The ORBEA TRAINER AXLE 12x183x2P.1x35+NUT is a dedicated thru-axle solution designed to make your bike fully compatible with modern indoor trainers. Many frames with 12 mm thru-axles cannot be clamped securely in a trainer using the stock axle, which is where this trainer-specific axle comes in. It replaces your existing rear axle and provides the correct length, thread, and secure interface needed for stable mounting, helping to protect both your frame and trainer from unwanted movement or stress during hard efforts.
Engineered for durability and reliability, this axle is built to withstand repeated high-torque sprints, long endurance sessions, and frequent installation and removal. The included nut and specific spacing help ensure a precise fit, while the robust construction resists bending and wear over time. By using a purpose-made trainer axle, you reduce the risk of damage to your original axle and improve overall stability, resulting in a smoother, quieter, and more confidence-inspiring indoor training experience, whether you are warming up for races or following structured workouts at home.
