It was only last week that Canyon announced it would be offering disc brake options for each of its road bike ranges. Straight off the back of that news, here's the disc brake version of Canyon's popular Ultimate road bike.
This model, the Ultimate CF SLX Disc 8.0 Di2, retails for £4,399/ €4,899 and sits in the middle of three disc brake options, along with a disc frameset that'll retail for £2,199/€2,999

Now, if you're reading this with your stomach churning at the sight of those shiny bits at the centre of each wheel then don't worry, the rim brake Ultimate range isn't going anywhere. For now.
The transition to discs has meant some major changes to the Ultimate chassis. The frame and fork both use 12mm axles, 142mm at the rear and 100mm wide up front. To deal with the extra forces involved, the Ultimate disc frames feature more material, particularly at the non-driveside of the frame and fork, where the Flat Mount calipers are mounted.
Canyon claims that these changes have added just 70g to the weight of each frame, yet that total doesn't account for the weight difference in the braking hardware itself, which will be more significant. We weighed our size medium test bike in at 7.79kg/(17.2lbs). A like-for-like comparison isn't easy to make, that's because this model uses Mavic's weightier, disc-specific Carbon Cosmic Pro wheelset, but we think it's fair to say that you're looking for a weight penalty of around 1kg to switch to discs.
