For as long as there’ve been multi-mode rear shocks with some manner of pedal platform, I’ve been trying to set up my shock for optimum performance in “Pedal” mode. My thinking was, by running it in the middle setting, I could keep the shock ready for anything. Switch it one way to climb and the other to descend. In reality, that might just have been limiting the performance of the shock, not letting me get the most out of it.
Since all manufacturers suggest setting sag with the shock and fork in full open (or Descend, etc.) mode, it stands to reason you’re setting it up to perform best in that position, right? We asked Duncan Riffle (SRAM MTB marketing manager and former 2x Nat’l DH Champ), Eric Porter (veteran pro MTB’r, now riding for Manitou), Mark Fitzsimmons (Fox Racing Shox’s pro athlete suspension tuner) and Josh Coaplen (Cane Creek’s VP of engineering).
First up, a little clarification of what exactly we’re talking about: When you’re setting your fork or shock to a particular mode (open, descend, trail, pedal, climb, whatever), you’re changing the low speed compression. For Fox forks, that means anything in the zero to five inches per second compression speed. Other brands are likely similar. This affects the suspension’s performance when you’re braking (at the fork), pedaling hard or while standing, railing corners and rollers and anything else that’s not a quick hit or hard landing. Those quicker, bigger hits are controlled by your high speed compression, and most products out there have fixed high speed circuits that are not easily user tunable. Cane Creek’s Double Barrel is the obvious exception.
We started this series with a look at setting your sag properly in Part One, now it’s time to tune those compression settings…
