Wolf Tooth Rear Axle

Wolf Tooth Rear Axle is a precision-engineered 12mm thru axle designed to do more than simply hold your rear wheel in place. Built to aerospace-level standards in Minnesota, this axle improves frame protection, clamping efficiency, and long-term durability—making it a smart upgrade over many stock options. At the core of its design is a captive stainless steel washer positioned under the axle head. This small but critical detail reduces friction against the dropout face, helping to protect high-end carbon and alloy frames from wear. By minimizing friction, more of your applied torque translates directly into clamping force, creating a stiffer, more secure wheel-to-frame interface. The washer also prevents galling or seizing, making wheel removal smoother over time. Machined from high-strength 7075-T6 aluminum, the Wolf Tooth Rear Axle balances lightweight performance with structural integrity. Whether you’re replacing a lost axle or upgrading a stock component, this is a dependable solution for riders who value precision and durability. Compatibility Diameter: 12mm rear thru axle Axle Length: Compatible within +/- 2mm tolerance Fitment: Axle length is independent of hub dimensions Important: Confirm axle length, thread pitch, and thread length for proper fit Wolf Tooth Rear Axle Specs at a Glance Weight: 167mm – 42g | 172–180mm – 43g | 187–192mm – 46g | 198mm – 47g Material: 7075-T6 aluminum with stainless steel washer Tool Interface: 5mm hex key Max Torque: 12 Nm Manufacturing: Made in the USA Design Benefits Frame Protection: Captive washer reduces friction and protects dropout surfaces. Improved Clamping Force: More torque translates into secure wheel retention. Smooth Removal: Minimizes sticking and galling for easier service. Lightweight Strength: Aerospace-grade aluminum construction keeps weight low without sacrificing durability. For installation, apply a small amount of grease to both the washer and threads to ensure smooth torque application and long-term reliability. Riders who frequently travel or train indoors can also pair this axle with compatible axle caps or trainer caps for added protection and versatility. Final Take The Wolf Tooth Rear Axle is a refined upgrade that improves performance where it matters—clamping efficiency, durability, and serviceability. If you’re investing in a high-quality frame and drivetrain, this axle ensures your wheel connection is equally dialed.
