All MagCAD headset parts are 3D printed in a durable Nylon to ensure they are robust to many years of use. As with any steering related components they should be installed by a competent mechanic and inspected regularly. Incorrect assembly or mis-use may result in damage to the headset components and/or injury.
Particular care should be taken to ensure the internal cable routing is installed correctly and checked periodically.
The MagCAD Top Bearing Cover in this kit has a stack height of 13.2mm, approx. 2mm less than the OEM Allez Sprint Bearing Cover that is to be removed. Coupled with the 4mm top spacer this makes for a minimum stack height of 17.2mm. The remaining spacers in the kit total 25mm in height, equating to a total supplied stack height of 42.2mm. Spacers can be removed or added to tailor the handlebar height to your exact needs.
Additional 10mm and 5mm spacers can be purchased separately should they be required.
