The Mad Genius Behind the World’s Most Boundary Pushing Bikes
Best known for extensively modifying carbon fiber mountain bike frames and components to reduce weight and conceal cabling,Dangerholm recently created two custom gravel bikes based on Scott Sports‘ Spark RC and Scale frames. A key feature of these builds are the fully custom carbon rims, boasting a 45mm inner width, 52mm outer width, and a stepped height reaching 70mm.
The design incorporates a hidden rim within a fairing, influencing tire choices and offering benefits beyond aerodynamics. The concept, as discussed in a recent Velo Podcast interview with Levy, emphasizes the importance of experimentation to determine optimal performance.
Dangerholm and Carbon Fiber Modification
Dangerholm, whose real name is Matthew Prior, is a prominent figure in the cycling community known for his meticulous approach to bicycle modification. He specializes in reducing the weight of bikes and improving their aesthetics through innovative carbon fiber work. His Instagram account showcases numerous examples of his custom builds and modifications.
Scott Bikes: Spark RC and Scale Frames
Scott Sports is a Swiss-based manufacturer of bicycles, winter sports equipment, and sportswear. The Spark RC is a cross-country race bike known for its lightweight design and efficient suspension. The Scale is a hardtail mountain bike also focused on performance and low weight. Both frames served as the foundation for Dangerholm’s gravel bike projects.
Custom Carbon Rim Design
The custom carbon rims developed by Dangerholm are notable for their unusually wide profile. the 45mm inner width is significantly wider than typical gravel rims, which generally range from 21mm to 25mm. This design aims to optimize tire volume and perhaps improve handling and comfort. The stepped height, reaching 70mm, contributes to the rim’s structural integrity and aerodynamic properties. The concept of a hidden rim within a fairing is a unique approach to rim design, potentially offering aerodynamic advantages while maintaining structural strength.
