Full-on race bikes are awesome for pushing hard and ripping legs off your riding posse. They maneuver on a dime and can seemingly ascend on their own. Up until a few years ago, those sentiments would never, ever be attributed to an endurance, marathon, gran fondo or gentleman’s bike. Not anymore. Thanks to race-proven endurance designs, like the Domane, the sweet spot of the market now has a no-compromise, smooth race-machine.
Introduced earlier in 2014, the Domane 6.9 Disc not only offers the sweetness of the IsoSpeed Decoupler, but in disc brakes as well. And well, not to be outdone, the Domane 6.9 also sports thru axles at both ends — not something that’s surprisingly-difficult to find on the current crop of disc-equipped road bikes.
So, let’s start there. Up front, it sports a 15QR axle for stiffness in and out of the saddle and for no-nonsense braking power. In the back, Trek has opted for mountain bike standards in a 142×12 thru axle. Both of those axle sizes, shapes and widths are a dime-a-dozen in the MTB world, so any bike shop and most mountain bikers will rejoice in the simplicity — in spite of changing to thru axles.
Constructed of 600-series OCLV carbon fiber, the frameset is no slouch — it’s the best frameset that Trek offers in the Domane. Therefore, it most certainly checks off all the boxes for vertical compliance (and then some) as well as lateral stiffness. Having ridden the Domane, it is an impressive bike that loves to be ridden hard and rewards the pilot with all-day comfort.

The Bottom Line
The Trek Domane 6.9 Disc is not cheap, but it delivers on every promise it makes. The spec is outstanding and the performance will, no doubt, stack up against any full-blown race bike on that market. You’ll ride more refreshed and have a heckuva lot more fun doing it. If you want to save a bunch of coin, the 6.2 Disc is $5139.99 and sports the venerable Ultegra mechanical drivetrain — no slouch either.
