- High-performance construction: Made from aircraft-grade alloy and precision machined for consistent strength, heat resistance, and abrasion resistance. Designed for durable, long-term use under normal riding conditions. - Lightweight design: Lighter than skewers made from other materials, so they reduce overall bike weight without sacrificing strength or security. - Tool-free quick release: Cam-lever quick release allows fast removal and installation of wheels by opening or closing the lever—no tools required. Compatible with standard quick-release wheel systems. - Compatibility and size: Sized for most disc-brake bikes with a 130 mm front axle spacing and 170 mm rear axle spacing. Ideal replacement for bikes with those hub dimensions. How this solves common problems - Speeds maintenance and transport: Quick, tool-free wheel removal reduces time spent on roadside repairs, train or car transport, and storage. - Lowers ride weight without compromising reliability: The aircraft-grade alloy offers a good balance of stiffness and low mass, improving handling and hill-climbing efficiency. - Built to handle heat and wear: Heat and abrasion resistance keeps performance consistent over repeated use and exposure to braking heat common with disc brakes. Key specifications - Material: Aircraft-grade alloy - Features: Precision machining, high strength, heat and abrasion resistance - Compatibility: For disc-brake bikes with 130 mm front and 170 mm rear quick-release spacing - Operation: Cam lever quick release; no tools needed Practical use scenarios 1. Daily commuting: Remove wheels quickly to fit your bike in a car trunk or public transport, then reinstall in seconds without tools. 2. Trail or gravel rides: Rapid wheel changes after a puncture or to switch wheels/tires during a ride, minimizing downtime. 3. Race or training prep: Reduce bike weight and speed wheel swaps during practice or event pit stops, while maintaining secure wheel retention. Notes for buyers - Confirm your hub spacing is 130 mm front and 170 mm rear before purchase to ensure fit. - Follow proper quick-release adjustment and wheel seating procedures to ensure safe operation.
