At THOR Carbon Bike Tuning, we believe that lightweight carbon parts makes you drive better and faster. Therefore, we developped an attractive Carbon Boost Fork (15x110 mm), a meticulously engineered rigid carbon fork that’s been popular for many, many years. Whether you're challenging KOM on MTB single tracks, riding on beaches, ripping through gravel, or transforming your hardtail MTB frame into a versatile all-rounder.

100% Toray carbon construction—no compromises
Crafted from 100% high-grade Toray carbon, this lightweight yet incredibly strong fork showcases our commitment to quality. Delivered in a matte or glossy finish.

Optimized for performance and clearance
Designed with a 45 mm offset and compatible with 160 mm rotors (larger is possible via adapter), this fork ensures precise handling and responsive steering. The fork can handle 3‑inch tyres—suitable for every discipline.

Tapered steerer and sleek Boost axle design
The 1.5″ → 1⅛″ tapered carbon steerer adds stiffness and precise front-end control. The included smooth thru-axle keeps the design minimalist and functional. The thru-axle  is threaded directly in the fork, so the old fashioned screw cap really belongs to the past now. The high quality finish decals gives the total setup a fawless looks and feel.

Lightweight and built to last
Coming in at approximately 600 g (±3%), this fork is featherlight without compromising durability. It’s fully ISO 4210-tested and covered by a 36-month warranty on manufacturing defects. Optional accessories—like a expander set for secure frame mounting or our featherlight flat top cap—let you personalize your build even further.

Designed for real riders and real bikes
Whether you're beach racing, hitting light singletrack, or outfitting a gravel hardtail, this fork brings high-level carbon performance to your front end. Hand-finished with understated black‑on‑black THOR branding and available in both satin and gloss finishes, it blends style with rugged capability.

Mount it straight into your frame, pop in the axle, and you’re ready to ride—Beach, Gravel, All Road, or MTB XC trails. LET'S GO!
