Customer Feedback

"I can't believe it took me this long to order tube blocks and hole saw arbors from PMW. I did not think it would change the game as many thousands of an inch as it has."

The best thing about Paragon is the dropout support for old and new emerging standards. Cant find that anywhere else.

@paragonmachine flat mount UDH dropouts made this build doable for me. Worth every penny.

These @paragonmachine UDH flat mount dropouts are my new favorite thing.

For the record, I absolutely love the conventional sliding dropouts you make! They never slip and are very tough, perfect for a bike that needs an adjustable dropout. I also think that they're beautiful.
