Product Details

Overview & Technology

The Cane Creek 110 Series Bottom EC44 is a premium external lower cup designed to convert compatible head tubes to a 1-1/2" steerer standard while maintaining a slim stack profile. Built around sealed cartridge bearings and precision-machined aluminum, this conversion bottom gives smooth, predictable steering and long-term reliability on demanding mountain trails. Engineered with an EC44/40 SHIS fit, a 44mm lower cup and a 40mm crown race diameter, the 110 Series prioritizes durability and low maintenance. Cane Creek pairs effective seals with tight tolerances to keep grit out and grease in, giving consistent performance ride after ride.

Key Features & Construction

The 110 Series Bottom EC44 uses high-grade aluminum for the cup and a sealed cartridge bearing for the interface. The sealed bearings provide low friction and simple servicing—replace cartridges easily without pressing bearings in and out of the frame. The result is a dependable steering feel with minimal play over time. Construction highlights: • Sealed cartridge bearings for predictable, low-maintenance steering • Machined aluminum cup for strength without excess weight • Effective seal geometry to resist water and dirt intrusion

Fit, Compatibility & Installation

This unit is an external, threadless lower (SHIS: EC44/40) intended for frames with a 44mm external lower cup seat and a 1-1/2" tapered steerer. The crown race diameter is 40mm, so it pairs with forks that have a 40mm crown race seat. Stack height is 12mm, making it compatible with many Cane Creek 110 tops and third-party tops of similar stack profiles. Installation is straightforward: press the lower cup into the head tube to specification, install the crown race to the fork, then fit the compatible top cap and stem. When swapping tops and bottoms, confirm SHIS codes (EC44/40 lower) and steerer size to avoid fit issues.

Who It's For

Designed for mountain riders, builders and mechanics who need a robust lower conversion for tapered 1-1/2" steerers. It's ideal if you want the reliability of sealed cartridge bearings with the flexibility to mix and match Cane Creek tops and bottoms for custom stack heights. If you ride aggressive trail, enduro or bike park terrain and demand low-maintenance performance from your headset, the 110 Series Bottom EC44 is a compact, durable solution that keeps the front end precise and confidence-inspiring.

Frequently Asked Questions

What frames and forks is this lower compatible with?

The 110 Series Bottom EC44 is SHIS EC44/40: it fits frames with a 44mm external lower cup seat and pairs with forks that use a 40mm crown race. It's intended for tapered steerers that finish at 1-1/2" at the crown.

Can I service the bearings or do they need replacement?

This product uses sealed cartridge bearings designed for minimal maintenance. When the bearing wears, you replace the cartridge rather than regreasing and repacking—making service quick and precise.

Will this convert my head tube to accept a 1-1/2" steerer?

Yes. As a conversion lower, it enables external cup head tubes with the correct seat diameter to work with 1-1/2" tapered steerers. Confirm your frame's lower cup seat diameter is 44mm before purchasing.

How do I choose the right top to pair with this bottom?

Choose a Cane Creek 110 Series top or compatible top with matching steerer size and desired stack height. The 110 Series offers short (9mm) and tall (15mm) tops—select based on headtube length and headset stack preferences.

What tools are required for installation?

You need a headset press (or appropriate cup drift), crown race setter, torque wrench for stem bolts, and basic hex tools. Precise pressing and correct torque are important to avoid damage and ensure proper function.

Is this suitable for eMTB or heavier bikes?

Yes—while designed for mountain bikes broadly, the aluminum cup with sealed cartridges provides robust performance. For very heavy or extreme eMTB applications, verify bearing spec and consider more heavy-duty bearing options if recommended by the frame or fork manufacturer.

Buying Guide

When choosing a lower headset or conversion like the Cane Creek 110 Series EC44, verify the SHIS standard of your frame (EC44/40 here) and the crown race diameter required by your fork. Decide whether you need a lower-only conversion or a full headset; mixing Cane Creek tops and bottoms gives flexibility on stack height and steerer size. Prioritize sealed cartridge bearings for easy serviceability and predictable steering feel. Consider intended use—aggressive mountain or enduro riding benefits from robust seals and precision machining to keep contaminants out and reduce headset maintenance intervals.
