Aero road. Those two words carry plenty of weight these days. A sleek bike that practically encourages solo breakaways. Other aero road bikes have been saddled with a punishing ride quality and pudgy numbers on the scale. But not the Madone SLR Disc.
Trek took a close look at the previous-gen Madone 9-series and looked at what worked and what could be improved upon. The new Madone SLR bikes are all constructed of Trek's premiere 800 Series OCLV carbon fiber, allowing the engineers free reign when designing in aerodynamics, lightness and torsional strength. The overall shape of the current (and previous) Madone road bicycles comes from a demanding field in aerodynamic design: Le Mans sportscars. When long-tail racing cars proved to be unstable in crosswinds, designeers lopped off some of the tapered rear end of the cars. They discovered that the change had almost no effect on top speed, but helped to keep overall weight down as well as improve control in gusty crosswinds. Cool, huh? At speed, the airflow rejoins behind the car as if the bodywork was still there. Called Kammtail Virtual Foil (or KVF), the Madone's shape takes full advantage, making the bike a much lighter and more controllable machine.
From top to bottom, the Madone SLR takes well-thought details and produces a super-clean bike that shows almost nothing to the wind. By submerging all the cables and hoses inside the multi-piece handlebar, stem, frame and fork, the Madone SLR's drag number stay very low. An aperture in the left chainstay for a DuoTrap S speed/cadence sensor eliminates the need for clumsy zip-ties. Even the adjustable 3S chain keeper got an aero makeover. Tires up to 28mm can be fitted, allowing the bike to get even more comfortable over rough and choppy pavement.
All this might sound like the kind of stuff Trek's competitors would do when trying to build a copy of the Madone SLR. But there's one thing they can't build into their bikes: adjustable IsoSpeed. The previous generation Madone SLR took the world by storm with an IsoSpeed rear seat mast, making it more comfortable than plenty of road bikes in general, not just other aero road machines. With this Madone's adjustable IsoSpeed component found under the top tube, the bike can adjusted for different rider weights, different road surfaces and expected ride quality in general. Like the Domane SLR, two allen wrenches are all that's needed to do a roadside adjustment in seconds. The IsoSpeed unit also features a reduced rebound by 13%, keeping the bike from feeling "bouncy" over repeated impacts. A fresher rider will race the last mile of any event better than a tired rider. IsoSpeed just makes sense for everyone.
SRAM Rival eTap AXS components are a brilliant pairing to the cutting edge technology found on the Madone SLR frameset. The drivetrain is completely wireless, and shifts are literally lightning quick. The eTap AXS batteries are rechargeable, with a single charge lasting for about 500 miles, depending on usage. The wireless drivetrain can be used with a smartphone app to determine battery charge levels and customize shifting. A 48/35T alloy SRAM Rival crankset works in tandem with a SRAM XG-1250 10-36T cassette, bringing a very wide gearing range to the Madone SLR 6. Trek made sure the Madone SLR 6 was a capable bike in the hills, not just the flats. The SRAM Rival crankset is equipped with a spindle-based Quarq power meter, allowing the rider to ride, train and race with a better understanding of their overall fitness.
Bontrager supplies the Aeolus Pro 51 wheelset, slicing even more drag off the Madone SLR 6. A 51mm carbon fiber rim with a Dual Directional Design (or 3D, for short) profile is not only fast, but resists crosswinds better than conventional wheels. A 23mm rim internal width allows tires to corner better. The wheels are tubeless-ready, allowing a wider range of tire choices. Alloy DT Swiss 350 centerlock hubs are smooth, reliable and boast 18-point positive engagement. Bontrager's 700x25c R3 Hard-Case Lite tires corner and sprint with the best. SRAM's Rival flat-mount hydraulic disc brakes boast excellent stopping power in all conditions, rain or shine.
The Madone SLR 6's peripheral components haven't been forgotten. Bontrager's Aeolus Elite saddle is designed to be comfortable when the rider is in a more aggressive, aerodynamic position. The blade-style OCLV carbon fiber Madone road handlebar and Madone stem offer a wider range of adjustability than a one-piece bar-and-stem combo unit.
A SRAM battery charger is included with the purchase of this bicycle.
