own on demanding trails and long rides, the Blur 90 TR fits the bill. Santa Cruz’s solid frame design backed by a lifetime warranty and the top-tier parts package make it a dependable partner for many seasons of riding.
