If you desire every advantage in handling and speed and want a bike with the best technology available, the Madone SLR 9 Disc eTap is perfect for you: A top-of-the-line, 12-speed SRAM RED eTap AXS wireless electronic drivetrain, an SRAM RED AXS power metre, and Trek’s best-ever Madone frame.

An ultra-aero frame with Kammtail Virtual Foil aerodynamic tube shaping and road-smoothing manufactured of our lightest-ever 800 Series OCLV carbon Tubeless Ready Bontrager Aeolus RSL 51 carbon wheels, a micro-adjust Madone seatmast, adjustable Top Tube IsoSpeed, a KVF complete carbon fork, an aero bar and stem, a 2×12 SRAM RED eTap AXS wireless electronic drivetrain, an SRAM RED AXS power meter.

Ultralight OCLV Carbon Frame

Trek uses their ‘800 series OCLV carbon lay-up’ for the frame.

Utilizing cutting-edge technology, Trek’s 800 series OCLV carbon optimizes both the material’s aerodynamics and its properties.
On the Trek Madone SLR 7 eTap, they use this specifically created composite. Trek asserts that they employ a very high-quality carbon-resin composite because aerodynamic tube forms are heavier and less rigid than standard, spherical tubes. This results in a weight reduction of just under 10% when compared to an OCLV 700 frame, with the SLR frame manufactured from OCLV 800 weighing in at just 698 g. The lighter the material, the higher the number after the OCLV.

Less material needs to be used to produce the same riding qualities thanks to the new material’s astonishing 30% increase in strength over prior OCLV Carbon while maintaining the same stiffness.

Geometry and Comfort

Madone has a few modifications to make the riding more comfortable. Its geometry is given a Goldilocks-style makeover. It is known as H1.5 and it lies halfway between the rigid H2 endurance geometry and the aggressive H1 geometry. It’s a balance that puts you in a position that is unquestionably more aerodynamic, but one that we could easily ride for hours in. The Madone’s next comfort feature is adjustable top tube IsoSpeed, a design idea that was first created for the Domane spring classics race bike.

Hydraulic Disc Brakes

The hydraulic disc brakes are quite good; they modulate more easily and with a softer initial grasp than Shimano calipers. And points to Trek for specifying 160 mm rotors front and rear in addition to the basic dual-sided power meter, given the greater speeds riders are expected to hit on this thing.

Color Choices

For Men & Women: 

Madone SLR 7 eTap is available in Six colors—Dark Prismatic/Trek Black, Navy Carbon Smoke/Viper Red, Navy Carbon Smoke/Blue, Matte Deep Smoke, Amethyst, Radioactive Coral to Yellow Fade. Also variety of Eight sizes (47, 50, 52, 54, 56, 58, 60, 62). It weighs roughly (size 56) – 8.20 kg / 18.08 lbs. This bike has a maximum total weight limit (combined weight of bicycle, rider, and cargo) of 275 pounds (125 kg).

Oh! What a feeling

Madone is faster on any surface and in any situation thanks to our 800 Series OCLV Carbon laminate, which is the lightest laminate we’ve ever produced.

includes an SRAM Force AXS power metre for earlier, more productive training rides.

Top Tube Adjustable With the ability to customise compliance to your preferences, IsoSpeed rebounds in a regulated, smooth manner and is damped with an elastomer.

You can have excellent adjustability with a separate bar and stem that has an aero carbon faceplate.

The ultimate race bike is truly a work of art thanks to the Madone Project One ICON paint schemes.

What does eTap mean on trek?

The first totally wireless electronic shifting technology and the brain of SRAM’s RED eTap road group is known as the electronic drivetrain for bicycles known as “eTap.” Airea, a totally wireless protocol developed by SRAM, is used to send and receive shift signals.

The Madone accelerates and maintains speed unlike any other vehicle I’ve ever driven. With prolonged stretches of 45+ km/h, our group rides average 34 km/h or better.

What does SLR mean in bikes?

SHIMANO Linear Response is referred to as SLR. The caliper, lever, and cable of the NEW SUPER SLR design all incorporate friction-reducing mechanisms to enhance response and modulation.

Our Rating​

The pinnacle of Madone. You receive a 12-speed SRAM RED eTap AXS electronic drivetrain, a power metre, and the most advanced aero carbon frame we’ve ever produced. You may customise any setting with the AXS app, and it has developed to be smoother and more straightforward.

Comfort is one area that aero bikes have made huge strides in in recent years, and the Madone is no exception. It’s easily rideable all day.
