Product Details

Overview & Technology

The Cane Creek 110 Series Bottom IS52 is engineered to deliver premium performance for modern integrated mountain frames. Built around a sealed cartridge bearing and a 52mm lower cup, this lower assembly balances durability, low friction and ease of service in a compact aluminum shell. The 110 Series uses optimized seals and precision-machined aluminum components to protect the bearing from grit and moisture while keeping rolling resistance low. Cane Creek offers modularity — buy complete assemblies or mix-and-match tops (short 9mm or tall 15mm) and bottoms to suit straight or tapered steerer configurations.

Key Features

Materials and construction: the lower cup is machined from lightweight aluminum for stiffness and corrosion resistance, paired with a high-quality sealed cartridge bearing for consistent performance. Technical highlights include:• Sealed cartridge bearing for predictable, low-maintenance operation • 52mm lower cup (IS52) compatible with IS52/40 SHIS frames • 40mm crown race diameter for secure fork interface • Available conversion variant (IS/52/30) for alternate crown race setups

Fit & Compatibility

The 110 Series Bottom IS52 is an Integrated (IS) lower designed to fit frames specified as IS52/40 in SHIS sizing. It accepts a 1-1/2" tapered steerer when paired with the correct top assembly and crown race — the lower crown race diameter is 40mm. Because Cane Creek sells tops and bottoms separately, you can create the exact headset stack height you need. Choose short (H1 — 9mm) or tall (H1 — 15mm) tops and conversion bottoms (IS/52/30) for frames or forks with non-standard crown race interfaces.

Who It's For

This lower headset is aimed at mountain bikers who want a reliable, serviceable integrated headset without overspending on flagship materials. It's especially useful for riders upgrading worn lower cups or building a bike around modern IS52 frames and tapered forks. Mechanics, home wrenchers and builders who value modularity will appreciate Cane Creek's ability to mix tops, bottoms and conversion parts to suit headtube tolerances and personal stack-height preferences.

Frequently Asked Questions

What frames does IS52/40 fit?

IS52/40 fits frames that use the SHIS integrated lower cup standard with a 52mm outside cup diameter and a 40mm crown race interface. Check your frame's headtube spec or measure the lower headtube bore to confirm compatibility.

Can I use this with a tapered 1.5" steerer?

Yes — the 110 Series bottom IS52 is intended for modern tapered setups when paired with the correct top assembly and crown race. Ensure you choose a top section that supports a 1-1/2" (1.5") tapered steerer and match the crown race diameter.

How often do the sealed cartridge bearings need replacing?

With normal mountain use, sealed cartridge bearings typically provide months to years of reliable service. Replace them when you notice play, roughness, or increased friction. Because they’re sealed cartridges, replacement is straightforward and inexpensive.

What tools do I need for installation?

Install with a headset press specific to integrated cups and a crown race setter for the 40mm race. Torque the compression cap and stem to manufacturer specs. Avoid hammering cups directly — use a proper press to prevent damage.

Can I mix this bottom with Cane Creek tops?

Yes. Cane Creek designed the 110 Series to be modular: you can pair this IS52 lower with short (9mm) or tall (15mm) tops, or with conversion tops, to tailor stack height and compatibility for your frame and fork.

What’s the difference between IS/52/40 and IS/52/30?

IS/52/40 refers to a lower cup with a 40mm crown race diameter; IS/52/30 is a conversion bottom designed for forks or crown races with a 30mm interface. Choose the variant that matches your fork’s crown race diameter.

Buying Guide

When selecting a lower headset assembly for an integrated frame, start by confirming your frame’s SHIS size (IS52/40 for this part). Measure the headtube bore and verify your fork crown race diameter — the 110 Series bottom comes in IS/52/40 and a conversion IS/52/30 variant for different crown race sizes. Choose a top that matches your desired stack height (short 9mm or tall 15mm) and steer toward sealed cartridge bearings if you prioritize low maintenance and predictable performance. If you’re unsure, bring measurements to your local shop — correct installation tools are essential for longevity.
