Experience phenomenal grip, control and sensitivity with the Smashpot - the bottomless fork coil spring conversion system for single crown enduro forks.

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. 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.

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)
