Our lightest Madone SL Disc ever
New light and fast aero tube shaping paired with light-yet-economical 500 Series OCLV Carbon makes Gen 8 our lightest Madone SL Disc f/s ever and the ideal climbing bike.

Rooted in racing
Madone SL was informed by feedback from Lidl-Trek's fastest sprinters and climbers.
