We challenged our friends over at GMBN to find out what the ultimate all-road bike is, a gravel bike or a mountain bike? But we weren't going to solve this question anywhere, so we went to the ultimate testing ground, Iceland!

In association with Moots, Reynolds, Cycliq, and Komoot.

Simon was joined by Neil for his icelandic adventure, GMBN vs GCN, gravel vs MTB, Drop bars and pretty skinny tyres vs suspension forks and flat bars. Just who would have the best tool for the job?

Over two days, and 200 kilometres Si and Neil traversed the Icelandic Highlands by bike. The guys aimed for the Icelandic summertime, but it turns out summer means something different over there, as the temperature hovered around 0 degrees Celsius in the daytime!

This was an absolutely incredible adventure over some of the most stunning terrain you can ride a bike on, and we'd love to know what you think of it. So leave us a comment down below this video!
