Will cost around $200 / $300 if you want STI shifters. STI + handlebars + new stem + tape + mini Vs... yes pricey
But if you wanna go fast in the city fat tire road style bikes like a cyclocross bike are the way to do it. CX bikes will have shorter chainstays which = faster handling compared to a touring bike.
