Description

#35 Pitch 30-Tooth Steel Sprocket – 7/8" Bore, B-Type Hub


The #35 Pitch 30-Tooth Steel Sprocket with a 7/8" bore and 1/4" keyway is a reliable and durable solution for mid-range gearing setups in go-karts, mini bikes, small engine drivetrains, and custom power equipment.


This sprocket features a B-Type hub (single-sided), providing added strength and support without increasing overall width, making it ideal for tight drivetrain configurations. With its 30-tooth count, it strikes a solid balance between acceleration and top speed—ideal for general-purpose builds or all-around performance.


Manufactured from heavy-duty, hardened steel, this sprocket is built to withstand tough riding conditions and repetitive use while maintaining smooth, efficient power transfer.

Always verify your chain pitch before ordering—this sprocket is designed for #35 roller chain systems.
