Product Details

Overview & Technology

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.

Key Features

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.

Fit & Compatibility

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.

Who It's For

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.

Frequently Asked Questions

What frames use the ZS56/40 lower?

Any modern mountain frame specified for a ZeroStack lower with a 56mm cup seat and a 40mm crown race will accept this part. Check your frame's headset spec or measure the head tube ID to confirm ZS56 compatibility.

Can I convert this lower to fit a different steerer or top?

Yes. Cane Creek offers conversion lower variants (for example ZS/56/30/H4) and a range of tops. Mixing and matching tops and bottoms lets you adapt stack height and steerer interfaces to your fork and frame.

How do I install and set preload on this headset lower?

Install the lower cup into the head tube using a cup driver sized for ZS56 and press it squarely. Fit bearings and crown race, then assemble the upper parts and preload using the top cap to remove play before tightening the stem to the manufacturer's torque specs.

What maintenance does the 110 Series bottom require?

The sealed cartridge bearings require minimal maintenance — periodic inspection and replacement when you detect play or roughness. If water or mud intrusion occurs, remove, clean, and re-grease the interface; bearings are user-replaceable for long-term serviceability.

Is this lower compatible with tapered forks?

Yes. The ZS56/40 lower is designed to accept forks with a crown race diameter of 40mm, which covers many tapered fork designs. Always confirm your fork crown race Ø and steerer dimensions before installation.

What's the weight and finish of this part?

The listed Cane Creek ZS/56/40/H4 lower assembly is approximately 53.8g in black anodized aluminum. Conversion variants (ZS/56/30/H4) are listed around 61.3g, depending on configuration.

Buying Guide

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.
