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 comfortable on the climbs and perched for the attack. A Shimano 105 Di2 electronic groupset keeps the price down without sacrificing lightning-fast electronic shifting. Plus, it's topped off with carbon wheels for extra lightweight performance.

It's right for you if...

You want a featherweight road race bike without top-end race pricing. You're up for racing, club rides, or solo spins up winding canyons, and don't want to compromise between climbing efficiency and aerodynamics. You love the workhorse performance of Shimano's 105 groupset, but want the added benefit of Di2 lightning-fast electronic shifting.

The tech you get

An ultra-light OCLV 500 Carbon frame with aero tubing and IsoFlow comfort technology. A 2x12 Shimano 105 Di2 electronic groupset that delivers clean shifts thanks to trickle-down tech. Plus, it's topped off with Bontrager Aeolus Elite 35 carbon wheels that come set up tubeless.

The final word

Madone SL 6 Gen 8 delivers race-worth aerodynamics and climb crushing weight. It's a bonafide superbike in a more economical package, thanks to its 500-Series OCLV Carbon layup and workhorse Di2 groupset. It offers the same frame tech as its SLR sibling, like aero tube shaping and lightweight IsoFlow comfort tech, so you can stay at the front of the pack.

Why you'll love it

  1. Revolutionary Full System Foil aero tube shapes redefine what fast looks like and help optimize aerodynamics around the whole bike
  2. A more economical 500 Series OCLV Carbon frame and new tube shaping shave weight where it matters most to help you fly up climbs
  3. Carbon wheels keep weight down and performance up, so you can crush climbs and soar down descents
  4. You get lightning-fast shifts that stay crisp and clean thanks to Shimano's Di2 tech trickling down to their 105 groupset
  5. Lightweight, race-focused IsoFlow comfort tech helps you ride stronger longer without sacrificing weight or aerodynamics
  6. This bike comes set up tubeless — a first in Trek performance road history
