JT. Steel Standard 253 - 420 Output sprocketRef : JTC01376A / 1077309003

JT Sprockets steel sprocket, reference JTF253.14, designed for replacements and gear ratio changes on urban, cross, and roadster machines. This type 253 sprocket with a pitch of 420 is a standard transmission component suitable for 420 chains and a wide range of small displacements. Its CNC machining ensures precise tooth geometry for consistent engagement with the chain.

• Material: steel (high-strength alloy SMC420)
• Number of teeth: 14
• Chain pitch: 420
• Type / version: 253 – Standard
• Machining: CNC for consistent finish and precision

Ideal for those adjusting the gear ratio to refine acceleration or top speed, this sprocket fits well on small trails as well as on cross bikes and lightweight roadsters. Its optimized design limits premature wear of the teeth and facilitates installation during a transmission overhaul.
