While not particularly scientific, this video from the Global Cycling Network has some fun with the age-old debate of which is harder road cycling or riding a mountain bike. Press play to see presenters Simon and Matt challenge one another to see which is fastest in a route from A-B. The rides take place in the beautiful Alta Badia region of Italy.
Which do you think is harder? Let us know in the comments below. And be sure to check out more videos on RoadBikeReview.
