On the topic of changing, non-standard “standards” in the bicycle industry, we share consumer frustration with the wasteful and short-sighted practices of proprietary dimensions, limited functionality, and planned obsolescence that large component companies engage in.

The existence of multiple front axle dimensions has been one of those frustrations. For using 15TA front hubs/wheels with 12TA forks, the PDXTI-12-15-TA Adapter provides a simple, inexpensive, and lightweight solution. Going the other direction — using 12TA wheels with a 15TA fork — is however not as simple.

Thankfully, we are now able to offer a solution for cyclists with one of the many titanium and steel forks that have been built with Paragon DR0049 titanium or DR2051 steel and similar 15TA front flanged/hooded dropouts with threaded axle inserts.

Developed in collaboration with PDXTI and now available in the web store, these threaded fork dropout inserts convert titanium and steel forks with the aforementioned 15TA dropouts into 12TA forks.

At its base this product consists of a pair of externally threaded left hand M22 x 1 inserts, one with a 12mm thru hole and the other internally threaded M12 x 1.5 for 12mm Thru Axles.

Available as inserts only, with traditional QR lever axle, or with lightweight @robertaxleproject thru bolt.

Inserts Only: 22g

Inserts + Bolt-On Axle: 51g
