I curious to know about de Bernardi track bikes and just want to hear from those who have ridden them. Do they have stiff BB's? Toe over lap? Are they rugged, can they handle both street and track well? Are they quick, responsive? Im looking to upgrade from the 56cm Iro Mark V(Flexes 2 much for me-I'm 190lbs) that I'm currently riding and would like any suggestions about a mid priced bike $500-800 that is worth spending the $$$ on. Thanks! My title is all ***** up, sorry.
