Wahoo KICKR Thru Axle Adapter Kit

The Wahoo Fitness KICKR Thru Axle Adapter Kit is an accessory designed to let bikes with thru‑axle rear hubs be mounted securely to compatible Wahoo smart trainers. Many modern bicycles use thru‑axles instead of quick‑release skewers, and this adapter kit allows you to convert your trainer’s rear interface to accept common thru‑axle standards so you can train indoors without swapping wheelsets. It is intended for use with Wahoo trainers that support thru‑axle adapter kits, such as the KICKR CORE, KICKR MOVE, and KICKR v4 (2018) and newer models.

The kit includes adapters for both drive‑side and non‑drive‑side installation, as well as additional parts to work with commonly used rear hub spacings. This helps maintain proper wheel alignment and spacing on the trainer and ensures stable engagement with the resistance unit under load. The adapters are precision‑machined to fit 12x142 mm and 12x148 mm thru‑axle standards, covering many road, gravel, and mountain bike rear hub widths. The kit also includes complimentary Shimano‑style and XDR‑style freehub locknuts to match a variety of compatible cassette bodies.

Installation involves removing the trainer’s existing end caps or adapters and fitting the appropriate thru‑axle adapter components before mounting the bike. Once installed, your thru‑axle bike should interface with the trainer as intended, helping reduce unwanted movement and improving ride feel during indoor training sessions.
