What about 1/2 of an ELEVENSIX? So only 1 compression circuit and maybe cheaper? Thoughts?

Thanks for taking the time for this! I've been watching lots of bikes come through but you're still teasing the Slayer. Got an eta on when I can order one up? Got any tips for someone who's struggling to setup their suspension? On a super deluxe and Lyrik RCT3 and still can't get it right.

Sweet!

That's correct, I have the 770 build for the slayer. I guess I'm struggling the basics. I understand setting up the sag but tweaking the rebound and compression seems like some voodoo magic.

We're a big believer of our Dual Overhead Valve Technology so I'm not sure you'll see us go down that road.

From a previous post on page 1:

1. Spring. Your spring rate controls ride height and bottoming and should be set with your compression set soft and your rebound set fast. While sag is a great starting reference, the overall ride quality should ultimately determine your final air pressure/volume/coil spring rate.

2. Compression. Compression damping controls the suspensions characteristic when it comes to things like brake dive, cornering performance, and pedal induced movements.

3. Rebound. How much rebound control is necessary is determined by how much your fork or shock is compressing so it should be set last. Rebound damping also has the largest effect on rider comfort at the handlebar or feet, so having your spring rate and compression optimized first will allow you to achieve the largest level of comfort and control from your rebound setting.

Following this order should keep you on track and reduce the chances of misdiagnosing your setup.


The shortcut is to outfit your bike with a custom tailored and setup ELEVENSIX with a matching ACS3 kit for the front fork! Smile

Realize I’m late to the party but hoping for some advice. Large rider, 230lbs, and wanting to run coil on a 29er enduro/trail bike. What are some models best suited for a coil shock and heavy rider?

Something with a progressive shock rate and a longer shock with a longer stroke.

You can’t be a mountain bike suspension nerd and not know about PUSH. Darren Murphy started PUSH in the early 2000’s focusing on suspension services and product upgrades that would give the common rider world-class performance. Over the years, PUSH has expanded its Loveland, Colorado, facility and finally created their first shock, the Elevensix in 2015. Since then they've refined the shock and now offer their ACS3 coil conversion kits for FOX and RockShox forks.

Ask Darren your questions below and he'll do his best to answer them throughout the day!

Hi Darren,

I have recently installed the 11-6 to my 2017 (w/2018 flip chip) Sworks Enduro 29 and couldnt be happier with the new coil. In fact, the planted ‘feel’ of the rear end and the confidence it inspires on the trail is impressive!

With respect to the 180mm ACS3 Fork Coil Conversion Kit for 2016-2018 Rock Shox Lyrik RC/RCT3, is this a new model in the pipeline?

How much travel are you looking for? Are there bikes that you have in mind that you like?

Unfortunately, we're unable to fit a coil spring into the 180mm packaging as the ratio of fork length to travel is too short. The 170mm is the max.

Trying to not come into it predisposed to particular brands and stay open minded. The typical 140-160mm. I know at my weight that finding the most coil compatible suspension design is important. I love the feel and consistency of coil shocks. My own past experiences have convinced me that not all bikes work well with coil for me. Yeti ASR 7 with RC4 felt good, V1 Bronson bottomed too easily.

I thought that the ELEVENSIX was not available for either the '17 or '18 Specialized Enduro. Is this not the case?

I have a '18 Enduro Pro 29 that I would love to put an ELEVENSIX on.
1/26/2018 4:30pm
Darren, one solution for those of us running 180mm forks would be to offer a +10mm crown race; that shouldn't be too hard/expensive to manufacturer. That would let use keep our existing geometry. Most bikes spec'd with 180mm forks run 170mm in the rear anyways.

Well, here's a list of rising rate bikes that we have a lot of success with ELEVENSIX at that rider weight:

EVIL Wreckoning
Guerrilla Gravity Smash
Intense Carbine 29
Niner Rip9
SantaCruz Hightower LT
Yeti 5.5c

You are correct. It is not available for the 2017 Enduro, and yet to be determined for the 2018 although we will be looking at that application very soon.

It, wouldn't be, but our manufacturing department is absolutely flat out machining parts and I don't think a lot of riders would necessarily give up the 10mm of travel.

Question about your Roehrig Dyno, I have an EMA 4k at work and usually run variable PVP tests up to 180 inches per second in compression and 70 IPS in tension.

just for curiosity sake and for comparison between bikes and the applications I work with, what kind of speeds are you guys seeing in your data acquisition?

whats the max peak force(ballpark) in an elevensix? again for my own selfish curiosity, for example we have a few vehicle(offload) that see rebound forces as high as 2400LBS at 70IPS

thanks for your time

A 4K is a BIG machine! I'm curious as to why you would be running PVP vs a CVP test though?

You'll see 180 IPS on compression, but 40 IPS on rebound is quite high. A lot of it really comes down to event frequency. You might see those numbers as peak events, but seeing a velocity once or twice over a series of 3,000 events doesn't really merit chasing it down if you know what I mean.

The max force depends on application, but you'll figure about 180lbs of force on bump, and 600lbs on rebound. What kind of vehicle do you have that is seeing enough corner weight to need 2400lbs of rebound damping force at 70 IPS? Those are also some big numbers!

The PVP tests came out of habit from using our old crank dyno before we got the 4K, we use the crank dyno to test each shock as it leaves the assembly line, so its nice to use the same style test while in development so we can put the curve on the crank dyno computer for the quality control guys. we do run CVP and variable CVP depending on what we are doing.

this particular tune came from a Ram 1500 truck, with a really heavy density closed cell foam bumper in the rear which as I'm sure you know has the tendency to unload quite rapidly. this peak force was done in the form of a secondary stack, call it a "heavy catch" if you will, to keep the vehicle from bucking like a mule. this is one of those events that happens once or twice maybe in a day of testing, but we found that when you really get into the heavy bump without a large amount of rebound force it can get really scary.

its really interesting to me to see the similarities between a bike and a heavy truck or jeep. 70IPS on rebound is the highest we have seen, generally more towards 50-60IPS. not that far off from what you have seen, yet the difference in spring rate and unsprung weight is huge between your application and mine.

Any reason I wouldn't be able to get an 11-6 on a '17 Bronson? I'm about 260 geared up. I just ordered a Fox 36 to replace my Pike, and I'm planning on ordering an ACS-3 Kit for that.

I've purchased 2 of the ACS3 kits, and have been really stoked with them; thanks for bringing these to market! However, I'd really like one for my 180mm 36 - which frankly is the one most deserving of coil treatment. Is anything in the works?
Oh man. I would kill for a ACS3 for 36 180mm Fox Fork.

I love my ELEVENSIX, part of the appeal to investing in it was the thought I could move the shock to my next bike... with a lot of bikes going to the trunnion, will there be a conversion option? Shock options now effect my purchasing decisionsSmile

We currently don't have stiff enough springs being offered. We currently max out at 245lb rider weight on that bike unfortunately. It is something we're looking to expand however.

Unfortunately, we're just not able to wind a spring that is stiff enough and has enough travel for the given length.

Yes, we have already done a few conversions to Trunnion for Transition Sentinel and Patrol customers. We're rapidly adding more Trunnion applications.

A bit late to the party, but anyway: More and more enduro riders are moving to coil suspension as it's better when set up properly. At the same time, more and more dh bikes are equipped with air shocks from factory and coil dh forks almost don't exist anymore (especially not with any advanced systems such as the ACS-3). Are you planning on offering any upgrades for the dh crowd? I understand there is a much larger market for enduro, and it may not be economical to make a larger 11-6 and ACS-3.
