The Madone SL 6 Gen 8 is a lightweight aero road bike that stands out from its SLR siblings due to its more affordable 500 Series OCLV Carbon, without compromising on elite racing technologies. The electronic Shimano 105 Di2 groupset delivers lightning-fast, wireless gear shifts, while the sturdy aluminum handlebars help keep the cost down. For an ultra-light performance, the bike rides on sleek carbon wheels.
