Propedal and compression damping on the Float R can be changed by adding or removing belleville washers and making up the resultant stack height by adding or removing the spacer washers. I’m pushing out the setup anyway because I need a benchmark to compare suspension setups too in simple terms like softer or stiffer than the baseline. The amount of pre-load can be externally adjusted. I multiply that number times 25. When set wide open a huge amount of flow is allowed past the main shim stack, hence the damper has a huge HUGE range of damping force available. 050 shim was too thick, even with a set of new pushrods. Ideally, with the right shim stack, the best fork will not have any bleed that is not managed via the shim. The cone valve allows unlimited opening, so harshness of the suspension is reduced, while the closed cartridge construction ensures reduced friction, consistent performance over longer periods and.
