System Front Disc Hub — 20x110mm

Product Overview

The System Front Disc Hub is a modern front hub designed for 20mm thru-axle frames with disc brake systems. The 110mm spacing accommodates contemporary BMX and all-mountain geometry. Sealed bearing construction with aluminum shell delivers durability and smooth rotation for street, park, and mixed-terrain riding.

Key Features

• Aluminum hub shell – Lightweight aluminum body reduces rotational mass while maintaining structural integrity. Durable alloy resists corrosion and maintains finish through extended use.

• Sealed cartridge bearings – Precision sealed bearings resist dirt and water intrusion, extending service life and reducing maintenance. Cartridge design provides smooth rotation without play or drag.

• 20mm thru-axle compatibility – Modern thru-axle standard provides rigid, tool-free quick-release functionality. 20mm diameter delivers increased lateral stiffness compared to traditional quick-release hubs. Thru-axle sold separately.

• 110mm hub spacing – Standard modern spacing accommodates contemporary BMX and all-mountain frames with updated geometry. Works with frames designed for 20mm thru-axle compatibility.

• 6-bolt rotor mounting – Standard disc brake rotor interface compatible with modern hydraulic and mechanical disc brakes. Allows precise rotor alignment and secure attachment without post-mount adapters.

• 32-hole lacing pattern with 14-gauge spokes – Standard wheel lacing accommodates all rim and spoke combinations. 14-gauge spokes provide adequate tension and stiffness for wheel durability.

• Reliable performance – Sealed bearing and aluminum construction combine for dependable operation across varied riding conditions and disciplines.
