Smashpot Coil Conversion

Run over everything.

Presenting the Vorsprung Smashpot - a fork coil spring conversion system for single crown enduro forks, featuring externally adjustable hydraulic anti-bottoming technology to deliver precisely the amount of bottoming resistance you need.  The benefits of coil are clear: if your first priority for your fork is outright performance and grip, get yourself a Smashpot.

Vorsprung SmashpotFeatures:

•   Catering to rider weights from 45 kg to 125 kg with 11 coil spring rates

•   Allows lighter riders to get the most use out of their forks, and heavier riders the support they need without excessive air pressures

•   Only coil conversion system on the market allowing 180 mm travel (note that 190 mm is not possible with the Zeb)

•   Easily adjust your travel with internal spacers (note the minimum & maximum travel of your fork as determined by manufacturer)

•   Unique Hydraulic Bottom-out System reduces harshness

•   Can be transferred between different forks with minimal parts cost (a purchase of a new top cap or foot stud)

•   Reliable and low maintenance, set and forget.  User installable and serviceable

•   Weight increase of approximately 250-450 g (dependent on spring rate and fork's existing spring system)



Why Coil?

Smooth & Consistent

Vorsprung SmashpotLow 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 50 mm 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.
