Cane Creek 110 Series Bottom ZS56

The Cane Creek 110 Series Bottom ZS56 is a precision lower headset assembly engineered for modern mountain bikes. Built around sealed cartridge bearings and a 40mm crown race diameter, this ZeroStack (ZS56/40) lower provides smooth, durable steering with minimal upkeep.

Materials and construction emphasize reliability — machined aluminum cups, tightly toleranced bearing seats and Cane Creek's proven seal architecture keep grit out and lubrication in. The 110 Series was designed to be mixed-and-matched: purchase complete assemblies or pair this lower with short (9mm) or tall (15mm) tops and conversion bottoms to suit your frame and fork.

Performance-driven details: sealed cartridge bearings reduce play and rolling resistance while simplifying maintenance. The aluminum lower cup balances stiffness and weight for dependable steering feedback without adding unnecessary mass.

• Sealed cartridge bearings for consistent feel and low maintenance.
• Crown race Ø40mm for accurate fork interface and secure fit.
• ZeroStack ZS56 lower cup fits common modern mountain head tubes.
• Conversion-ready variants available (ZS/56/30) to adapt to different steerer standards and headset tops.

This lower is SHIS ZS56/40 — that means the head tube ID accepts a 56mm underside cup and the fork crown race uses a 40mm diameter. It accommodates 1-1/2" steerer tubes and works across most modern mountain frames that specify a ZS56 lower.

Because Cane Creek offers interchangeable tops and bottoms, you can pair this lower with Integrated (IS) or External Cup (EC) conversion tops, and choose short (9mm) or tall (15mm) stack-height tops. Available variants include ZS/56/40/H4 and the conversion ZS/56/30/H4 for frames or forks that require alternate stack geometry.

Designed for mountain riders who want a reliable, service-friendly headset lower that handles trail, enduro-style abuse and daily riding—without fuss. Builders upgrading to a premium sealed cartridge lower or mechanics replacing a worn lower cup will both benefit from the 110 Series’ durability and interchangeability.

If you run a modern mountain frame with a ZeroStack lower cup and you value easy maintenance, precise steering, and the flexibility to convert steerer or stack options, this lower is an excellent choice.

Choosing the right headset lower for a mountain bike starts with SHIS sizing: confirm your frame uses a ZS56 lower seat and check your fork's crown race diameter (40mm is common). Decide whether you need a conversion lower (e.g. ZS/56/30) based on your fork and whether you'll pair it with short or tall tops to achieve ride height and cable/clearance needs.

Prioritize sealed cartridge bearings for low maintenance on trail bikes; aluminum cups offer a good balance of stiffness and weight. If you service your bike regularly, choose a headset with user-replaceable bearings and widely available conversion options like the Cane Creek 110 Series.
