This latest version of the Domane SLR 9 has already graced the pages ofPeloton. To recap, it’s full of great features, like a front and adjustable rear IsoSpeed decoupler design that helps create a smoother ride, tidier cable routing and a more aerodynamic design. It’s a smoother, faster bike—all good news.

The official tire clearance is listed at 38mm. But as you can see, 40mm Bontrager GR2 tires can squeeze in.

And it doesn’t look bad, either. In fact, it looks pretty damn good. Most “endurance” bikes have a tendency to look, well, put diplomatically, not as aesthetically pleasing as their race-geometry-oriented brethren. But the Domane sheds that mold. This rig has been mistaken for a Madone multiple times on group rides and from passersby at the coffee stop. That is to say, it looks fast. And it feels fast too. We’d race this in a crit or a road race. And we’d just as happily race it on gravel. In fact, we have.

When Trek was presenting this bike to us in Italy last summer and got to the part about tire clearance, the wheels started turning in our heads—wheels adorned with thick tires. The officially listed tire clearance is a whopping 38mm, massive for what is ostensibly a road bike. Naturally, we pushed the limit, squeezing in 40mm Bontrager GR2 Team Issue tires mounted on the excellent Bontrager Aeolus Pro 3V gravel wheels. Granted, the tread on the GR2 tires is low profile, but 40mm tire clearance, even if it is a little tight, is bona fide gravel bike territory. Sticking by Trek’s clearance recommendations is probably the best call, but for those craving maximum volume, this bike delivers.

The biggest item holding us back from declaring the N+1 debate dead is weight. As we received it with Bontrager Aeolus XXX 4 wheels, this Domane hovers in the 18-pound region for a size 58. Not bad, but not great either. But on the flip side, substituting in the gravel wheels only pushed the weight to a hair over 19 pounds. That’s not at all unreasonable for long days of gravel in the saddle, especially when that saddle sits atop decouplers that smooth out road chatter.

The future of bike design has arrived; we can’t see where it goes from here.
