The HCR (Hidden Cable Routing) stem is designed for road and gravel bikes that use internal headset cable routing. The HCR system hides the brake hoses from view without fully enclosing them in the stem or spacers, allowing for easier installation, maintenance, and travel. With its easy-to-use and fully sealed design, the HCR stem delivers the clean look of internal routing without the downsides often associated with it.Forged and Machined 6066 Aluminum construction with stainless steel hardwareDesigned to be used with the HCR (Hidden Cable Routing) system components, sold separatelyOne-piece, machined aluminum HCR headset spacers included with stem (1x10mm, 2x5mm)Optimized for wireless drivetrains, compatible with mechanicalItem SpecificationsBar Clamp Diameter (mm)31.8ColorBlackDefined ColorBlackLength100MaterialAluminumS.H.I.S.
