Summary

The Trek Madone is a highly aerodynamic road bike praised for its exceptional speed and race-focused performance. It features innovative technologies like IsoSpeed or IsoFlow for improved comfort and handling, though some models may have a firmer ride. While it excels in efficiency and stability, it often comes with a high price and can be heavy compared to non-aero bikes.

Pros
  • Excellent aerodynamics and speed

  • Comfortable ride with adjustable suspension features

  • Precise and stable handling

  • High-quality build and integration

  • Competitive weight for an aero bike

Cons
  • High price range

  • Heavy weight affecting climbing

  • Firm ride on rough surfaces

  • Susceptibility to crosswinds

  • Limited comfort in some models

Highs
  • Superb aerodynamics, comfy ride, excellent handling, accommodating cockpit design, threaded bottom bracket.

Lows
  • So-so front-end ride, so heavy.

Trek Madone SLR gets lighter with new carbon fiber, also adds T47 bottom bracket

Jul 2020 · Zach Overholt

What’s better than Trek’s Madone SLR? How about a Madone SLR that’s lighter? Or one with a different bottom bracket?

Trek Madone SLR 9 Disc review

Apr 2019 · Benjamin Topf

The Trek Madone SLR 9 Disc with its IsoSpeed has already won our aero-bike group test. But is the all-round performance of the Madone good enough?

Highs
  • Integration

  • Rear-end comfort with adjustable IsoSpeed damping

  • High-speed performance

Lows
  • Front-end could provide more comfort

  • Compact cranks only work up to 50 km/h 😉
