First let me talk about some of the Tri Bike characteristics:
A lightweight frame made of aluminum, aluminum plus carbon fiber in the seat stays, or all carbon fiber. And a hard, narrow seat that is positioned higher than the handlebars. A seat that is angled 76 to 78 degrees. A short top tube upfront that allows the rider to comfortably lean forward onto aero bars. A big and little chain ring in the front, and nine or ten in the rear for max speed. The wheel is made of carbon tri spoke wheels, can reduce wind resistance compared with most road bike. Narrow tires that are pumped to high pressures.
