Racing Heritage Continues On

Why We Love It
Madone SL Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point. It offers similar aero benefits to the pricier Madone SLR Gen 8, but with a more economical OCLV 500 Carbon layup and two-piece cockpit with hidden cable routing. It's built to race, with geometry that keeps you quick on the sprints yet in control on fast descents.
Upgrades
  • Shimano Dura-Ace Di2 front & rear derailleurs, crankset, and cassette.
  • Bontrager RSL Aero carbon handlebar.
  • Bontrager Aeolus RSL 37 Carbon wheelset.
Master Mechanic’s Notes
  • Light scratches on the top tube, down tube behind chainrings, & non-drive side chainstay
  • Light scratches on the crank arms
