2026 Santa Cruz Blur 90 TR – Precision-Built for the Fast Lane of Trail Riding
The 2026 Santa Cruz Blur 90 TR is purpose-built for riders who demand efficiency without compromising capability. Engineered around a trail-optimized platform and outfitted with a no-nonsense parts kit, this bike blends featherweight agility with all-mountain confidence—perfect for marathon racers, speed-focused XC riders, and technical singletrack enthusiasts alike.
Suspension That Knows No Limits
At its core, the Blur 90 TR is equipped with the FOX 34 SL Float Performance fork, offering 120mm of supple, responsive travel to smooth out rough terrain without sacrificing control. Complementing it is a FOX Float SL Performance rear shock (190x45), finely tuned to balance traction and pedaling efficiency. Together, this suspension combo ensures the bike feels light on the climbs and planted on the descents.
Next-Gen Drivetrain: SRAM T-Type
The Blur 90 TR comes fully loaded with SRAM's revolutionary Eagle T-Type Transmission, delivering precise shifting and bombproof chain retention under load. The setup includes:
-
SRAM 90 Eagle DUB T-Type crankset with a 34T chainring
-
SRAM XS 1275 Eagle T-Type 10-52T cassette offering a wide gear range for any incline
-
SRAM GX Eagle T-Type Flattop 12-speed chain
-
SRAM 90 Eagle T-Type derailleur and 12-speed shifter
The SRAM DUB 73mm MTB Wide BB ensures a stiff, efficient power transfer platform that enhances every pedal stroke.
Confident Braking, Unflinching Control
No matter how technical the descent, the SRAM DB8 brakes paired with 180mm SRAM HS2 rotors front and rear deliver powerful and consistent stopping performance. These 4-piston stoppers are built to instill confidence whether you’re feathering through switchbacks or diving into high-speed chutes.
Trail-Ready Cockpit and Controls
Control and comfort are key, and the Blur 90 TR delivers on both fronts. The SRAM Atmos flat bar (31.8x760mm) and 60mm Atmos stem offer precise steering response, while the SDG Bel-Air V3 Lux-Alloy saddle and OneUp Dropper Post (31.6mm) provide ergonomic support and on-the-fly saddle height adjustability. The Cane Creek 50 IS Integrated headset ensures durability and a tight steering interface.
Lightweight Yet Tough Wheelset
Built for speed and reliability, the Blur 90 TR rolls on RaceFace AR Offset 27 29" rims, laced to dependable DT Swiss 370 hubs (15x110 front, 12x148 rear). With 28h spoke counts and 6-bolt compatibility, these wheels are trail-tough yet race-light. Wrapping it all up are Maxxis Rekon 29"x2.4" WT tires front and rear, featuring 3C MaxxTerra compound and EXO casing for superb grip and durability across mixed conditions.
The Verdict:
The 2026 Santa Cruz Blur 90 TR is more than just a trail-ready XC bike—it's a race-proven, performance-focused machine for riders who want a lightweight rocket with real trail manners. With high-end components, cutting-edge SRAM Transmission, and Santa Cruz’s renowned frame design and lifetime warranty, the Blur 90 TR is ready for any ride, any distance, any day.
