Pitlock Locking Thru Axles

In recent years, thru axles have established themselves as the dominant standard for mountain bikes, and are increasingly becoming relevant in other categories as well. This is especially true for higher-end models, where the thicker axle provides precision steering and increased stiffness. However, there are still very few standards between through-axle manufacturers, and determining the size you need may be intimidating if you are unfamiliar with the construction of your bike. Please contact us if you have any sizing questions. Below are the Pitlock thru axles we have available for sale, which align with the sizing specifications outlined in this table:
