The Fox DPX2 With the ShockWiz Suspension Tuner Reveals a LOT of information!

After several months spent on Peavine Peak in Northern Nevada, I have been able to come to several conclusions about my Fox DPX2 Rear Suspension. To review; I have a 2012 Trek Superfly 100 Pro, with just 100mm of rear travel. The front fork is a 2020 Fox 32. When I used the ShockWiz Tuner on the fork, I was able to add spacers and adjust the air until I consistently got about 96 points out of 100 possible points on the ShockWiz app. It DID make a difference in my confidence, competence and comfort when riding.

However, the rear shock, a 2012 Fox RP23, was unable to keep up with the demands of my riding. Therefore, in March of 2021, I replaced the RP23 with a Fox DPX2.

Don’t Use the ShockWiz for just one ride. Use it for a LOT of rides.

The Shockwiz from Quarq is designed to measure compression and rebound via air pressure. I THINK it also looks at G forces, compression and rebound velocity, preload, and time spent airborne. My goal for this experiment was to try and stick to trails that I know, and to be as consistent with the bike and my cycling as possible. I chose the local XC race course as my primary loop. I also performed several shorter loops and a few out-and-back rides, to challenge myself and the rear shock.

One ride alone will give some information, but it is in detecting a long-term TREND from cycling that can determine just how best to tune the DPX2. I chose the DPX2 because it IS infinitely adjustable for compression, rebound, air pressure, and volume. It can also run different oil densities.

The Results

After 18 rides of at least one hour, the ShockWiz Suspension Tuner revealed two major issues that I believe need to be tweaked, but again, I will not perform these tweaks until I earn 20 rides.

Here’s a video with my results so far. Enjoy!
