Hope Pro 4 Fatsno

This hub is specifically engineered for fat bikes. With 150mm front spacing and a 15mm thru-axle, it is built to accommodate the wider forks and larger tire clearances typical of fat bike frames.

The larger flange diameter allows for shorter spoke lengths, which creates a stiffer, more responsive wheel. This is particularly important for fat bikes, where the large tire volume can otherwise lead to lateral flex during cornering or technical riding.

The shell is machined from a single forged aluminum billet rather than being cast or welded. This process maintains the structural integrity of the metal, resulting in a hub that is exceptionally strong and resistant to the stresses of rugged terrain.

Yes, the hub uses sealed stainless steel cartridge bearings. These are designed to keep out grit, mud, and water, ensuring the hub continues to spin smoothly even after exposure to harsh riding conditions.

The Fatsno uses a standard 6-bolt disc mount, which is compatible with the vast majority of mountain bike disc brake rotors on the market.
