Rob’s Road Disc Build

Rob’s Road Disc Build

Every bike has to start somewhere.  My bikes start with the tubes.  Rob is an incredibly strong rider and wanted a bike as stiff as possible.  He’ll be racing crits in Austrailia so I designed a custom, extra (extra) stiff tube set for his road disc bike.

Appleman Front triangle mitered in jig

The front triangle tubes are mitered and installed into the jig.

Appleman micro fillet

Micro fillets of adhesive are applied to the joints while the frame is in the fixture.  This provides sufficient strength to maintain alignment and remove the frame from the fixture for additional fillet material.

Appleman style brake bridge

Wisely, Rob elected to go with an Appleman style asymmetrical brake bridge!

 The tubes come together and finally look like a bike!  Adhesive fillets around the joints will give carbon fiber a smooth transition from one tube to another.

All of the carbon fiber has been applied and the frame has been sanded. Next step: high gloss clear coat!
