The Trek Madone SLR 9 Disc with its IsoSpeed damping-system has already won our aero-bike group test. But is the all-round performance of the Madone good enough to hold up against the best race bikes of the year? Or is its range of applications rather restricted?

This bike is part of a previous group test. Here you’ll find the latest GRAN FONDO race bike group test.

Trek Madone SLR 9 Disc | 7.63 kg | € 11,499

Even when stationary the Trek Madone SLR 9 Disc looks brutally fast. Both the diagonal colour contrast and arched top tube make it jump forward visually. Both the build-quality and haptics are on the highest level – everything makes sense, from the harmonious paint transitions to the tight tolerances. Inspect how the beautifully-integrated Shimano Dura Ace Di2 R9170 groupset with compact cranks and 160 mm rotors is mounted to the Trek, and you’ll only spot a tiny section of cable just before disappearing into the calipers.

The Madone just keeps on accelerating. Unfortunately, there’s no room for a rev counter on the cockpit…

Trek developed the cockpit and seat post components specifically for the Madone. The SLR 9 rolls on 60mm Bontrager Aeolus XXX 6 carbon wheels and Bontrager R4 tan-wall tires. With a number of different bar-width and stem-length options, the two-piece cockpit offers plenty of room for personal adaptations. As part of Trek’s Project One program, customers can choose from a wide range of unique spec-options and predefined ICON paint-jobs – and if you’re really fussy you can even create your own colour scheme via Trek’s online configurator. Our test bike weighs a solid 7.63 kg in size 56 and costs € 11,499.

Adjustable comfort
The flexibility of the IsoSpeed damping system can be adapted to the weight and preferences of each rider.
All from one piece
Every little detail on the Madone has been painstakingly calculated. The precise manufacturing and tolerances are equally as impressive as the Cervélo’s S5.
Massive grip
Bontrager’s R4 tires provide consistent grip across the entire tread.
Yay and nay
The Trek comes with an integrated DuoTrap S speed- and cadence-sensor. Nevertheless, clumsy spoke magnets were uncool even before they were invented.

The Trek Madone SLR 9 Disc in test

It doesn’t matter how hard you spin the cranks of the Madone, the bottom bracket remains stiff and provides efficient acceleration. Because of the relatively high weight, the Madone lacks a certain liveliness off the mark, but still accelerates nimbly in bunch-sprints and out of corners. The Madone is an efficient climber too, provided you’re not chasing a KOM on really harsh gradients, though that’s undoubtedly due to the somewhat heavier system weight.

Once more the Madone impressed our test-crew with its good-natured, precise handling. So good in fact that it let’s you adjust your line incredibly precisely without feeling overly twitchy. The rear-end follows suit and makes the Madone feel stable at any speed while inspiring tons of confidence. This means that even at top-speed the Madone is incredibly mellow and literally begs you to hover over the white road markings – at 70 km/h! The Madone is very easy to ride and offers excellent grip.

Even when you come across tricky crosswinds it still feels predictable. It transmits an even side-pressure rather than a scary, sudden yank. Once again the adjustable and functional IsoSpeed damping system in the rear-end fully convinced us. Not only does this ingenious little piece of design dampen and defuse vibrations, but also brilliantly deals with harder knocks and bumps. Compared to the rear-end, and the cockpit comfort of some other bikes, the front-end of the Madone could offer a little more compliance.


For all aero addicts, from amateur to pro, the Trek Madone SLR 9 Disc is an incredibly fast bike with outstanding and precise handling. Over and over, the IsoSpeed system convinces us with its unique design and outstanding functionality. It was only the significantly higher weight and rather low front-end comfort that forced the Madone into second position behind our best in test.
