Key benefits - Tailored adjustment for a perfect bike to trainer fit: easy-to-adjust width with a complete set of spacers for precision alignment. - Easy installation and use: replace your bike's existing thru-axle with this adapter for a clean, stylish look and improved wear resistance. starts indoor training quickly with no special tools or expertise required. - Durable, high-quality construction: alloy material, wear-resistant and sturdy, not easy to deform or rust, for long-lasting reliability. - Maximized bike compatibility: three thread pitch options P1.0, P1.5, P1.75 and suitable for 135-148mm rear axles, enabling seamless bike-trainer connections across a wide range of bike models. What this solves - Simplifies indoor training setup by allowing a quick, tool-free swap to a trainer-compatible thru-axle. - Provides a secure, stable connection that resists wear and corrosion during frequent use. - Reduces the need for multiple adapters by supporting common rear-axle widths and thread pitches. 2-3 practical use scenarios - Scenario 1: You have a road bike with a thru-axle and want to start indoor trainer sessions quickly. Remove the existing thru-axle, install this adapter with the spacers to achieve the desired width, and you’re ready to ride. - Scenario 2: You own multiple bikes with different rear-axle standards. Use this skewer to accommodate various models by selecting the appropriate thread pitch (P1.0, P1.5, or P1.75) and adjusting width with spacers. - Scenario 3: You train regularly and value durability. The alloy construction provides wear resistance and corrosion resistance, supporting long-term use with minimal maintenance.
