I know someone else just posted a thread about frame design, but mine is more specific.
Keen on putting together a bike that actually fits. The smallest 700c bikes have issues with toe overlap, and tend to be slackened at the front in an attempt to reduce this, which to me seems to fuck up the handling. Or at least perceived fun. So looking at 650c front. A bit like this;
My current road bike is as follows, want to base everything off this as the geometry aside from the fact it is a little long. Really makes me whooosh. So want the same angles. Would not dispute having BB even higher, high BB's are very agreeable for me. Low ones for some reason make bikes feel super sluggish for me.
The top tube on this is 54cm and I would like it to be 51.5 without changing headtube or other angles. (the seattube is 52) I ride this bike with bullhorns currently, because my arms are in no way long enough to hold the drops. The lowness is not an issue, it is how "forward" they are. I do want to use drops though. Even with the bullhorns it is a bit of a stretch.
I was hoping to get it done by mielec for cheapness, a bit of an experiment. With a gear hanger if they are able otherwise a fixed.
Anyone mind giving me some pointers on how to go about this? Do I need to find a fork before planning the geo? Do I need to bother accurately measuring angles of my existing frame?
