The frame is a sturdy double butted 6061 alloy. Butting the frame means the quality of the welded area is consistent around its circumference, thus ensuring a durable frame. Butting the frame also makes the CAAD8 S 8 more comfortable to ride. Comfort is also improved from the CAAD7 with a larger number of headset stacking spacers to determine handlebar height, and the setback seatpost allows a good amount of saddle adjustment. The CAAD8 S 8 has a 8spd drivetrain and triple crankset, which will provide a good learning curve for a large variety of terrain. The combination of Shimano Sora and Tiagra are reliable and the Maddux rims with Formula spokes are durable. The CAAD8 S 8 is available in Magnesium White and Jet Black, and Charcoal Grey and Fine Silver.
