The FX 2 has been a fan-favorite for a few seasons, which might make Trek averse to changing such a popular bike. But you'd be wrong...

The best change to be found is the bike's frame, with an upgrade to Trek's Alpha Gold aluminum tubing. Tapered and flowing tube shapes give the FX 2 a stunning look as well as lighter weight and greater strength. The FX 2 boasts mounts for a rear rack, fenders and water bottle cages, adding versatility for commuting duty. Internal cable routing keeps the shifter cables cleaner for longer, as well as adding to the bike's sleek lines. The FX 2's overall fit and size range works with a wide range of riders and rider flexibilties, too. Keeping track of your rides on your smartphone? There's even an aperture in the left chainstay for a DuoTrap S ANT+/Bluetooth speed/cadence sensor (sold separately).

A bike is only as good as the components chosen for it, and Trek knew that wheels make all the difference. Bontrager's 32-spoke Connection alloy wheels are shod with semi-treaded Bontrager H2 Comp 700x35c tires, adding easy acceleration and confident grip on pavement and hardpan trails. Plan on riding on hilly countryside roads? The FX 2 features a 48/38/28T triple crankset and 11-32T Shimano rear cassette, offering a massive gearing range for heavy loads and steep ascents. Gear changes are done with 8-speed Shimano shifters and derailleurs, bringing fingertip operation to the party. Tektro HD-R280 hydraulic disc brakes help keep speed reigned in, no matter the conditions, rain or shine. An accessory-ready alloy Blendr stem adds a spot for a phone or headlight mount. Bontrager also provides the alloy seatpost, Sport saddle, alloy handlebar and comfy long-tail Satellite grips to complete this excellent machine.

This bicycle was produced by hand in Waterloo, WI, using the same molds and techniques as the Madone 6.9 SSL of the same year. The bicycle uses Trek's proprietary OCLV 110 carbon fiber material for very light weight and impressive torsional strength. An aggressive geometry provides nimble handling and lightning-fast pedaling response, especially during uphill, out-of-the-saddle efforts. Up front, a 1-1/8" Cane Creek external-cup headset holds the lightweight Bontrager Race X Lite OCLV 110 carbon fiber fork. The Madone's cables are all externally routed, allowing easy servicing in the field.

The Livestrong Madone bicycles feature real gold leaf panels on the top tube, down tube and seat tube. Lance Armstrong's signature appears across the top tube under the clearcoat. Yellow highlights and custom graphics adorn the bike and many of the components.

Shimano's 10-speed 7800 Dura Ace components are found throughout the bike, including the dual-control levers, both derailleurs, both multi-pivot brake calipers, and the 12-25T cassette. Long service life and precise operation can be expected for years to come from Shimano's best pro-level components. A Bontrager crankset with carbon fiber arms, 53/39T chainrings and matching custom graphics is an impressive centerpiece to the Livestrong Madone. Bontrager Race X Lite alloy wheels also feature custom yellow spokes and carbon fiber hubs, and are wrapped with 700x23mm Bontrager tires. A Bontrager carbon fiber seatpost, Bontrager saddle, Race XXX Lite carbon fiber stem and OCLV carbon fiber handlebar also boast custom yellow graphics.

The current generation Madone has set a very high standard for aero road bikes. Now all that performance can be had for less...

Trek's current Madone has helped pro racers win some of the most prestigious victories in professional racing, including the 2019 world road championships in Yorkshire. Attaining that technological masterpiece is not quite as expensive as it used to be. Welcome to the Madone SL 6 Disc.

The Madone has been acclaimed as a brilliant aero bike, with very low drag to cheat the wind. The original Madone SLR Disc also boasts incredibly good ride quality -not just for an aero bike, but for road bikes in general- due to an adjustable IsoSpeed seat mast. This clever element of the Madone SLR's frame is also found on the more budget-friendly Madone SL. By moving a slider on the base of the L-shaped IsoSpeed structure under the top tube forward or backward, the seatmast can be made stiffer or softer. Different rider weights, expected riding surfaces or ride distances can all be accommodated with this feature. Triathletes will appreciate this, knowing that a smoother ride quality will benefit them during the run. Century riders will also smile, knowing the bike will be more comfortable on broken tarmac. Racers will like IsoSpeed since the freshest rider is most likely the fastest in the final sprint to the finish.

Very light weight is still part of the Madone SL's attributes, thanks to Trek's exclusive 500 Series OCLV carbon fiber used throughout the frame. By using newer flat-mount disc brake installation and an H1.5 fit geometry, the frame of the Madone SL 6 Disc cuts weight in the right places. Like the current Madone SLR, Kammtail Virtual Foil (or KVF) tube shaping is used throughout the Madone SL's frame and fork, making the bike one of the slipperiest road bicycles today. The flattened trailing edge of the frame and fork tubes (the "Kammtails") make the bike far more resistant to gusty crosswinds compared to a classic teardrop shape, as well as cutting weight off the bike. An aperture in the left chainstay for a DuoTrap S speed/cadence sensor (sold separately) cuts aero drag by eliminated the need for clumsy zip-ties. Even the 3S chain keeper at the crankset has been given the low-drag treatment. A stout BB90 bottom bracket anchors the crankset for flex-free power delivery with every pedal stroke.

The Domane SL 6 Disc uses Shimano's R8000 version of their venerable 11-speed Ultegra component group. This ensures precision functionality, long service life and light weight. Here are a few of the highlights:

• Redesigned dual-control levers and lever hoods that feature adjustable lever reach and a more comfortable textured grip
• A Shadow-style rear derailleur that improves shift quality and takes up to a 30T rear cog
• A Toggle-pivot front derailleur that requires less hand strength to shift to the large chainring
• A 50/34T compact crankset with a more flattened profile for better aerodynamics as well as stiffness for better power transfer
• Hydraulic disc brakes with improved heat dispersion and 160mm rotors for improved stopping power

An 11-30T Ultegra cassette and Ultegra chain add a wide gearing range for challenging courses, as well as precision shifting and low drivetrain friction.

Bontrager supplies the tubeless-ready Aeolus Comp 5 Disc wheelset and 700x25c R3 Hard-Case Lite tires, adding an extra aerodynamic weapon to the Madone SL 6's arsenal. A 50mm deep rim with a bullet-nosed profile not only slices the air in a wider range of wind angles, it handles better in gusty crosswinds. Shimano Ultegra hydraulic flat-mount disc brakes boast excellent stopping power in all conditions, rain or shine. The Madone SL 6's Bontrager Aeolus Comp saddle is a new design that enhances comfort for riders in an aggressive aero position. A conventional alloy Bontrager Pro Blendr stem and alloy Elite Aero VR-CF road handlebar accept clip-on aero bars for triathletes seeking a better bike for technical courses.

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.

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, only 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.

An ultra-rigid BB90 press-fit bottom bracket is an excellent anchor point for any installed crankset, ensuring no power is wasted under hard efforts. Cleanly integrated brake calipers help keep drag to a minimum.
