As I probably mentioned before, Pinigin is a Local trials-welder (Trials Rider before), who is known among Russian Riders. This is his first 24 frame, and he tried to make it strong and light, adding some design to it. Another Important note is that frames made by him are mindblowing strong. You will probably blame this headset design, but none of 40 frames with this headset were broken. weight - 1800 SOme pics:
