Dangerholm: The Mad Genius Behind the World's Most Boundary Pushing Bikes

Best known for heavily modifying carbon fiber mountain bike frames and components to shave grams and hide every cable, Dangerholm set out to create two wild gravel machines based on Scott's Spark RC and Scale frames. But the real talking point is the wheels used on both bikes: fully custom carbon rims with a 45mm inner width, 52mm on the outside, and a stepped height of up to 70mm. In other words, absolutely massive. But are they too wide?Levy has Dangerholm explain how the design is essentially a hidden rim inside of a fairing, tire choices, the upsides that go far beyond aero benefits, and how you'll never know what works if you don't go a bit too far sometimes.
