Race handling, with one-finger braking

Alongside the German brand’s Aeroad aero bike, the Ultimate is Canyon’s all-around race bike, with steep angles, a short wheelbase and a low front end.

Like many brands, Canyon has multiple levels within a given bike family, and the Ultimate CF SL Disc 9.0 sits just behind the Ultimate CF SLX, with the primary difference being the type and cost of the carbon.

While you can tell the difference with a scale, you can’t with your eyes. Similarly, the SLX and SL frames handle the same as they come out of the same molds, with the same geometry.

For me, the bike hits the sweet spot of ride characteristics. Push harder to accelerate, and the rigid chassis launches forward before you’ve completed a pedal stroke. Lean gently with your hips, and the front end goes exactly where you want. Stand up, and the bar/stem/fork will meet you with firm leverage for muscling the bike. But the VCLS seatpost, with a healthy extension thanks to a gently sloping top tube, soaks up the bumps like a sponge without ever feeling too mushy under hard pedaling.

For those who prefer slightly more upright positioning, Canyon has the Endurace platform. Personally I like the lower front end for getting weight on the front tire and my torso out of the wind as much as possible.

A stiff pedaling platform with the comfort of a flexing seatpost? Yes, please

I rode the bike in the days before Eurobike in Austria with other journalists, and we had the chance to do some good climbs and subsequent sharp descents. I’ve been going back and forth between test bikes with rim brakes and test bikes with disc brakes, and the difference is just laughable. While today’s rim brakes are quite good, the deceleration return you get for the amount of force at the lever is just worlds apart from a good hydraulic system.

Do you need hydraulic discs on road bikes? Of course not. In addition to a number of guys on rim brakes, Stages marketing director Matt Pacocha descended alongside us on his Ritchey travel bike with old-school cantilever brakes. But are hydraulics better at slowing you down? Of course they are.

At 7.7kg / 16.9lb (in the size Medium I tested), the bike isn’t a featherweight, but it is right in line with other carbon bikes with Ultegra-level gears and hydraulics.

Plush ride, courtesy Conti and a Canyon post

Two things tag-team the relatively plush ride of the Ultimate: Continental’s Grand Prix 4000S II clinchers and Canyon’s own VCLS seatpost. Conti’s GPs have been a perennial favorite of many riders for years. They tested well in our recent rolling-resistance test at Wheel Energy, their grip is reliable and durability — for a race clincher — is good.

One thing I learned at Eurobike this year is that the GPs are also the most aero tire, when normalizing for width, of any standard clincher on the market. This is according to Jean-Paul Ballard of SwissSide, a former Formula 1 engineer who has been studiously testing every aspect of road and triathlon bikes. Evidently the tread pattern acts as a laminar trip layer, smoothing the airflow around the wheel.

In any event, Canyon doesn’t skimp on rubber, nor does Conti skimp on width, with the labeled 25mm clinchers measuring much wider on most rims.

The VCLS seatpost also does wonders for ride quality. We lab tested this post and a few others last year, and the deflection numbers don’t lie.
