The EXTREMES are limited in production and are primarily for a special customer looking for a unique product that not everyone else is going to have. They’re geared toward a progressive jib and park shredder that doesn’t want to break the bank, but is looking for more performance than the standard Stairmaster construction. They feature pre-preg glass, sintered bases, and a specially designed dampening system. This system is placed along the edge in between the inserts to enhance impact resistance on boxes and rails. The performance in relation to price tag of these boards is unmatched.
