Sugar Cayne
Marshal Racing dropped a video on Instagram showing their prototype chain tensioning system at work. The system is made for their popular SR71 Blackbird carbon BMX race frame.

It’s made to simplify the chain adjustment process and guide the chain smoothly. I’d love to try this bike out
