Product Details

Overview & Technology

The Cane Creek 110 Series Top ZS44 is engineered as a premium upper headset top for ZeroStack (ZS44) frames. It combines CNC-machined aluminum construction with sealed cartridge bearings to deliver low friction, long-lasting performance and clean aesthetics. Available as an individual top assembly, the 110 Series lets you mix-and-match tops and bottoms to suit straight or tapered fork configurations. Materials and construction: The top uses precision-machined aluminum cups with a durable anodized finish and matched sealed cartridge bearings. The bearings are sealed to keep grit and moisture out, while precision races and tight tolerances reduce play and deliver consistent, predictable steering feel over time.

Key Features

Performance-focused components: The 110 Series Top features sealed cartridge bearings for smooth rotation and low maintenance, plus an optimized seal profile to resist contamination on dusty, wet trails. Choose the H8 (short) or H15 (tall) stack-height cap depending on headset preload and spacer needs. • Sealed cartridge bearings: Corrosion-resistant sealed units for durable, predictable steering. • CNC aluminum cups: Lightweight, stiff construction with a hard-anodized finish for wear resistance. • ZeroStack (ZS44) interface: Fits frames with a 44mm upper bore and 28.6mm (1‑1/8") steerer. • Two stack heights: H8 (~52.9g) and H15 (~60g) let you fine-tune bar height and spacer layout.

Fit & Compatibility

The SHIS designation ZS44/28.6 means this top is designed for frames with a 44mm upper headtube bore and a 28.6mm (1-1/8") steerer. It works as the upper half of a ZeroStack headset. For tapered forks (1.5" to 1-1/8"), choose a compatible 110-Series bottom assembly or conversion cup to match your lower bore and steerer diameter. Mix-and-match flexibility: Cane Creek sells tops and bottoms separately—install this top with EC/IS/ZS bottom options to build a headset that fits nearly any straight or tapered configuration. Always verify your frame's upper bore and steerer diameter before ordering; use correct crown races and torque settings during installation.

Who It's For

This top assembly is aimed at mountain riders who want a premium, low-maintenance headset upgrade or replacement. If you demand smooth, reliable steering on trail, enduro stages, or aggressive XC runs, the 110 Series Top gives a durable bearing platform that reduces play and resists contamination. It's also ideal for mechanics, frame builders, and riders who value component-level customization—buy the top independently to pair with the exact bottom that matches your frame and fork combination.

Frequently Asked Questions

What does ZS44/28.6 mean and will this fit my bike?

ZS44/28.6 indicates a ZeroStack upper for frames with a 44mm headtube bore and a 28.6mm (1-1/8") steerer. Measure your frame's upper headtube bore and your fork steerer diameter—if they match, this top will fit. For tapered forks you must pair this top with the correct bottom assembly or conversion cup.

Can I use this top with a tapered 1.5" lower steerer?

Yes—if you pair this ZS44 upper with a compatible bottom assembly or conversion cup designed for your lower steerer (for example an EC or IS bottom that accepts a tapered fork). Cane Creek's 110-Series bottoms cover most lower-bore and steerer combinations.

How do sealed cartridge bearings compare to loose bearings?

Sealed cartridge bearings are preassembled, sealed units that require less maintenance and provide consistent preload and rotation compared with loose bearings. They are easier to replace when worn, but the cartridges themselves are typically not serviceable—swap the cartridge when performance declines.

Which stack height should I choose, H8 or H15?

Choose H8 (short) if you want a lower stack profile and minimal topcap protrusion; choose H15 (tall) if you need extra spacer height or prefer the taller cap for headset preload distribution. Check your stem clamp area and spacer availability to decide which gives the best bar height and cable routing.

Can I service or rebuild the bearings?

The 110-Series uses sealed cartridge bearings which are not intended to be disassembled for service. When bearings become gritty or loose, replace the cartridge units with Cane Creek replacement bearings to restore smooth operation.

What tools and torque specs are needed for installation?

Typical installation requires headset press tools or a shop press for cups, a crown race setter, and an Allen key for topcap preload. Tighten topcap preload bolts to the stem manufacturer's recommended torque—usually around 2–4 Nm for the compression bolt—and follow Cane Creek's installation instructions for cup press tolerances.

Buying Guide

When buying an upper headset top assembly, first verify your frame's headtube bore and steerer diameter—SHIS codes like ZS44/28.6 remove the guesswork. Decide whether you need a short or tall cap (H8 vs H15) based on spacer needs and stem clamp height. Sealed cartridge bearings are the easiest long-term choice for riders who prefer low maintenance and predictable steering feel. Also consider construction and finish: CNC-machined aluminum tops offer a strong, lightweight platform and a clean look. If your frame uses a tapered fork, plan the matching bottom assembly or conversion cup at the same time to ensure proper bearing alignment and preload. Finally, factor in replacement bearing availability so you can refresh the headset when needed instead of scrambling for parts down the road.
