Let us know what you think of this massive amount of data in the comments below 👇

To ensure that the results are as accurate as possible, the frames are the same (Orbea Orca), the tyres are the same (Continental GP4000s II), and the riding position is the same.

How is the test going to be conducted?
Once in the dry on each bike and once in the wet on each bike. So a total of four descents.

The location for the test is a portion of the descent of the Passo Pordoi in Alta Badia, Italy.

How are the results going to be gathered? Simon will be using GPS data from his Wahoo Elemnt, Powermeter data, heart rate measurements, and an accelerometer.

Were disc brakes faster? Well, you are going to have to watch to find out.
