Hello, I ordered a 56cm Flaanimal 4.1 and when it came, I noticed it says Flaanimal 4.0 on the top tube. I think the difference between a 4.0 and a 4.1 is that the 4.1 has a 47mm bottom bracket shell? Is this frame a 4.0 or a 4.1? Are there other differences?
I love the frame and am looking forward to building a really nice commuter bike.
