Danny MacAskill has been massively influential. He burst onto an already-established scene (street trials) and just killed it. He was / is an order of magnitude better than the next best riders and basically turned the scene on its head, and got it noticed by the wider MTB audience (as well as the non-cycling world). He made everything bigger, faster, more technical and more creative than before.
Akrigg has brought his undeniable trials skills to a new environment. He’s done stuff no one has thought to do before and he has an eye for some very creative lines. In the past, a lot of what he’s done has just been riding trials on the ‘wrong’ bike, although this most recent video does extend that a bit – he’s definitely growing into riding that Mongoose and using the potential of a full sus bike more. I just can’t shake the feeling that a lot of his lines would be easier and less impressive on a proper trials bike, and the best riding videos are about pushing the boundaries of what’s possible, not what’s possible on a particular bike*.
I love Akrigg, but put it this way: I bet Danny could turn his hand to what Akrigg does, but the reverse would never happen.
*Although I accept that road bike party was the coolest video of recent years.
