There are bike dorks and then there are bike dorks. Today's podcast sees Gustav Gullholm, AKA Dangerholm on Instagram, take us through some of his wildest creations. How about a sub-30lb Scott Gambler downhill bike? Or his take on down-country, a 100mm-travel Spark that employs an ingenious dropper post integration system that ties it into the bike's rear-suspension? Of course, all of these crazy machines have also been scraped down to bare carbon... with a big ass knife. Yeah, we had questions for Gustav.
