Adjustable Dropouts

General Information

Our adjustable dropouts allow for different brake and derailleur configurations through the use of right and left-replaceable inserts. Consider the following when you select your frame component:

1) Aesthetics

2) Frame application

3) Weight of rider

4) Any other features that are important to you or your frame builder, i.e., the option to mount racks, use a belt drive system, etc.

• Function as a modular dropout and allow for changes or updates to an existing frame
• Allow for simultaneous chain tensioning and proper positioning of the brake caliper
• Have enough range for all common applications

Preventing Slippage

• Verify that your frame components and inserts are made by Paragon Machine Works; we cannot guarantee compatibility with products that are not made by us.  Note:  this is the number one reason why inserts slip!

• Verify that the contact surfaces between the frame components and inserts are free of contaminants such as paint, dirt, grease, etc.; there must be metal to metal contact ONLY.

If you have verified the above and your inserts are still slipping, then we recommend:

• Upgrading to titanium screws

• Applying medium strength Loctite® Threadlocker Blue 242 to the screw threads:

  • Cures when confined in the absence of air between close fitting metal surfaces

Important!

• Compatibility between components is only guaranteed when using parts made by Paragon Machine Works.

• We cannot advise or make recommendations for parts made by other manufacturers.

General Information

1) Always use our 304 stainless steel washers with the screw

• Helps to spread the load over a larger area
• Hold the parts together better
• Keeps your frame from getting damaged from repeated tightening/loosening of the screws

2) Titanium screws offer the following advantages over our stock steel button head cap screw:

• The hexagon is deeper and manufactured to a closer tolerance
• Lighter
• Aesthetically pleasing
• Can be torqued 10% more than our steel bolt (see below)

Torque Specs

• 24 to 26 N-m

• 2.4 to 2.6 Kg-m
