The Madone SL 6 Gen 8 is a lightweight aero road bike that stands out from its SLR siblings thanks to the more affordable 500 Series OCLV Carbon, without skimping on elite racing technologies. The electronic Shimano 105 Di2 group provides lightning-fast, wireless gear shifts, while the sturdy aluminum handlebar keeps the price in check. For super lightweight performance, the bike rolls on sleek carbon wheels.
