Canyon’s new Aeroad bike uses a unique Aerocockpit bar & stem combo that delivers more adjustability than any other integrated cockpit solution we’ve ever seen. As top road bikes move towards completely internal cable routing, Canyon’s direct-to-consumer business model meant they couldn’t just ship out a bunch of premium aero road bikes that only a professional mechanic could set up.

So they went back to the drawing board – even taking inspiration from quill stems of old – to develop an easy-to-use Aerocockpit that offered both no-cut stem height and bar width adjustment!

It isn’t often that a new pro-level bike debuts, and the first thing we think is… “wow, that’s a pretty cool handlebar”.

But the all-new carbon Canyon CP0018 Aerocockpit on the latest Aeroad is truly a unique approach to the concept of a “one-piece” integrated aerodynamic bar and stem combination.

In fact, half of what makes the new Aerocockpit unique is that it isn’t one-piece, but rather three – featuring detachable ‘cockpit wings’ that allow the rider to change the width of their bars by 40mm whenever they feel the need. And the other is a nesting threadless carbon quill stem that allows for 15mm of height adjustability, without needing to cut the fork’s carbon steerer tube.

How does bar width adjustment work?

By simply starting with what seems like a regular integrated bar & stem combo, the new CP18 Aerocockpit essentially cuts off the bar just where you would finish off your bar tape wrap. Then, it gets a set of tops & drops that slide into the central section of the handlebar (into what would be the extended clamping area of a conventional bar.)

Underneath, a pair of bolts on each side secure the bar in place through holes in the extension ‘cockpit wings’ in one of three positions: -10mm, 0mm & +10mm on either side. This gives three bar width options of +/- 20m from the standard middle position or a max variance of 40mm in bar width (ignoring the possibility of setting one side wider than the other, which could actually help riders with arm length differences.)

Beyond the ability to just adjust your bike fit, the removable wings that made it easier for Canyon to box the Aeroad for delivery, also mean travel with the bike is easier too. Simply loosen the four bolts under the bar, and the two cockpit wings can be folded down for more compact travel, without even needing to remove the bar from the steerer tube.

How does stem height adjustment work?

The 15mm of height adjustability of the Aerocockpit works by getting rid of the convention of cutting the carbon steerer tube to length, using a expander inside of the steerer to tension the headset bearings, and a clamp on the outside of the stem that presses against the upper section of the steerer.

Then a clamping screw, presses a fork insert just against the front way of the fork’s steerer. This allows more opportunity for the ‘stem’ to move up and down on the steerer tube, without needing to cut it.

The result, you can add a 5mm, 10mm or 15mm stack of open spacers under the stem to change your bar height without needing to cut the steerer or adjust the internal cabling.

Canyon CP0018 Aerocockpit – Availability

For now, you will need to buy a new Canyon Aeroad to get the newest Aerocockpit. But as much as it looks like a completely proprietary system, the new integrated cockpit appears to work with a conventional 1 1/8″ upper steerer tube, and the outer diameter of the cockpit’s carbon quill is a standard 1 1/4″ meaning it works with semi-standard upper headset bearings – like those in the old Aeroad. The fork steerer drilling and fork clamping insert are obviously unique, but there’s plenty of reasoning to think that Canyon could make this available on their other bikes in the future. (You simply need a frame with a 1.25″ upper headset bearing and a tapered fork with a 1.125″ diameter.)

If it does become available separately… How much will it cost? That also is unclear. But Canyon’s top H36 Aerocockpit already sells for 400€, so we wouldn’t be surprised to see this more adjustable one selling at a good bit more than that.

    I don’t want to throw Canyon under the bus yet, as I would hope they’ve done some extensive real-world testing on those bars on some seriously gnarly stresses. My initial reaction is of potential weakness when sprinting, When descending chunky B roads or washboarded gravel in the drops, pulling on a steep climb… That area is subjected to a myriad of forces from flexing and muscling the bike around that I cannot fathom how those bars will fare after a couple of seasons hard riding/racing.

      • advcyclist on

        Potential weaknesses from adding multiple mechanical fasteners to a stressed member of what is, typically, a singular unit.

        Having witnessed failures of handlebars from excessive torque of integrated shifter/brake hood clamps, as well as from cumulative effects of salt from perspiration; these bars adding two additional potential points of failure does not exactly paint a picture of cohesive strength over time. Bike shop mechanics are more likely to correctly use a torque wrench and fastener compounds to the factory spec… the average rider doing DIY maintenance in his/her home or garage; not so much.

        Any time mechanical fasteners are introduced to a stressed span; the material around it must be built up and enhanced to offset the applied torsional forces.

    It looks like there is a few inches of overlap in the coupling. The screws really aren’t bearing that much force. The clamp diagrams (stem and seatposts) concern me more than the handlebars.

  3. Robert Westendorf on

    If you spread the bars, does that leave a section exposed of a smaller diameter? I’d like to see a picture of how it looks, because if the exposed section is a different size I don’t think I’d like that look.

  4. Brian on

    Integrated and aero is cool until you need to have the headset bearings serviced or replaced and suddenly a simple task becomes very expensive and will take even a professional mechanic a long time to do.

  5. toffee on

    15mm of variation is not enough. I see so many bikes with 40mm of spacers. I think there is a lot of complication here just to make life better for Canyon, and not necessarily better for the consumer.

    Also seems that stem length has been left out of the equation. Unless you get a choice when purchasing.

    People need to step back and realise how good a design the bar and stem combination is and what it allows.

    • Involuntary Soul on

      if you need 40mm of spacers that means the frame stack is way too low for the raider, he/she should get a size larger or a frame with more relaxed geometry

    This looks like a lawsuit waiting to happen. Carbon is strong, but Hambini is going to filet Canyon again. Unless Canyon overbuilt it, the weight of which defeats the purpose.

    • Robin on

      How exactly does the weight “defeat the purpose”? Aero trumps mass in most riding, and the mass of that handlebar would have to be really large to offset the aero benefits, even if the aero benefits are small.

      Lawsuit waiting to happen? Can you provide your engineering analysis?

      Hambini? Who cares what he says?

  7. Gillis on

    I’m wondering where all the extra housing goes to accommodate all this adjustability. Wires, sure. But hydraulic line and/or cables?

  8. David Fortino on

    What do you do to cover the gap if you expand the bars? I’m not certain is bar wrap would be enough. It’s almost as if there should be little carbon spacers that you could slide in there to fill the newly created void.

  9. Chris on

    Will be curios to know about weights and price for replacement “stems” so you can adjust your reach. Honestly, this might not be much heavier than a standard separate bar – stem combo.

  10. Robin on

    If you go to CyclingTips article on this bike and these bars, you can see a photo of the cross-section of these bars. It looks like they are overbuilt and appear fairly robust.

  11. Dinger on

    Cockpits and forks couplings are litigation drivers for bike companies. I would expect this has been tested up and down before being approved.
