Details

In 2020 V2 introduced the Generation3 damping ferrule using a stiffer spring for increased shock absorption. Unlike the first two generations, the spring plunger in Generation3 (and the new Gen4) is field replaceable.

The plunger bolt on Generation3 is Grade 12-9, the strongest steel available for a 4mm bolt. On very abrasive pavement, the bolts occasionally wore out before the carbide ferrules needed to be replaced. We researched some thermoset polyurethanes that have exceptional abrasion resistance. As a result, we created a polyurethane cap that covers the head of the bolt on the V2 Generation4 spring loaded ferrule. Polyurethane is a good shock absorbing material, so Generation4 also has better shock damping than Generation3.
