The REVERSE Lower Cup Base Ø49 mm 1.5 ZS49/30 is a robust semi-integrated headset lower cup designed for modern mountain bike and gravity-oriented frames. Built around the popular ZS49 standard, it allows you to run a 1.5" tapered or straight steerer fork in a compatible 49 mm head tube, ensuring a precise and secure fit. This lower cup is ideal for riders upgrading frames, swapping forks, or refreshing a worn-out headset while maintaining smooth steering performance and reliable bearing support on rough terrain.
Engineered for durability, the REVERSE Lower Cup Base is typically made from high-quality alloy to balance strength and weight, and it is shaped to protect the bearing from dirt and moisture when used with appropriate seals. Its semi-integrated design keeps stack height under control, helping you achieve a clean cockpit and confident handling. Whether you ride enduro, downhill, or aggressive trail, this lower cup offers a solid foundation for your headset assembly, making it a smart choice for riders who demand precise steering and long-lasting performance from their front end.
