The Stiffi 3SX Tri-Spoke Wheel takes inspiration from Japanese hidden blades, creating a silent but deadly weapon-like wheel for riders who want speed, style and a bold cockpit-to-wheel setup.
Built with a Toray 8 carbon rim, 50mm rim depth and three NACA aerofoil spokes, the 3SX combines aerodynamic performance, stiffness and a striking visual profile. The 23mm internal width is recommended for 700×23-32c tires, making it suitable for fixed gear, track and road-focused builds.
The fixed gear version features a dedicated threaded hub with lockring threading, while the road version is compatible with Shimano, Sram and Campagnolo systems. Stiffi sealed NTN Japanese bearings provide smooth rotation and reliable support.
The basalt brake surface is designed for rim brake systems. Standard specification comes with UD carbon weave and Stiffi WHT Fade Logo™ decals. Custom weave options and decal colors are available by request before ordering.
⚠️ Price is for one wheel only. Please select front or rear wheel based on your setup.
