New frame!

Today I got a new frame, Cube Stereo 160 C:68 27.5 action team 20″.

Here is some porn.

Converted to hardtail via 20mm electricity tube. (to prevent the swing from hitting the frame)

The scales were tipped at 2259g for the frame with internal routing guides and some screws.

Wheel clearance is quite good, chainstay measures from 75 to 80mm in the tire area.

Unfortunately the Pike is not quite the same color ;P

The downtube seemed like black in the retail pictures, but it is not 🙂

what is this? why? science??

I started searching for information and soon discovered that there were multiple cooks in the mix and that oval chainrings could be the next thing in mountainbiking …or maybe just another gimmic?
