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 (TALAS/DPA are typically heavier than Float/Solo Air). If the weight bothers you, you may be more interested in a Luftkappe.
Can I convert my fork back to air afterwards?
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 air piston may not seal again. The spring is both isolated and guided to minimise stanchion knock and rub, however there are no guarantees 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:
Rockshox:
Lyrik/Yari 27.5'/29' - 180mm
Pike/Revelation 27.5/29' - 160mm
Fox:
36 Float/Talas 27.5' - 180mm OR 160mm - call Fox with your serial number to check max travel prior to setting Smashpot to more than 160mm travel.
36 Float/Talas 29' - 170mm OR 160mm - call Fox with your serial number to check max travel prior to setting Smashpot to more than 160mm travel.
Marzocchi:
Z1 2019+ 27.5' - 180mm
Z1 2019+ 29' - 170mm
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.
