Trek’s answer to tackling rougher terrain comes in the form of IsoSpeed; a decoupler that allows the seatmast to move independently from the rest of the bike, increasing comfort yet still keeping everything as efficient as possible. The Trek Domane SL 8 Road Bike 2017 features this innovative solution, and when twinned with a 500 Series OCLV Carbon frame, fork and Shimano Dura-Ace 9100 componentry, this bike becomes ready for anything.
Trek Domane SL 8 Road Bike 2017
Trek Domane SL 8 Road Bike 2017
Trek have pulled out all the stops with the Trek Domane SL 8 Road Bike 2017. It’s constructed from their renowned 500 Series OCLV Carbon which is incredibly lightweight, but also remains strong and stiff throughout maximum power output and with the incorporated IsoSpeed technology that’s taken the pro-peloton by storm, it’s ready to tackle a wide range of terrain.
The IsoSpeed technology offered from Trek is evident within the rear end, fork and handlebars of the Domane SL 8, and as soon as you plant yourself on the saddle, you’ll feel the difference. The rear IsoSpeed decoupler separates the seatmast from the frame, allowing the seatmast to move independently from the rest of the bike, absorbing all the bumps and vibrations the road has to offer.
The rear decoupler is also completely adjustable depending on personal preference and/or what type of ride you’re on. Simply unscrew the lower bottle cage bolt, which determines the compliance of IsoSpeed, and slide the rear of the seatmast up or down. Less compliance is perfect for short, high-intensity efforts in the saddle on smooth roads, whilst more compliance is aimed towards longer rides, such as Gran Fondos.
Used in the fork and handlebar, IsoSpeed is a little different, though. Instead of an IsoSpeed decoupler, the fork and handlebar have increased vertical compliance to take the brunt of whatever surface you’re riding on. There’s a reason the Trek-Segafredo team use the Domane on the cobbles.
Equipped throughout the Domane SL 8 is Shimano Dura-Ace 9100 - Shimano’s top of the range mechanical groupset that can take on the rigours of everyday riding. Because it’s mechanical, this componentry is easily adjusted and repairable by the roadside, making it perfect for rougher terrain where vibrations can cause mechanicals.
Dura-Ace 9100 isn’t just durable, though, it provides high-speed, reliable shifting and with its 11-28 cassette, offers a wide range of gearing meaning you can choose the ideal gear to suit your style. Spin up the climbs or attack, it’s your choice.
Bontrager Paradigm Comp Tubeless Ready wheels and Bontrager R2 Hard-Case Lite 700x28c tyres finish off the Domane SL 8, offering unparalleled levels of traction for confidence inspired cornering and descending. The Domane offers wider tyre clearance, so you can chop and change your tyre choice depending on your riding style.
