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.
How do I specify the travel I want?
Travel is set internally during installation, anywhere from 140mm to 200mm (don't exceed the maximum your fork is able to use!). You don't need to specify a travel when you order - your kit can do any of those.
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. If you do not have the original parts, you may also need 'Travel Adjust Kit'. You will want 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 - Smashpot V2
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.

Equivalent spring rates for dual-rate springs
Note that this is ONLY relevant for 180-200mm settings.
140-170mm only use one spring, and have a linear spring rate.
The Primary spring is the one you'll need to actually order. It's what determines the stiffer part of the dual rate progressive spring rate.
The lower value (eg the 38 in 38-55) is the starting spring rate, and the average is the average of the two at 200mm travel.
30lbs/in Primary: 24-30 lbs/in (26lbs/in average)
35lbs/in Primary: 27-35 lbs/in (31lbs/in average)
40lbs/in Primary: 30-40 lbs/in (35lbs/in average)
45lbs/in Primary: 33-45 lbs/in (39lbs/in average)
50lbs/in Primary: 35-50 lbs/in (44lbs/in average)
55lbs/in Primary: 38-55 lbs/in (48lbs/in average)
60lbs/in Primary: 40-60 lbs/in (53lbs/in average)
65lbs/in Primary: 42-65 lbs/in (57lbs/in average)
70lbs/in Primary: 45-70 lbs/in (61lbs/in average)
