Frame size M is in excellent condition, slightly dirty (I can’t clean it because I broke my wrist). The bike has only been ridden twice. It was disassembled and the parts were used to build a different bike.

Sour is a local German MTB brand that specializes in steel bikes. They build their front and rear triangles in batches. this frame is unique because it has a front triangle from 2024 (straight 44mm headtube) and a rear triangle from 2025 (UDH dropout, 2,6” tire clearance, post mount 180mm mount)

I’m selling the frame with a headset and crown race.
