Right time to explain things badly. The RP23 has pre/factory set velocity (compression) and rebound settings.
For velocity/compression do the stickers show Low-medium-fast velocity shaft speed due to leverage ratio, for example 2:1 would be fast, 2.5:1 medium and 3:1 slow for a given frame travel. As a result the 2:1 ratio needs less compression damping and the 3:1 ratio needs more damping as it has to dissipate the energy over a shorter distance. Giving: Low is high compression – medium is medium – fast is low compression.
Or is it actually compression tune and not velocity so Low-medium-firm compression damping? In which case why call it velocity tune?
For rebound is it low-medium-fast rebound velocity or low-medium-firm rebound damping?
Can’t work this out and could do with a new shock. I could just go med-med but where is the fun in that.
