Sirris R46 Shock Springs

Shock springs for the Sirris R46 Shock for SurRon Ultra Bee. When upgrading your bike with a larger battery, we recommend going up one spring rate to accommodate the heavier bike weight. SurRon Ultra Bee shock springs require a spring compressor because of the short shock length.

Max preload = 20mm
