The Madone SL 6 Gen 8 is a lightweight aero racing bike that distinguishes itself from its SLR siblings with a more affordable 500 Series OCLV Carbon, without compromising on elite racing technologies. The electronic Shimano 105 Di2 group enables lightning-fast, wireless shifting, while the durable aluminum handlebar helps keep the cost down. For an ultra-light performance, the bike rolls on sleek carbon wheels.
