Canyon Endurace: Installation of Dura-Ace R9170 Components

Finally, after taking a detailed look at each of the new Dura-Ace components, and also the Canyon Endurace frame, it is now time to install everything onto the bike!

From a bare frame, it takes quite a bit of work to assemble all of the components. The most tricky and troublesome part are the hydraulic disc brakes, which takes some time and also requires other people to help with the bleeding of the brakes.

Full Dura-Ace R9170/R9150/R9100 groupset that will be going onto the bike!

New Dura-Ace brake rotors installed onto the Reynolds Assault wheelset

Dura-Ace R9100 11 speed 11-30T cassette installed onto the rear wheel

Front hydraulic disc brake caliper with adapter

Dura-Ace bottom bracket, press fit type SM-BB92

New 11 speed chain CN-HG901. I did not reuse the stock 11 speed chain as it went onto the Dahon MuEX along with the cassette, rear derailleur and crankset.

There are no photos of the installation process, as my hands are usually working on something, or is greasy or oily. What you will see here is the final result of the full bike assembly.

Integrated handlebar and stem, with shifters installed, bar tape wrapped and Garmin in position.

Shiny new Dura-Ace Di2 road shifter with hydraulic disc brakes, ST-R9170.

Comparing the geometry to my other hydraulic disc brake bike, the Avanti Inc 3, the reach is actually a little bit shorter!

Junction A located at the front of the downtube, in an unconventional place.

Rear hydraulic disc brake caliper with adapter for 160mm rotors

Front hydraulic disc brake caliper, also with adapter for 160mm rotors

Big and chunky Dura-Ace R9100 crankset! 50/34T compact size, with 165mm crank arm length.

Dura-Ace Di2 front derailleur

Dura-Ace Di2 rear derailleur, with Shadow construction for a low profile

Overall view of the 2x11 speed Dura-Ace drivetrain

Fresh bike build with no accessories such as bottle cages or lights installed. With all components being black in colour, the frame colour really stands out!

Clean cable routing, with the cable or wires visible only in between the stem and the head tube. Relocating Junction A away from the stem did make it look a bit neater, but not by much.

Full bike specifications and weight

The theoretical full bike weight (without pedals) is about 6.9 kg, which is a bit different from the actual weighed value of 7 kg. Not a big issue at all, as this is still a lightweight bike! More so given that this is a hydraulic disc brake setup, which is roughly 300 grams heavier than a mechanical brake caliper setup.

The only place where significant weight can still be shaved will be from the wheelset, where a tubular wheelset can reduce maybe another 300 grams. Weight savings from other components will be minor and not really cost effective.

With such a nice road bike setup, the limiting factor is not the bike but the rider, as it is most of the time. Although I am not a pro rider or even a high mileage rider, I can still appreciate riding a good road bike.

Some people have this theory that if you don't ride so often, you don't need such a good bike. However, I feel differently. If I don't ride so often, then every ride is precious and I would like to ride a good bike on these rides! Life is too short to waste on riding lousy bikes, so if you can, get a nice bike that you can afford and ride it well.
