Wolf Tooth Wolf Axle Trainer Caps

Wolf Tooth Wolf Axle Trainer Caps Info

The Wolf Tooth Wolf Axle Trainer Caps are a simple, well-executed solution for riders who want to move seamlessly from outdoor riding to indoor training without unnecessary hassle. Designed specifically for Wolf Tooth rear axles, these caps allow thru-axle bikes to be used with most wind, magnetic, or fluid trainers—making winter workouts and weekday sessions far easier to commit to.

Wolf Tooth’s approach focuses on convenience and durability. The non-drive-side axle cap pairs with a drive-side plug that installs and removes without tools, eliminating the usual frustration of swapping hardware every time the bike goes on or off the trainer. It’s a small detail, but one that makes a big difference when motivation is already tested by cold weather or limited daylight.

CNC-machined from 6061-T6 aluminum and weighing just 12 grams, the Wolf Axle Trainer Caps add virtually no bulk while maintaining the same thoughtful fit and finish Wolf Tooth is known for. For riders already using Wolf Tooth axles, these caps are a clean, purpose-built accessory that keeps indoor training quick, repeatable, and frustration-free.
