Mountainbike Frame Study_02

Yes... another sketch related to mountain bike frames. Lately I have only wanted to sketch bikes, so there will be more of these. 
Fell free to comment.

As I said, I will now put more products besides cars.
Hope you enjoy this set of sketches of frames of mountain bike, using ballpoint and markers.
