Tech editor Dave Rome recently visited the Handmade Bicycle Show Australia in Melbourne, where 3-D printing is playing a big part in setting a number of these builders apart from the rest of the world.

Also in this week’s show, we chat about upcoming developments in gravel bike suspension, whether CeramicSpeed’s Driven shaft-drive drivetrain really will see the light of day now that the company has an extra million bucks on hand and the likelihood that Ineos-Grenadiers riders might race at the Tour de France on clinchers.
