Your basic dropout configuration with a derailleur hanger. Axle to derailleur distance is just shy of 30mm.

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 thru-axle dropouts. Vertical now, horizontal or thru-axle later. Options!

Vertical dropouts (with bolts) = 76g
Weight is based on representative samples. Actual weight may vary slightly. Imported.

The steel receivers are the foundation of this system. They are what you weld or braze into the frame.

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.

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.

We ship most of our packages Priority USPS with tracking. For orders with a shipping weight under a pound, we offer 1st Class Package shipping with tracking.

We send out packages M-F, except for federal holidays when USPS doesn't ship. If we receive your order before noon (Pacific time) M-F, it will likely go out that day.

We are now shipping to Canada! This is new for us and we're refining our automated system as we go. We will refund any excess shipping charges.

Packaging materials - With some exceptions, we only purchase paper packing materials. They're a renewable and recyclable resource and we like that. But we do reuse plastic/foam packaging material that we ourselves receive in our own orders.

If an item is damaged or has been sent in error, we will replace it and pay for return shipping if item is returned within 30 days of time of purchase. If you ordered the wrong item or changed your mind, you can return it within 30 days of time of purchase and be refunded the purchase price minus a 10% restocking fee.
