Geek Warning: Chains that rust too easily

Have you experienced certain models of Shimano 12-speed chains rusting more easily than expected? It’s one of many topics in this week’s Geek Warning, the cycling tech podcast from Escape Collective.

This week, Suvi, Alex, and Dave also discuss limitations and concerns regarding the fast-arriving 32in wheels. There’s talk of new bikes. And what we carry for fixing tubeless punctures.

Those on our member-only feeds also get access to Ask a Wrench, where this week Colorado-based pro mechanic Colin Williams joins Dave for the first time.

Happy geeking!
