OVERVIEW

The Madone SL 7 Gen 8 is a race-ready road bike built to give you the best of every world. Its featherweight build lets you soar up climbs, while aero geometry cuts drag on descents and IsoFlow keeps you comfortable through the miles.

You want a high-end race bike that delivers on aerodynamics, comfort and a lightweight build. Carbon is important to you, but you're happy with light-yet-economical 500 Series OCLV, knowing you can save big with only a few more grams of weight. You want performance parts where they count most – like carbon wheels and an electronic Shimano Ultegra Di2 group set.

An ultra-light OCLV 500 Carbon frame with aero tubing and IsoFlow comfort technology. A 2x12 Shimano Ultegra Di2 group set for lightning-fast shifting that's completely customisable. Plus, it's topped off with Bontrager Aeolus Pro 51 carbon wheels that come set up tubeless.
