After 1,000 miles on the bike I finally dialed it in. The bike is very stiff at the BB area. Compared to BB30 and BB90 and it is as stiff as the Fuji SST 1, a bit stiffer than the Willier cento 1, and felt stiffer than the SL3 Specialized. So I am happy about the $3,699 I spent on this bike. (I did spend a bit extra $195 speed play pedals, $150 FSA K Force stem).
