I thought that this forum might be the most appropriate place to ask this question:
I'm in the process of buying parts for a Lemond with a 578mm effective top tube, and 72.5 degree ST and HT angles. Assuming everything else (that can be the same) is the same, how much would reach on this frame differ from my current frame (specs listed below)?
eff. Top Tube: 580
Basically the 1 degree difference in head tube angle is what I am wondering about. I don't know if this measurement helps, but my saddle height along the seat tube, from the bb, is about 80cm.
I've spent the better part of 2 hours trying to figure this out. I'm not very mathematically inclined. If only BikeCAD Pro were free!
