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

*OIL NOTE: Sirris uses Shell Tellus S2 VX15 (5wt) in the fork cartridge and Shell Tellus S2 VX68 (20wt) as the bath oil. These are cross compatible with other high quality 5wt and 20wt suspension fluids. Sirris uses a semi-synthetic 2.5wt oil in the shock that is also compatible with other high quality 2.5wt aftermarket suspension fluids. You can use 5wt/20wt oils of your preference, Lubefinder.com can be used to source the fork oils. KYB K2C can be used in the shock and has wide availability.
