1-1/8" - 1.5" Headset (ZS44/28.6 UPPER and EC44/40 LOWER)
We manufacture our headset out of US-produced 7075 aluminum. Each headset is machined in-house to the same high quality standards we apply to all of our products. Each of our 1-1/8" - 1.5" headsets comes with a color matching 5 mm transition headset spacer. We engrave our script “Phil” into each stem cap and hand paint them just like our hubs.
