The Shimano Rear Hub 120/36 Side Thread is a dependable foundation for building or refreshing a rear wheel on a classic or utility bike. Designed around a 120 mm rear spacing and 36 spoke holes, it is ideal for single-speed, track-style, or older road and city bikes that use narrower rear triangles. Shimano’s proven hub engineering focuses on smooth rotation, reliable sealing, and long-term durability, making this hub a smart choice for riders who value consistent performance and low maintenance.
This rear hub uses a side-threaded design to accept compatible freewheels or accessories, offering a straightforward and familiar setup for many traditional drivetrains. The 36-hole configuration provides a strong, stable base for wheel builds intended for everyday riding, commuting, or light touring. Whether you are restoring a vintage frame, upgrading a worn-out hub, or assembling a custom wheel, the Shimano Rear Hub 120/36 Side Thread delivers the reliability and serviceability that mechanics and riders have come to expect from Shimano components.
