PRESS RELEASE: Vorsprung SuspensionRun over everything.When you just want the best bump-eating suspension quality possible no matter what, there still isn't a match for the age-old coil spring. And we'd know - we've been at the forefront of air spring development for years, pushing air spring performance closer to that of coils.
We present to you the
Smashpot - a fork coil spring conversion system for singlecrown enduro forks, featuring externally adjustable hydraulic anti-bottoming technology to deliver precisely the amount of bottoming resistance you need.
Why Coil?Air springs have gotten better and better over the years, and they've been around for so long now that some people have never ridden a coil spring. Yeah, coils are heavier than air, and for some riders that alone is a dealbreaker - fair enough. The advantages of coil springs, however, are clear:
• Zero stiction or friction in a coil spring. And there never will be.
• Zero spring rate variation - linear, predictable, supple, supportive and consistent.
• Zero moving seals in the spring system to wear out or leak.
• Zero effect on spring rate from temperature or elevation.
• More bath oil - lubrication and service life are improved.
• Day in, day out, the fork just straight up feels good.
In short, improvements in sensitivity, grip, compliance, mid-stroke support and consistency, with reductions in harshness and hand pain.
Weight aside, air springs outperform coil springs in one critical way: bottoming resistance.
Enter the Smashpot.
Externally adjustable, speed sensitive, hydraulic bottoming control valveAt the heart of the Smashpot is a hydraulic anti-bottoming system that engages seamlessly and progressively over the last 50mm of travel, utilising a speed sensitive shimmed valve to effectively manage high energy and low energy inputs without harshness. Easy tool-free external adjustment ensures you get precisely what you need.
Why go this route?Unlike conventional hydraulic anti-bottoming cones, the longer displacement over which it is effective and its speed-sensitive shimmed valve means the Smashpot can dissipate more energy at lower forces, bringing the fork to a gentle stop at the end of the travel in a smooth, controlled manner.
Compared to alternatives such as elastomer or pneumatic bump stops, the Smashpot doesn't involve components physically colliding mid-travel. Unlike air springs and pneumatic bump stops, it dissipates kinetic energy rather than storing it and throwing it back at you, further stabilising the bike. There's no spring stiction, fewer wearing seals, fewer seals to fail, and no need for a shock pump -
ever.
Smashpot Features:• Compatible with Fox 36 and Rockshox Pike/Lyrik/Yari/Revelation (35mm) forks. Other fitments under development.
• 130-180mm travel, internally set using included spacers.
• Full tool-free control over bottoming resistance.
• 11 coil spring rates available, from 30lbs/in to 80lbs/in precision wound in 5lbs/in increments.
• Rider weights from 45kg (100lbs) to 125kg (275lbs) catered for.
• Universal cartridge kits require only new top caps to be moved between different forks (and foot studs if different fork brands).
• Springs are guided and isolated both internally and externally to reduce spring buckling, minimising noise.
• Spring guiding system also means less rubbing, less wear and less contamination of the bath oil.
• More bath oil for improved lubrication and smoothness.
• Cheaper and more adjustable than comparable competing coil conversion kits.
• Only coil conversion on the market allowing 180mm travel.
• Easy and cost-effective to transfer from one fork to another.
• Allows full use of travel even for light, smooth riders.
• Prevents harsh bottoming.
• Reliable and low maintenance.
• User installable.
• Designed, developed and manufactured in Whistler, Canada.
• Weight increase of between 250-450g (dependent on spring rate and fork).
• MSRP
$420.69CAD (approximately $315USD) • Kit includes universal Smashpot cartridge, fork-specific topcap and one spring.
• Replacement springs MSRP $80CAD (approximately $60USD)
What are the downsides of the Smashpot?• It adds between 250-450g to your fork, depending on spring rate and the type of air spring previously in your fork. If this bothers you, you may be more interested in a Luftkappe.
• Going back to air, should you wish to, may not be an option - spring rub may score the inside of your stanchion, so the the piston may not seal again. We doubt you'll want to after riding the Smashpot though!
• Changing spring rates requires physically changing a spring, not just connecting your shock pump.
• As with any aftermarket modifications, it should be expected to void the fork manufacturer's warranty.
• We recommend riders requiring spring rates of 65lbs/in or higher also consider a damper revalve - stock dampers lack adequate rebound control for these spring rates.
Our engineering and design are straightforward and no-BS, so we think our marketing should be too: if your first priority for your fork is outright performance, get yourself a Smashpot.
Available now directly from
Vorsprung or your local dealer.
MENTIONS: @VorsprungSuspension
For what it's worth, we have more air spring stuff in the works, we certainly aren't abandoning it.
My point I know a lot of motorcycles come with progressive coil springs by design, and if this has been explored for MTB springs.
We looked at it when designing the Smashpot, it just wasn't worthwhile for this application - hard to get substantial additional force without more weight and/or higher risk of spring failure, plus it lacks the adjustability. Snowmobile shocks for example usually use progressive springs and they have by far the highest rate of spring failure of any vehicle suspension I've ever seen.
COOL, anything for xfusion Metric??
Does that still hold true or has manufacturing improved so much that this is no longer a concern?
That way fence sitters could go back to air for selling or other purposes
@VorsprungSuspension - no comment about working on these for the E BIke CSU 36 Series forks from Fox?
Changing from a Lyrik to a 36 or vice versa requires a new foot stud assembly and a new top cap. Top caps are $30CAD, foot stud assemblies will be somewhere around $80 but pricing has not yet been finalised on those as we don't yet have them available separately.
So fast forward 6 months of Pike love and Rockshox teased me with a 19 Lyrik. Debonair, super supple new super dooper damper. Biggest mistake ever. Maybe I had a bad Lyrik but the damper was awful. It's so bad I sent it back as a warranty claim. 3 rides in the seals weren't sticky any more but the damper was way over damped on the compression stroke. LSC and HSC fully backed off, sore wrists and front wheel washing out. Bag of poop.
Also, we're a small company and the marketing is what the engineering department does in their spare time. Better than the other way around though
“Also, we're a small company and the marketing is what the engineering department does in their spare time. Better than the other way around though”
That’s the best line I’ve read in ages, think I might print that one out and present it at our next, marketing and engineering meeting !!
The ribbon is very good, the acs3 is fantastic, this should be awesome too. There is nothing like tha lt first ride with coil on your bike after ditching air. ... regarding the hydraulic bottom out, its very clever, I first saw this on the ext storia. I guess this is very common in motorsports.
I understand the theoretical "disadvantages" of the pneumatic bumpstop (push) but this also engages at the end of the travel at very high speed events, the coil force pushing back is high enough to make that little air spring force not that "unstabilizing"....?
"No thanks, I'll pay MSRP"
"...Alright, that'll be 420.69"
"heheheheheheh"
LOL.
Cudos though, this will probably be part of my next bike.
250# of thanks.
It runs on the splash lube. There's a shimmed valve and adjustable orifice in there to control flow, plus a couple of other flow paths to taper the effect in gently.
However, the Smashpot is cheaper, has internally adjustable travel, goes to both longer AND shorter travel settings, has a wider range of spring rates available, is transferable between forks at a minimum of cost, has no components impacting one another mid travel, has no air seals to worry about, doesn't need a shock pump to adjust and is guaranteed* to get you laid.
*eventually, probably.

*eventually, probably.
you got me
Value for money - the Luftkappe is extremely hard to beat, it's relatively cheap, weighs next to nothing and it makes a substantial difference. Outright suspension performance - the Smashpot wins.
Can I pre-order?
But if the fork is different, you'll probably need a new CSU for the old bike. Cheaper just to leave the Smashpot in the old fork and buy a new one - $300 USD for a CSU + labour to install, Vs $315 for the new Smashpot...
Or - maybe the coil spring has not scratched the inner of the stanchion badly enough to affect the air seal. I don't know of any reports of how long it takes, or what sort of damage occurs. Maybe people who go coil aren't flipping their bikes yearly?
And exactly what @nouseforaname said.
Silly me.
Must be fun being the cool guy at the party. Thanks for fantastic mods
Truth be told I love the 2019+ fox forks and wouldnt change it.
Spring rate will need to be 65lbs. What is this damper Revalve that is mentioned and should I consider this?
You mention revalving the damper. I would need the 65lb spring.
What does this involve?
"Ramp Control in the Ribbon Coil works by controlling the flow of ambient air found in the lower leg into the
stanchion. Air transits freeley on low and moderate speed compressions regardless of Ramp Control knob position, but during high-speed compressions, when set firmly, transit is impeded - providing a boost to the
spring rate."
is this a common thing with the ribbon? i've been thinking about picking one up but bushing problems are my least favorite defect to deal with since they are so difficult to fix on your own
On the trail I don't think I noticed any problems except it muted the trail a bit too much for my liking. I think my preference is to have more ramp up towards the last 1/3rd of the stroke. The MRP has ramp up at the last 1/6 of the stroke so pumping and stuff was not as responsive as an air shock or ACS3/Smashpot
Guessing it will be available through tftuned in the UK?

Casem se snad objevi i pruzina☺Ale musim rict, ze Luftkappe je super a opravdu snizuje neskutecne odtrh!
Any problems so far with the kit ? I was gonna buy a push kit but I've read too many posts about disintegrating o-rings and weird metal noise while riding. Hopefully yours will be better
I've seen reports of noises, but all seem to be traced back to spring hitting the inside of the fork (cured with some grease and shrink wrap) or the bump stop plunger knocking, but again that was resolved with a new rubber bumper (as per PB reviews) - I hadn't read about o rings disintegrating?
