The two shocks were tested in the open mode. The levers are just clocked slightly different between the two shocks.

As for the compression question, we're essentially opening up both compression circuits. So it will be lighter that the stock tune with the adjuster fully open. Obviously the compression tune depends on the rider weight and riding style. In most cases, you'll continue to run the compression fully open and use the air pressure and volume spacers to get the support you need. This helps maintain the suppleness. It's not likely that you would need to use the LSC compression adjustment. So for example, if you go from your normal trails to the bike park where the speeds and forces are typically a lot higher, you would add air pressure to get more support vs. adding compression which would ultimately effect the initial stroke sensitivity. Hopefully this addresses your question about having more support when you need it.

As for your rear shock, we can definitely tune that in a similar fashion as the DPX2 in the video. You can gain a lot of sensitivity out of the rear end with the coil spring out back, and the linear rate is much more supportive in the mid-stroke. The Bomber CR is a good shock for the money, but it's limited in tuning potential. We've seeing some issues with oil bypass in the Bomber CR that we didn't used to see with the Van R/RC. We're still searching for a really good, tune-able, coil shock option that also has a climbing switch. Since you already have the Super Deluxe, let's tune it...

Thank you so much for that response.

We totally agree, longer runs and more runs would have ultimately shown the difference. We may have tried to pack one too many things into this whole feature, which ultimately did not leave us enough time to do a proper timed test. If we had been able to do 3 or 4 runs on each setup and take the average, we're confident we'd see a bigger difference. Also with more time on a great setup, the confidence you find, will allow you to push much harder.

This is a question that we get a lot these days considering the mass offerings of coil spring conversions available on the market.

What we would say is that for a rear shock, the coil is a really great option. Rear air shocks require tight seals to be able to handle the air pressure, especially at full compression. This in turn creates at lot of extra friction on the entire system. With the coil spring, it alleviates a ton of friction, and gives you un-matched suppleness and mid-stroke support. The limitation of the coil spring has always been being able to find the exact right spring rate for every rider. Most riders find themselves between rates, and depending on riding style and preference they end up choosing between a spring that is either too stiff or too soft. In most cases, riders can get away with the stiffer rate because it's better for the overall suppleness than dialing in the preload. Sprindex adjustable coil springs may be changing the game on this front as far as dialing in your rate. We're looking forward to testing some of their springs here in the near future.

So, when it comes to forks, we're dealing with a totally different animal. Because of the design, especially self-equalizing air springs (Fox NA2 EVOl and RockShock Solo or DobonAir), modern forks do not require the tight seals that we see in rear suspension designs. So we ultimately have much less friction in the fork, freeing up the potential with tuning the air spring.

With coil conversions and coil fork offerings, the same issue we see with people being between rates on the rear shock, is even tougher with fork offerings. Most companies only offer 5, maybe 6 spring rates, which makes it even more difficult for riders to find the correct rate. In turn, the companies that are making these conversions and forks are improvising bottom-out mechanisms to essentially help keep people from hitting full bottom out when their spring is too soft.

The other issue with coil forks is that, instead of being on the outside of the rear shock body, the spring is confined to the inside of the fork stanchion. These fork springs are very long in comparison to a rear shock spring, so as the fork goes through it's travel, the spring needs room to move around, which adds more friction to the system. Visualize pushing rope. To be perfectly clear, coil forks can be a great option for some people, but the likely-hood of nailing the spring rate for the rider weight is slim.

So, with the RUNT, you can actually take the linear rate of a coil spring, and dial it in to the exact rate you need for your weight, riding style, preference, and the terrain you're riding. Depending on the accuracy of your shock pump, this means you can adjust the L chamber in 2.5 psi increments, which we have found makes a noticeable difference.

We have had a number of customers that are always trying the latest and greatest go from being on a RUNT, to trying numerous coil conversions, and ultimately ended up back on the RUNT for all the reasons above.

There is not enough room in the air chamber for both the RUNT and the Luftkappe. The RUNT provides excellent small bump compliance while also vastly improving the mid-stroke support of your fork’s air spring, giving it a coil-like feel. Both products do tweak the spring curve in different ways, so @b0bg is right in the fact that using both would not be beneficial even if there was room for both.

We had initial prototypes of the RUNT in 2012 and began selling them in regionally in 2014. We were not ready for the mass market until now, which is why you're just starting to see mainstream coverage.

I've been running one of these for about a month now. 170mm Fox 36 Grip2.

At 52psi (with no RUNT) it was Ok off the top but midstroke was too soft and I could never use more than about 150mm travel even on fairly hard hits.

With Runt:

No the Runt has two air chambers that are never in communication with each other. This is what allows it to be so adjustable.

Was it the DRCV shock that blew or was it the Full Floater that blew???
What came first ? We know the full floater link made for a very unsupportive wallowy midstroke and they are finally going away from it.

Airwreck, I believe I answered your question below. Yes It turns out smaller riders are much more sensitive compression damping stiction and higher initial pressures. We have actually changed tunes and reduced compression damping after working with smaller riders and found that the larger riders benefited from it just as much. This can be done with the runt because it has enough mid stroke support to keep your fork riding high in the travel with out being harsh.

It actually is more beneficial to smaller riders for the reason you just stated.

The Runt works on the concept of running lower air pressure and less compression damping. Resulting in a more supple fork.

The Mid stroke keeps it from feeling mushy when running lower pressure/less compression damping. Its a smooth transition and not stiff at all when starting with lower pressure.

The lower pressure does make it easier to get into the last third of the travel and its a smooth ramp to bottom out .

We dont like to see all the travel used regularly because what happens when you make a mistake come up short , over shoot a landing maybe land in a hole or on a rock? Typically we like to see about 25mm left over even after large jumps or drops on to smooth transition.

We set customers up this way and have been doing so for years. A few of them dont believe they will ever use full travel. However they always come back with story of almost having a really bad crash because of a mistake which eventually happens to every one. I dont care how good you are.

It usually goes something like ...... "I was riding along and I over shot a jump or came up short and thought I was done !!! But I rode away from it and sure enough I bottomed out the fork and was happy I had a little travel on reserve"

Yes we do. Your runt will ship with shims to get the appropriate rebound tune for your weight. Our instructions are posted on line to do so. We recommend running the compression all the way open. The runt has enough mid stroke support to keep your fork from diving. We don't need to rely on compression damping to do so, resulting in a more supple ride. If desired we can re-valve the upper base/compression valving to be even more supple on the charger 2( in house only).

Unfortunately, Rock Shox does not support the upper half of the charger 2 damper. They don't have replacement parts or directions for it. If something is done incorrectly it could mean having to purchase a whole new damper.

For that reason we only do compression valving in house. Rebound is easy to do If you are not equipped to adjust the rebound valving any good suspension /bike shop should be able to.

You can run the damper stock. We are just trying to make it as easy as possible for our customers to have the best riding fork possible.

You have it backwards. The longer the travel the shorter the runt . The shafts get longer when travel is increased so we have to make room for the longer shaft at bottom out. The 170 runt uses a 180 body with a stepped piston. The 160 runt is a longer body than the 180/170. To switch back and forth you would need two runts to keep the spring rates consistent.

You may want to try the 160 first. You might be surprised the runt gives you a much better quality of travel meaning it will ride higher and have good bottoming resistance while being supple initially. The better quality of travel will make it feel like it has more travel.

No, I have not seen anything published from PUSH or Vorsprung taking into account their air bump stop or hydraulic bottoming control valve. Our answer to this is simply adjusting the pressure in the High air chamber to adjust bottoming resistance. Most of our riders run what we recommend. The 2:1 ratio of air pressure gives you the most linear spring rate. For example: 50psi low, 100psi high

Some non-aggressive riders may run less in the High chamber so they can achieve full travel more often. Example: 50psi low, 80psi high

If needed you can run more pressure in the High chamber to make it progressive. Example: 50psi low, 100psi high
