Our aluminum headset spacer kit is a universal kit designed to allow you to eliminate your OEM headset on your Surron, Talaria or E-Ride PRO without cutting your head tube. The kit includes four different spacer sizes (5mm, 10mm, 15mm, 20mm) giving you multiple options to fill in the stock head tube height or alternatively if you decide to cut your head tube the shorter spacers can be used to fine tune your installation.
