The BSD Jonesin is Sam Jones’ signature chainring, purpose-built for street BMX. It features an 8 mm-thick 7075 T6 aluminum chainring with a sturdy solid design. Mounted directly in front is a high-impact plastic guard that protects the chain and chainring teeth during grinds and contact with rails or ledges. If the guard wears out over time, it can be replaced without needing to replace the entire chainring. The Jonesin attaches to a compatible BMX crankset using a standard chainring bolt. The 24 mm interface can also be used with 22 mm and 19 mm crank axles using the included adapter rings. With 25 teeth and a design for 1/8-inch BMX chains, the chainring is ideal for compact street gear ratios.
