Its 32mm internal width enhances tire stability, making it perfect for wider tires and aggressive riding styles.

Built with precision, this rim features 28 evenly spaced spoke holes for balanced wheel builds. Its welded construction ensures a true wheel and consistent performance over time. Compatible with disc brakes, the Duroc SD37 is tailored for mountain bikers who demand consistent braking power and reliability in muddy, rocky, or technical trails.

Style & Use Case:

Finished in sleek black, the SunRingle Duroc SD37 rim offers a modern, aggressive aesthetic that complements any mountain bike setup. Whether you're conquering rugged downhill trails, tackling mountain bike races, or enjoying technical trail riding, this rim is engineered to handle high-impact rides with confidence. Its tubeless design reduces weight, puncture risk, and offers superior traction, making it a versatile choice for serious mountain bikers.

Innovative & Differentiating Features:

- Super-Duty bead hooks for added strength and impact resistance
