Longer service life – thanks to high-grade steel construction
High-grade steel resists rust and surface wear, keeping bearing races smooth under repeated loads and rotation. Robust metallurgy reduces pitting and degradation over time.
Greater longevity lowers maintenance frequency and keeps steering predictable across many rides.
All-weather protection – with sealing rubber ring
A rubber sealing ring surrounds each bearing, forming a barrier against water and dust that can cause corrosion and accelerated wear. Sealed assembly limits contaminant entry while still allowing rotation.
Reliable performance in wet or dirty conditions, meaning less cleaning and fewer bearing failures.
Simple swap-in replacement – with 41.8mm external diameter and 45° angle
External diameter of 41.8mm combined with a 45° contact angle matches common headset specifications, enabling a direct-fit installation for compatible headsets. Standard dimensions avoid the need for machining or modification.
Quick, straightforward installation gets bikes back on the road without specialised tools for compatible setups.
