I’ve been riding a fixed gear bike this season. It’s so flat here, the only reason you need gears is to deal with the wind. This is my Bianchi Pista, with some mods. 1) Nitto Stem and Moustache handlebars. 2) Switched out the black seatpost for a shiny aluminum one. 3) Sugino RD cranks. 4) MKS pedals. 5) Fizik Pave seat I found in the used bin at a local bike store. 6) Nice, thick Japanese cloth handlebar tape finished off with whipping cord. 7) Schwalbe Marathon “Slicks” (700 x 30). Very smooth-riding, but nearly bullet-proof tires.
