Paragon Machine Works post mount sliding dropout DR4025 Paragon Machine Works post mount rocker dropout DR4026

Paragon Machine Works is now offering two new dropouts for use with their titanium and steel flat or flanged dropouts.

The new designs are direct replacements for their ISO disc brake mount dropouts and only replace the left (non-drive) side. Aimed at frame builders, they’re available in quantities of 50+ only and should be a welcome addition to custom builders looking to simplify the complete bike build and drop a few grams. The post mount is designed around a 160mm rotor. The ISO and other options will remain in the catalogue.


  1. I think you saw that there are more than 50 units currently available for online purchase. You may want to check with them on that: they have bulk deals for less than 50 units. I believe you can order individual ones for the listed price and bulk orders receive a discount.

  2. Yeah, the statement, “they’re available in quantities of 50+ only”, is incorrect. Anyone can go to their website and order a single unit if they choose…just use the drop down menu in the shopping cart area. In fact, I did this just the other day and it’s scheduled to be delivered tomorrow.
