Surly Ultra New Disc Hub – Durable Bike Hub with Quick Release Conversion

The Surly Ultra New Disc Hub represents a significant advancement in hub technology, designed for cyclists who prioritise reliability, durability, and ease of maintenance. Crafted with a robust 6061 T6 forged and machined aluminium alloy shell featuring medium-height flanges, this hub combines classic strength with modern innovation. Its hollow axle design and thread-in wheel fixing bolts enable a seamless conversion between bolt-on and quick release configurations without requiring additional tools or complex modifications, making it an adaptable choice for a variety of cycling setups.

Engineered with high-quality CroMoly steel axles and 10.9 stainless steel fixing bolts, the Ultra New hub delivers exceptional strength and corrosion resistance, ensuring long-term performance even in challenging conditions. The knurled stainless steel bolt caps and cone nuts provide secure wheel retention, preventing slippage under demanding use. Interlocking cones and dust caps contribute to axle stiffness, while the non-adjustable 6901 bearings guarantee smooth and reliable rotation. This combination of features simplifies installation and maintenance, allowing riders to focus on their journey with confidence.
