BSD Grime Frame – Denim Cox Signature
The BSD Grime Frame is Denim Cox’s signature model, built for raw, aggressive street riding. Designed around his fast, technical style, the Grime is all about responsiveness, strength, and control when things get heavy.
With a 12.8"–13.2" rear end, the Grime delivers a quick, snappy feel that’s perfect for manuals, spins, and tight technical riding. Paired with a steep 75.5° headtube angle, the front end stays sharp and reactive—ideal for nose tricks and fast line adjustments.
The frame features an invest-cast chainstay yoke, allowing for improved tyre clearance even when slammed, while also increasing rear-end stiffness for better power transfer and durability.
A 9" standover height keeps things responsive and easy to throw around, while the classic 71° seattube angle maintains a familiar, balanced feel. Built from Sanko Japanese seamless 4130 CrMo tubing with a triple-butted construction, the Grime is made to take serious abuse while keeping weight around 5lbs.
Finished with details like invest-cast dropouts, an integrated seat clamp, and a clean brakeless design, this is a frame built for riders pushing modern street riding to the limit.
