When I sat on the Specialized measuring pad, my sit bones measured 115 mm. According to the chart on the backside (pun intended), I should use a 143. So, are your sit bones 142mm apart?

I rode a Toupe for 4-5K miles, and it was fine. But am now back to my 130mm Fizik Arione, which is also fine ... at least once I corrected the reach. It was too much, which my fitter said can cause problems with saddle sores.
