These are the K2 r100 Frames. They run around $99 US. They’re machined out of extruded aluminum which makes them extremely solid. They’re UFS and are designed to fit four 100mm wheels.

These are the Kizer Arrow frames. They’ll run you around $90 US. They’re UFS and fit up to an 80mm wheel. This means they’re perfect for aggressive skaters interested in trying big wheel blading.

These are the Ground Control TriSkate frames. They're UFS and come complete with 110mm wheels and ABEC 9 bearings for $140 US. You can also get them with 125mm wheels, or with just the frames. They've been optimized to ride with the Razors Cosmo skate, or with the Cosmo soul plates on the Razors Shifts. 

I haven't been this excited about a new skate product in years. The Oysi (aka Oysius) frames feature a wide split, built in rocker and a groove to prevent wheel bite. They're a dream come true, or are they? I tried them out in the neighborhood then took them to the Durham skate park to see how they hold up.

These are the Go Project Crown Bearings. They'll run you around $80 for a set of 16. These bearings are, different. Instead of the normal one piece design you're used these bearings have this little copper crown that slides in the middle.
