VP Components VP-Z104PE 1-1/8" Semi-Integrated Headset - ZS44 - Black

ZS44/28.6 | ZS44/30 | 44mm Head Tube | Caged Bearing | MTB, Hybrid, Commuter, Kids Bike

A reliable semi-integrated threadless headset from VP Components - a major Taiwanese manufacturer that supplies OEM headsets to bike brands worldwide. The VP-Z104PE is a straightforward, well-made replacement headset for any bike with a 44mm zero-stack (ZS44) head tube and a 1-1/8" fork steerer. This is the most common headset standard found on MTB, hybrid, commuter, and kids bikes built from the mid-2000s onwards. If your current headset is worn, pitted, or missing, this is a direct bolt-in replacement for the vast majority of bikes in this category. The 10-piece kit includes everything needed for a complete installation.

Compatibility

✓ COMPATIBLE WITH:

• Frames with a 44mm ZS (zero-stack/semi-integrated) head tube bore
• 1-1/8" threadless fork steerers (28.6mm) - the standard size on most MTB, hybrid, commuter, and kids bikes
• Mountain bikes, hybrid bikes, commuter bikes, trekking bikes, kids bikes with the above head tube standard

✗ NOT COMPATIBLE WITH:

• Tapered steerer forks (1-1/8" to 1.5") - these require a tapered headset with different lower cup sizing
• External cup (EC) head tubes - EC head tubes have a smaller bore and use cups that sit outside the frame rather than recessing inside it
• Integrated head tubes - where bearings sit directly in the frame without cups
• Threaded (quill stem) forks - this is a threadless headset only

Not sure if this fits your bike? Check your frame's spec sheet for the head tube standard, or measure the internal diameter of your head tube. A 44mm bore indicates ZS44 compatibility. Feel free to message before buying if unsure.
