This is a great system for building a versatile bike. Presto chango!

We also offer this system as a complete set. Buy a complete set and a pair of horizontal or vertical dropouts. Thru-axle now, horizontal or vertical later. Options!

The steel receivers are the foundation of this system. They are what you weld or braze into the frame. We only sell the dropouts as pairs so we can't sell you just a drive-side dropout with the hanger as a spare.

The aluminum dropouts bolt into the receiver (bolts included with complete sets and with dropouts).

The steel receivers are 20mm wide where the stays would be welded or brazed.

These thru-axle dropouts are 142/12 with 1.0 thread pitch. The 1.0 is compatible with some DT Swiss and others. There are many 142/12 thru-axle systems, but you have to know your thread pitch. Do your homework.

The thru-axle dropouts are supposed to work for 148 Boost, but there is a bit of an issue getting the axle length correct. So far the best solution is a 157mm x 12mm. Even that needs a bit of work since the threads bottom out. A spacer is needed to avoid that. We're working with the manufacturer to fix this.

Make sure you understand how these parts work together before you start welding or brazing. Measure 3 times, cut/weld/braze once. Figure out your disc tab placement early on too.
