The Shimano HB-TX505 front disc hub is the perfect blend of affordability and durability—engineered to meet the everyday demands of mountain bikers, trekking riders, and city commuters alike. As part of Shimano’s reliable and cost-effective TX series, this hub delivers consistent performance in all conditions while maintaining the brand’s signature engineering precision and serviceability.
Designed for bikes equipped with disc brakes, the HB-TX505 features Shimano’s CENTER LOCK rotor mount system, allowing for fast, secure, and tool-efficient rotor installation using a spline interface and lockring. This system not only streamlines maintenance and wheel setup but also ensures precise rotor alignment, reducing braking noise and improving braking consistency over time.
At its core, the HB-TX505 is built around Shimano’s proven cup-and-cone bearing system, renowned for its smooth rolling characteristics, excellent load distribution, and easy maintenance. Unlike sealed cartridge systems, cup-and-cone bearings allow for micro-adjustments and are easily serviceable—perfect for riders who want their hubs to last season after season without performance loss.
The hub shell is made from forged aluminum, striking a balance between strength and weight, while the quick release (QR) axle system provides universal compatibility with 100mm fork spacing—a standard for most front suspension and rigid MTB or trekking forks. The skewer system is robust, reliable, and easy to use, making wheel installation and removal quick and tool-free, whether on the trail or at home.
What truly makes the HB-TX505 stand out is its ability to bring Shimano-level quality to entry-level and mid-range builds, offering the performance and dependability typically reserved for higher-end components. It’s a smart upgrade or replacement option for riders who expect more from their gear but want to keep their budget in check.
