Vorsprung Smashpot - Fork Coil Conversion System
Run over everything.
Experience phenomenal grip, control and sensitivity that you didn't know mountain bikes could even have, with the Smashpot V2- the bottomless fork coil spring conversion system for long travel MTB forks.
What's new for Smashpot V2 vs V1?
- 140-200mm travel (fork max travel permitting) vs 130-180mm
- Low-profile external hydraulic bottom out (HBO) adjustment
- Larger topout spring for silent engagement on big pulls
- Dual crown compatible - bringing coil back to downhill
- Dual-rate progressive springs for 180-200mm travels
- Wider range of external HBO adjustment
Dual-Rate Progressive Springs
New dual-rate progressive spring curves for 180-200mm travel settings give you the ultimate combination of initial compliance and deep stroke support.
Say goodbye to harshness. You've never ridden a mountain bike fork that felt this good.
Supple? Yes. Supportive? Yes.
Eat up the small stuff without compromising on the big compressions.
Smashpot V2 is more progressive at firmer spring rates - more support for heavier & harder-charging riders, without restricting travel usage for lighter & more cruisy riders.
Features:
- Phenomenal sensitivity and bump-eating performance
- Consistent, predictable spring rate in all conditions
- Cuts fork friction roughly in half compared to an air fork
- Adjustable hydraulic bottom out control for the big hits
- Caters to rider weights from 45kg (100lbs) to 125kg (275lbs) with 11 coil spring rates
- Allows lighter riders to get the most use out of their forks
- Allows heavier riders the support they need without the harshness that comes with excessive air pressures
- Easily adjust your travel with internal spacers - no new parts required
- Unique Hydraulic Bottom-out System prevents harsh bottoming
- Can be transferred between different forks with minimal parts /cost
- Reliable and low maintenance, set and forget.
- Easy to install and easily serviceable
SMOOTH & CONSISTENT
Why Coil?
Air springs have improved substantially over the years - and we've been at the forefront of air spring development for years, so we've got no bridges to sell you. 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 no moving seals in the spring system to wear out, cause friction or leak.
- Zero spring rate variation allowing more mid-stroke support and consistency.
- More oil in the fork - lubrication and service life are improved.
- In short, improvements in sensitivity, grip, compliance, mid-stroke support and consistency, with reductions in harshness and hand pain.
BOTTOM OUT RESISTANCE
Externally Adjustable Hydraulics
Low weight aside, air springs outperform coil springs in one critical area: bottoming resistance. The hydraulic bottoming control valve addresses this with a speed sensitive shimmed valve which engages progressively and seamlessly in the last 50mm of travel, bringing the fork to a smooth and controlled stop at the end of the travel. High energy and low energy inputs are effectively managed without harshness. Easy tool-free external adjustment ensures you get as much or as little bottoming resistance as you need at the turn of a dial. Increased stability as energy is dissipated, rather than stored and thrown back at you.
FAQ
How much weight does it add?
It's heavier than your air spring by between 250-450g, depending on spring rate (firmer springs are generally heavier) and the fork's original spring system. If the weight bothers you, you may be more interested in a Luftkappe or Secus.
Can I convert my fork back to air afterwards?
It depends, on some forks like Ohlins or the F38 that doesn't use the ID of the stanchion as sealing surface, then yes, possibly. There is a risk that spring rub may score the inside of your stanchion, so the the air piston may not seal again. The spring is both isolated and guided to minimise stanchion knock and rub, however we cannot guarantee an air spring will seal again after riding with a spring installed. We'd be pretty surprised if anyone actually wanted to do this after riding the Smashpot though.
Does it void the fork's warranty?
As with any aftermarket modifications, it should be expected to void the fork manufacturer's warranty.
Do I need any extra parts to change the travel?
All spacers required are included with the kit. The only thing you may want is more heat shrink for the cartridge tube, as it's installed after travel is set internally. CLICK HERE FOR SPARE PARTS.
Typical fork maximum permissible travels:
These change year by year across year models (for example, Lyriks from 2016-2022 were 180mm max, but from 2023+ they are 160mm max). Check with your fork's manufacturer regarding the maximum travel of your fork - if in doubt, don't exceed what your existing fork is currently set to.
I'm changing travel and I want to source heat shrink myself. What size do I need?
Spring:
2:1 singlewall polyolefin non-adhesive, with an initial (non-shrunk) diameter of 1.25' (32mm). 1.5' (38mm) initial diameter will also work.
Outer tube:
2:1 singlewall polyolefin non-adhesive, with an intital (non-shrunk) diameter of 3/4' (19.1mm)
INSTALLATION & MANUAL
WARNING: VORSPRUNG products should be installed and serviced by a trained bicycle service technician, in accordance with both VORSPRUNG and original manufacturers' specifications. If you have any doubt whether or not you can properly service your suspension product, or you have not performed this kind of work before, then please DO NOT attempt it. Improperly serviced products can fail, causing the rider to lose control resulting in SERIOUS INJURY OR DEATH. That's not a joke. Don't mess around with it if you don't know what you're doing, because the best case scenario is usually that you damage something in the process. Do not perform any kind of service on your suspension whilst drunk, high or stupid. We accept no responsibility nor liability for component damage or failure of any description in the case of self-installed units.

SPRING RATE ADVICE
Note:
- E-bikes - Add 15lbs / 7kg to total rider weight.
- Rockshox Zeb / Fox 38 - Riders should drop their spring rate by 5lbs/in
- 65lbs/in or higher spring rates should consider a revalve to ensure their rebound damping is adequate to cope with the spring force. Audible topout may otherwise occur.
- Cells marked in blue are where a 70lbs/in spring would ideally be used but cannot due to limited max travel
- 75lbs/in and 70lbs/in springs can be run at up to 160mm but no higher.
- 80lbs/in springs can be run at up to 150mm but no higher.
