I took my first ride on mine today. Only 21 miles, but there was quite a bit of misery involved. I am 6'5" and ~220. At first it felt great, but by mile 7-9, my sit bones got really sore and shifting the weight did not help. I will say that once I went into the drops, the pain subsided, same could be said if I repositioned myself a bit upright. Not sure if the fit (bike) is the issue, as it was my first ride on the bike, but otherwise it felt great. If my symptoms are indicative of any underlying issues (other than my Arse needing to be broken in) please chime in.
Thanks.
