Then and Now! 25 year's!

The original 1985 Allez from the movie American Flyers. The frame was constructed using Tange Prestige tubing and featured lugged construction

The Tarmac SL3 uses Specialized’s FACT IS (integrated Structure) carbon manufacturing process. The frame is comprised of four main parts: The front triangle, seat tube, seatstays and bottom bracket/chainstays assembly. To increase the stiffness of the rear triangle the oversized bottom bracket and chainstays are one piece. The bottom bracket shell also does away with metal bearing cups to save weight and features internal carbon ribs that stiffen the juncture between the bottom bracket bearings and the frame. Specialized uses hollow box section alloy dropouts to increase stiffness in the rear triangle.
