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.
• 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)
Smooth & Consistent
Air springs have improved substantially over the years. 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
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 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.
