Yes, I hope I’ve understood correctly
2017 spring kit = coil replacement for air spring
Cartouche = replacement damper
Cartouche all in one = combined coil spring and damper
All I wanted was the coil spring Tom has been so pleased with, the damping cartridges are an unknown to me so I’d probably look somewhere more local for any upgrades/adjustment
Very helpful. So the spring kit is basically just a coil on the air side and the charger damper in a lyrik/pike remains on the other side. I guess the competitor to the spring upgrade is a luftkappe, but a spring seems like an inviting option.
