The geometry for the new Pinarello F4:13 published on the competitivecyclist website doesn't make sense. It claims that a 57cm (c-to-c) has a 72.5 degree seattube angle and 18.5 cm of setback. Something's wrong because that trig doesn't work. The Gita website has a geometry chart in Italian and it appeards the head tube length is 18.5m not the setback. Perhaps competitivecyclist.com reversed the head tube length and setback numbers. Even still, the 17.9 cm is right either assuming it's a true 57cm center to center. What gives?
