The most notable upgrade to the Fox RP23 shock range is the Adaptive Logic external compression-adjustment feature. The shock's ProPedal, anti-bob damping function is preset at a high level at the factory. Now, the ProPedal lever simply switches from no platform to the preset level. The external Adaptive Logic dial gives RP23 owners adjustable low-speed compression damping - an important function that has been missing since the original RP3's debut. This tuning option should be a plus for every rider, especially jumpers, who often crank up the shock's compression damping to mute bad landings. Watch the video for the whole story:
We think Fox's new RP23 with Adaptive Logic could give aggressive riders a lighter-weight alternative to a DH-type piggyback damper or a simple coil-over shock. Any thoughts?
On the 2012 shock they're introducing at SeaOtter, the 2 part of the name, the blue lever on the shock, one position is the firmest pro-pedal setting and the 3 part is the blue dial which controls the so-called Adaptive Logic adjustment range setting. And the three options on its dial, which are labeled 0, 1 and 2 with 0 being open and the 1 and 2 are levels of LS damping adjustment below the 3 and above the 0 setting.
Or did everyone just skip reading the original heading where it says...
"2012 Fox RP23 - Sea Otter Tech 2011 "
Really the problem can be traced to the author, this is R.C. afterall, former editor of Mountain Bike Fiction... who for a former bike designer apparently is really out of date in shock technology, because the past years RP23s DID in fact have LS damping adjustment options contrary to what he chooses to write above. ProPedal is just fox's tradedmarked name for the seperate LowSpeed damping circuit they build into their shocks.
0: 2011 propedal switch off = 2012 Adaptive on, position 0
1: 2011 propedal on, position 1 = 2012 Adaptive on, position 1
2: 2011 propedal on, position 2 = 2012 Adaptive on, position 2
3: 2011 propedal on, position 3 = 2012 Adaptive off.
deeeights point is that there are four positions of compression damping on both, so no real change.
The Fox guy says that "when you flip the switch, you can change the level of low speed compression damping", which means that even in the lowest setting in Adaptive mode, there is still low speed compression damping. I recently deformed a shim on my 2011 RP23, and there was no compression damping at all. Once Fox repaired it, with Propedal off, there was a noticeable increase in compression damping. I think deeeight is correct, since ProPedal is merely a name for low speed compression damping, and low speed compression damping still exists in the 2011 'Off' position, and in deeeights model, '0' simply represented the lowest LSC setting. Deeeight was simply using 0-3 to illustrate that there is no real change, only in what is accessed quickly by flipping the switch.
2011: PP on = 1,2,3
PP off = 0
2012: PP on = 3
PP off = 0,1,2
