The Monarch Plus Debonair is indeed compatible with the Bottomless Rings shown in this feature.

Valid question. Answer here, in addition to some other neat comparisons to the previous Occam 29:

I'm impressed by your enthusiasm.

Re-read my comment with the graph. I don't disagree with you about how a volume change at the same starting pressure will alter the spring rate.

However, the slope (aka spring rate) does indeed change when you up the air pressure. Let's do some very basic math, using the nice orange and red dots at the 2-inch travel mark on the 4-inch chamber lines as an easy reference point.

Rise / Run = Slope

The 4-inch chamber with 200psi rises from 200lbs at 0-inches to 400lbs at 2-inches.
The 4-inch chamber with 100psi rises from 100lbs at 0-inches to 200lbs at 2-inches.

400lbs - 200lbs = 200lbs
200lbs - 100lbs = 100lbs

200lbs (rise) / 2in (run) = 100lbs/in
100lbs (rise) / 2in (run) = 50lbs/in

While they may look "more or less parallel," they're far from it.

It's true that lower travel Pikes need more tokens. There's a chart here that shows how many each fork can take: http://www.vitalmtb.com/photos/features/How-To-Get-The-Most-Out-Of-Your-RockShox-Suspension,9020/Slideshow,0/bturman,109

Don't be afraid to crank in that low-speed compression adjustment to help keep you higher in the travel. According to RockShox, "Low speed compression regulates oil flow in slow compression stroke speed scenarios such as rider weight shifts on the bike, and suspension compression during cornering or transitions." It also affects ride height, smoothness over small bumps, and traction.

After getting the air spring dialed in, if you feel like you're riding low in the travel, try increasing the low-speed compression by turning it clockwise (the direction of the plus sign) four clicks and repeating the test ride. If this was too much then turn back two steps counter clockwise.

If things don't feel smooth over small continuous bumps or if the front end has bad traction, back off the low-speed compression. Turn counter clockwise four clicks, then retest and make any correction two clicks at the time until you find that sweet spot. If you're unable to find it, chances are good that your air spring isn't set up just right for your terrain or riding style.

As always, when you think you've improved things, it's best to return to your original settings and double check. Be aware of other factors that can impact your ride like tire pressure, temperature, etc, to make sure they don't change things unexpectedly.

You can also chop the tokens in half if a full token is too much for you.

kc358, you've got some wires crossed. Changing air pressure does indeed change the spring rate. Here's a graph from RockShox to illustrate this fact:



Spring rate describes the stiffness of a spring and is defined as the (change in force) / (change in displacement). It's usually measured in lbs/in - the pounds of force necessary to compress the spring by one inch. In the graph, note the red and orange lines that represent different pressures in the same volume. In the case of the 100psi red line, we see a change in force of 100lb over 2-inches. The 200psi orange line sees a change of 200lb in those same 2-inches. If the spring rate did not increase as you increase pressure, the change in force over those 2-inches would be the same.

As you noted, almost all air springs have a progressive spring rate, which means that they get stiffer the more they are compressed. As you also noted, yes, changing the volume also increases the spring rate (note the red and blue lines and their respective 100lb increase vs ~200lb increase over 2-inches) - this is why many riders will reduce air pressure by a few psi as they add more Tokens in order to keep a similar sag level and initial stroke feel.

Yes, the force necessary to initially compress the air spring due to the static pressure (breakaway force) also increases as you up the pressure, but RockShox offsets this with their auto-adjusting SoloAir negative spring, The effect of the negative spring isn't shown in this graph, but the breakaway force is reduced by the amount of force created by the negative spring pressure.

Honestly, no one really complained about FOX's Float CTD rear shock. The majority of issues previously surrounded the Float CTD fork's lack of damping in the open mode, though this was resolved from model year 2014 forward. When you mention "setting up" the Monarch Plus DebonAir to perform well in one of three modes, are you talking about the air pressure?

From my experience (I'm testing one now), the Spartan isn't the best pedaling bike to begin with, regardless of shock settings. She's made to rally on the way back down.

Kfarm, cheers for the feedback. We wanted to focus primarily on getting the air spring and pressure dialed, because it's something many riders overlook and can have the greatest impact on your ride.

According to RockShox, "Low speed compression regulates oil flow in slow compression stroke speed scenarios such as rider weight shifts on the bike, and suspension compression during cornering or transitions." It also affects ride height, smoothness over small bumps, and traction.

After getting the air spring dialed in, if you feel like you're riding low in the travel, try increasing the low speed compression by turning it clockwise (the direction of the plus sign) four clicks and repeating the test ride. If this was too much then turn back two steps counter clockwise.

Congrats to hnzznh, the winner of the Leogang World Cup OTB contest and the SRAM X01DH drivetrain!

Of nearly 350 entries, 148 of you correctly guessed that both Aaron Gwin and Rachel Atherton would win. hnzznh’s predictions were off by a combined time of just 0.246 seconds. Nice work!

We'll have several more OTB contests throughout the season, so check back often.

Ha! You've clearly never seen Dave Camp ride.

For real though, have you ever been hauling along a new-to-you trail when it suddenly drops away into an unexpected tech fest? When you're really moving sometimes there isn't time to sit down, even if just for a split second.

Congrats to Alexwhite_scruz, the winner of the Fort Willian World Cup OTB contest and the SRAM X01DH drivetrain!

Of 287 entries, none of you correctly guessed that both Greg Minnaar and Rachel Atherton would win, forcing us to look for the next best prediction. Of the 38 of you that chose the next closest combo by picking second place Aaron Gwin and Rachel Atherton for the win, Alexwhite_scruz's winning time predictions were off by a combined 4.379 seconds. Nice work!

We'll have several more OTB contests throughout the season, so check back often.

Thanks for the heads up! We've added a link to their patent above. Shimano's motorized post is a great concept as well, although it requires a battery which is a bummer. One also has to wonder if a motor can also be fast and durable enough to be effective in a last second scenario.
