SPARK Expander

Like many other expander bungs, the SPARK expander fits inside the fork steerer tube and gives the stem clamping area some reinforcement for safe stem installation, it also allows the secure compression of headset bearings when the steerer top-cap is screwed into it. But, unlike a lot of other compression bungs, it features a channel running through it that aids the routing of dynamo power cables, which then exit through the port in the top cap to provide a neat solution to powering lights and devices.
