avoid republic bikes like the plague. for 700 i'd get a kilo TT or an Iro and swap out the saddle, keep the extra. or you could possibly find a steamroller or something of that level. 6'1"? what is your cycling inseam (not your pants size, the actual measurement floor to crotch)? that measurement matters more than height when sizing a frame. i'd guess look at 57-58cm bikes rather than 59-61 but who knows you may have a large inseam
