The full crew is finally reunited for this week’s Nerd Alert podcast! Now that Shimano’s new 12-speed Dura-Ace Di2 groupset has made an appearance in the wild, we dive into what we can confirm (it’s black), what we think (wiredless?), and what we hope to see (a mechanical version in polished silver!!) in the company’s new flagship road components.

We then debate the pros and cons of hookless road wheels, the idea of a flat-proof tube, and finish with an extended Ask a Mechanic segment with questions fielded exclusively from our Veloclub members — and Zach mostly kept his promise to not be too salty this time around.
