Aero Speed Meets Everyday Performance

The 2026 Madone SL 5 Gen 8 is Trek’s most accessible aero road race bike yet, blending top-tier performance with unbeatable value. Drawing inspiration from the flagship SLR models, the SL 5 brings the same race-winning Full System Foil aero shaping and IsoFlow seat tube tech to a more attainable package, using a 500 Series OCLV Carbon lay-up and a smart two-piece alloy cockpit with hidden cable routing.

Engineered for speed, comfort, and efficiency, this Gen 8 Madone comes equipped with a smooth-shifting 12-speed Shimano 105 groupset, lightweight Bontrager Paradigm wheels, and fast-rolling 700x28mm Bontrager R3 tyres. Its race-tuned geometry, integrated aero seatpost, and carbon fork offer responsive handling and a planted ride feel, whether you’re chasing personal bests or leading the bunch. The SL 5 is built to perform but sensibly spec’d to keep the price in check.

Highlights

  • Lightweight 500 Series OCLV Carbon frame with aerodynamic Full System Foil shaping

  • IsoFlow seat tube increases comfort and improves aerodynamics

  • Shimano 105 R7100 12-speed mechanical drivetrain for precise, reliable shifting

  • Bontrager alloy wheels and tubeless-ready 28mm tyres for speed and grip

  • Internal cable routing with a sleek RCS cockpit and aero seatpost design

  • Madone Gen 8 full carbon fork for added control and weight savings

  • Clearance for up to 32mm tyres for versatile road conditions

The Trek Madone SL 5 Gen 8 2026 is the perfect race-ready aero road bike for riders seeking Tour-level tech without the premium price tag.
