Trek's Domane SLR 7 Disc gets flexible at both ends

Wide rubber, disc brakes, and a couple more endurance racing tricks

This article originally appeared on BikeRadar

Trek's full-carbon Domane SLR 7 Disc is designed to mute rough roads and bumps thanks to the Wisconsin firm's proprietary IsoSpeed decouplers – pivots in the frame that allow subtle fore-aft movement. Wide rubber, thru-axles, disc brakes, and a full Ultegra Di2 spec look to add to the capabilities.

Twice as smooth

Trek claims the Domane is "the smooth advantage" – and there's plenty of technology to back that boast up. First and foremost are Trek's IsoSpeed decouplers front and rear.

The previous Domane featured a pivot at the junction where the seat tube is usually locked solidly into the top tube and seatstays, and this new version takes a good idea even further. Trek's decoupler now finds its way up front at the steerer tube. Deflection is allowed fore and aft, but not side to side. 

The Domane touts the increasingly familiar endurance road bike standard of disc brakes, thru-axles front and rear, and plenty of seatstay and chainstay clearance for wide, cushy, 32mm rubber.

Where it differs from its competition is in the way the IsoSpeed system minimizes the inputs the bike's frame tubes have upon one another. It's more than just a compliant seatpost, like those employed on BMC's GranFondo GF01 Disc, Canyon Endurance CF 9.0 Pro and others. And on this new Domane, the previously fixed amount of forgiveness can be adjusted via a sliding bolt to suit individual riders, or specific courses.
