Gustav Gullholm, who goes by the online persona of “Dangerholm” has been passionate about bikes all his life. Even as little kids, he and his friends spray painted their bikes and tried to upgrade and tune them.

And it simply escalated and grew from there. Ever since Gustav has been building custom bikes. It often starts as an idea based on a theme, such as pushing low weights to new extremes or trying to make bikes cleaner and better looking.

"Each year new bikes and components are released, but there is always room to personalize or optimize your bike. It can range from getting a colored set of grips to upgrading your drivetrain with ceramics to going "full Dangerholm". Either way - I think that while your bike is a tool (transportation, training, racing) it is YOUR bike so why not put a little bit of passion into it. Cliché as it may sound - life's too short for boring bikes." - Gustav "Dangerholm" Gullholm
