Push Industries ELEVENSIX coil shock mountain bike suspension upgrade

Got your fancy new enduro bike and already pushing the limits of what it can do? Push Industries’ new ELEVENSIX coil shock could be just the ticket to boost rear end performance on a wide range of 140-165mm travel bikes.

In that travel range, most bikes are coming with air shocks, and this new model is aimed at replacing them with something that’s admittedly heavier but that provides a whole ‘nother level of performance. A sample weight for this shock for a Santa Cruz Nomad is 835g for shock and all mounting hardware. There’s really no comparison to similar coil shocks on the market because Push Industries’ Darren Murphy says these are really meant to replace something like a Monarch Debonair or Fox Float X air shock, both of which are usually under 500g.

“Bikes in this travel range are getting so light and so capable that riders are pushing them beyond what the stock air shocks can do,” Darren told us. “Our target wasn’t to compete with an air shock on weight, so they’re comparable or lighter (by as much as 100g or more) than the Double Barrel Coil or Fox RC4.”

With most stock shocks, there’s a switch that moves between firmer and softer settings, but they’re changing the settings of a single circuit, so there’s often compromise between getting one or the other (or both) fully optimized for pedaling or downhill. On the ELEVENSIX, the black switch toggles between two separate compression circuits, each of which is tuned specifically for climbing or downhill. On top of that, each circuit has both high and low speed controls, letting you really dial in the performance for a specific condition…and it’s all external, no tools needed.

Not only does it offer more control, but it’s designed to provide higher quality control over the settings. To accomplish this, they used rounded parabolic rebound and compression needles rather than the traditional pointed needles. The rebound needle’s shown as the third arrow down on the left; the compression needles are inside the two cylinders at the top and controlled by the blue knobs.

That needle shaping, according to their testing, provides a much more consistent adjustment from click to click. As they put it, you’ll no longer be wishing for a detent between clicks to find that perfect setting.

The next part of the story is the materials used. The shaft is hard coated and polished, and it slides through polyurethane double lip seals and and wipers to reduce friction. That, plus the custom high-flow damper piston, equates to rapid responses to changing terrain. The chart above shows the transition time from compression to rebound, and the lines closer together represent a quicker response. Translation: your rear wheel should stay on the ground better.

Darren says the ELEVENSIX has higher fluid volumes than the target air shocks, so there’s less fade on longer runs. And the coil spring offers much better small bump response than air shocks since there’s less initial resistance to movement. So much so that some early test riders thought they had nearly flat tires because the small bump compliance was so smooth. The coil is an exclusive HyperCo Ultra Light steel spring made of a high tensile alloy that features “Optimum Body Diameter” shaping to prevent off-center deflection and wear. It’ll be available in 25lb increment ratings to tune it to your body weight. It’s captured by a 360º ring at the bottom, as is the bottom out bumper, keeping things centered for smoother operation overall.

Lastly, it’s filled with high-end Maxima fluids. The whole thing uses domestically (U.S.) sourced parts and is assembled in Push’s Colorado facility. If you’re starting to get worried about how these premium features and parts will impact your bank account, hold your breath. The ELEVENSIX comes in at $1,200, which puts it among the more expensive upgrades you can make. If that has you waffling, their shock tuning services start at $200 and may give your current equipment a new lease on life.

Still here? Check the list of bikes it’ll fit below. But first, this parabolic needle thing had us thinking: Could that style needle be added to a stock Fox or Rockshox shock to get some of the click benefits? Or is their an air version of this shock coming, too?

“At this time, there’s no plans for (an air shock) version of this,” Darren said. “We feel like the air shock market’s pretty saturated, and we want to build products for niche customers by providing things that aren’t already available.”

As for upgrading your current shock with a parabolic needle, that’s a no-go, too. Darren says one of the benefits of building this from the ground up is that they can tune everything just right using their own designs. In order to put this needle into an existing shock, you’d have to alter or replace the shaft, knobs and other parts to make it work, at which point it becomes unfeasible.

Applications include:

  • Santa Cruz Nomad 27.5
  • Pivot Mach 6
  • Yeti SB66
  • Yeti SB6C
  • Niner WFO
  • Ibis Mojo HD
  • Banshee Rune

  • Santa Cruz Bronson
  • Intense Tracer 275
  • Ibis Mojo HD3
  • Giant Reign 275
  • Specialized Enduro 29
  • Transition Patrol
  • Knolly Chilcotin
  • Norco Range

Badass! Great idea. I think many will be willing to take the ~1/2 lb. penalty to run this… especially those who aren’t to Strava every ride 😀

I think unless you have a real specific beef with the Cane Creek coil or air options you’ll not jump. But there are some whose taste/need/requirement exceeds what the CC can do who would be willing to pay. Some people pay $700 for a damper cartridge – I don’t see why a $1200 custom shock is so outrageous.

I think it’s cool there’s an option.

I really believe that one of the major points of the Big Co’s push to air springs on all travel levels is to eliminate Spring inventory. As there is no way air springs have ever matched coils in terms of absolute plushness.

@Roy I’m sure the weight factor is a big consideration as well: not a lot of single parts on a bike that get you a ~1lb weight savings by replacing. As long as there’s a segment that will pick one bike over another based on weight savings, Air shocks will dominate the OEM market.

good point grog, for an OE bike on the floor at the local an air fork & shock are huge weight savings, but in my experience, air has never ever reached the level of supleness of coil. If I read it right this shock is nothing like a CC or anything else the way it has separate circuits, that combined with tiny production numbers and this shock price is not really shocking at all

Any idea on what the service interval would be on this? If it beat out the Can Creek (especially by a wide margin), that could be another point in its favor.

Question is does “suppleness” is a big factor ? Personnaly i found my air shock (monarch) plenty supple and as i’m also climbing with my mtb i don’t want to carry more metal. I don’t feel like your average OE buyer…

If the had one for the Banshee Spitfire I would be very interested. Seems like the perfect companion for my 36.

Awesome shock. I kind of like the air stiction for climbing but it makes good pedalling bikes work so incredibly some times. Coil & SB66 = boioioiooing

This seem to be, at the least, an all US-sourced/built Ohlins.

Also interesting to see them go with the dual compression circuits (which is rad. aka climb/descend?) vs going with a smaller shock shaft for smoother shaft action. bigger alloy shaft allows the rebound needle to be there, allowing those 2 circuits up top. This uses an IFP correct?

The two circuits is really F-in awesome.

As someone who learned to bleed shocks in a vise, it looks like kind of a biatch to bleed it due to the sideways IFP chamber. Guess you could do it in an oil bath?

I would think 2 circuits could be ‘A Line’ and Angry Pirate etc…. the ALine side would be fine for climbing as well, but on many trail networks there are some huge ranges in terrain not even talking going up. I am sure somebody in europe is working on ripping Push off already!

Sounds like an amazing shock but seriously, when did pinkbike get here?

I thought twin tube technology was better

the Cannondale and Scott pull shocks also switched between two completely separate damping circuits when you switched the mode, though not fully adjustable (rebound only). But they also changed the spring rate when you made the damping switch.

What about Avalanche coil shocks?

I like it in concept. Separate dedicated circuits for up and down.
Push needs to hack a Fox ICD servo motor on it and offer it with a Ti spring and I’m in. Next up would be forks offering a similar concept.
Pretty soon my kid will have to forego college for dads new MTB equipment “problem”.

I got a feeling air cans are going to win this one. I hope PUSH can keep up. This looks like it could be a really nice “custom” addon. Full shim and platform service for two modes…I’m in.
