well I’m about your height and ideally ride a 56.5cm square frame. I think. That’s the average frame size in my stable. So I guess you’d be about that. Is this for a track bike? If so that first one seems to have a slightly too short top tube and the second one slightly too long. It’s easy to get short stems but the toe overlap on a too-small track bike could be doubleplus bad.
and the fork rake and angles are much more “Track”. The seattube length, I notice, is c-t so subtract around 1.5cm for c-c distance giving a 59. My current project (road) bike is a 60cm c-c seattube and a 58cm top tube. Should still be fine. 90mm stem.
The Hoffy is a 57.5 seat and 56.5 top c-c. I’m running a 110 stem and its a little cramped.
My OZ frame (currently being built up) is a 59 seat c-c and 58 top. I’m thinking this will fit well with a 110 or 100 stem and feel comfortable, but I can let you know by Sunday Week when i’m hoping to have it on the boards!!
The road bike is a 57 top with a 120 stem.
Hope this helps a bit.
When are you planning on coming over to DISC?
And what really is normal proportions for a human?? :?
There aren’t any dealers on this side of the world. A frame that goes from Taiwan, via USA, to me hopefully. Bizarre thing is Spicer also get KHS frames of the exact geometry, just with KHS stickers. With stickers extra $50.
