Christmas appears to have come early in the Cycling Weekly office...Last week we had a first look at the new Canyon Ultimate CF SLX Disc and this week we can reveal and exclusive first look at the Canyon Aeroad CF SLX Disc, as the bike we have here is the first and only one presently in the country. We first found out about the Canyon Aeroad CF SLX Disc when Katusha’s Alexander Kristoff perhaps accidentally posted a picture of the new bike on social media.

That was a prototype, but finally, after what seems a big wait, here is the bike.

Frame

The first thing to point out that is that this is the frame the pros will ride when they use discs in 2017.

Now, one of the things I am sure you want to know is, how does the weight differ from the non-disc version? The Canyon Aeroad CF SLX Disc 8.0 Di2 we have here hits our scales at 7.76kg making it roughly 600g heavier than the equivalent non-disc version. It’s not much at all, considering the superior braking and is commendable for an aerobike.

What I do have to point out is that the equivalent non-disc Aeroad is £600 lighter on your wallet though.

The increase in system weight comes from a combination of changes, necessary for the inclusion of hydraulic discs plus thru-axels. Disc brakes create increased braking forces on the frame, so Canyon has beefed up the frame in a few key areas by adding additional carbon to the tune of about 70g. Most of this is on the non-drive side, where the flat mount calipers are situated.

The frame looks awesome though and the loss of the rim brake callipers has created a really tidy look. I have no doubt this bike will turn heads, but if the stealth black isn’t for you, there is also a red option.

Specification

There will be a full range of models once SRAM Red HRD and the new Dura Ace groupsets are available, but in the meantime Canyon is offering Ultegra mechanical and the Di2 you see here. As is customary with Canyon you get a full Ultegra groupset too, with no stocking filler components dropped in.

160mm rotors front and rear on the Canyon Aeroad cf slx Disc

Interestingly Canyon has opted for a Continental GP4000 23mm tyre front and 25mm tyre rear. This is no accident, and is a very deliberate choice. Having spoken to some of the worlds top aerodynamicists, the consensus is that the GP4000 is the most aerodynamic commercially available tyre.

It was not designed to be, but just happens to be a case of serendipity. Further to this, being slightly narrower is optimal over the lower rolling resistance of 25mm tyre at speeds typically over 35kph. It would appear that Canyon has done its homework, hence the 23mm front and 25mm rear.

>>> Are wider tyres faster?

Similar to the Ultimate Disc, the Canyon Aeroad CF SLX Disc features Shimano’s top spec BR-RS805 flat mount calipers and 160mm Ice Tech rotors front and rear for ‘optimal power and breaking modulation.’

I am glad Canyon has gone for 160mm rotors over 140mm. A bike we have previously reviewed – the Merida Scultura Disc, is equipped with 160mm rotors front and rear and the main advantage is superior heat dissipation, which is sensible when you consider mountain bikes have bigger rotors, yet the braking on road bikes is likely to be more sustained and can be at higher speeds.

Wheels are disc brake specific, 62mm deep Reynolds Strike tubeless ready carbon clinchers. They have an internal rim width of 17mm and a claimed weight of 1700g. Overall, they seem like a great pairing on paper for the Canyon Aeroad CF SLX Disc and we look forward to seeing how they roll.

There is also a mechanical Ultegra version of the Canyon Aeroad CF SLX Disc for £3799

The saddle is a Fizik Arione R5 and the bars are Canyon’s proprietary aero cockpit. One final detail – the bike uses 12mm thru-axels and Canyon’s new detachable levers which are said to save in the region of one watt. Every little helps!

Regardless of the savings, they look really smart. There is also a women’s specific model of the same bike you see here too.

Value

Even with the rise in prices of imported goods from a weaker Brexit Pound, Canyon continues to off excellent value for money. As mentioned, the disc brake model is £600 more expensive than the non disc version with the same Ultegra groupset and Reynolds wheels.

Although this is top spec machine with a high price, the cost is highly competitive against the likes of Cervélo, Pinarello and BMC. If you were to buy one of their premium frames, with a comparable spec, your wallet would be considerably lighter.

Verdict

The Canyon Aeroad CF SLX Disc is a stunning looking stealth bomber of a machine that will no doubt turn heads. Intelligently specced and commendably light for aero, disc equipped machine, I can't wait to see how it rides. Hopefully the slight beefing up of the frame won't have compromised it. I will be updating this page with a full review once I have ridden it, so stay tuned.
