This is a sneak preview of our new Nerd Alert podcast, so if you like what you hear, make sure to subscribe on your favorite podcast platform. 

Although we’ve done all-tech podcasts in the past, the new Nerd Alert will now come to you on a more regular basis — every other week — and will be co-hosted by global tech editor James Huang, Australian tech editor Dave Rome, editor-in-chief Caley Fretz, and professional mechanic Zach Edwards, who owns and operates Boulder Grupetto in Boulder, Colorado.

For this initial episode, we discuss in detail the key findings in Dave’s most recent tech feature, which dives into Adam Kerin’s incredibly exhaustive research on chain efficiency and durability. Which chains last the longest, and which ones aren’t worth the extra money? What’s the most economical way to keep your expensive drivetrain running smoothly? And what are our hosts’ favorite chain lubes?
