The Capita Stairmaster Extreme is 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 an epoxy glass configuration, sintered base, and cambered construction so they're fast, strong, and have mad pop off park jumps. Combine that with a specially designed dampening system placed along the edge between the inserts, and these boards yield enhanced impact resistance as well. The performance in relation to price tag of these versatile freestyle boards is unmatched, and as a result, they're the first ones to sell out every year.
