This week’s Nerd Alert episode takes a closer look at two recent events in this year’s Tour de France.

In stage 1, Jumbo-Visma rider Steven Kruijswijk finished the stage missing an entire seatstay from his prototype Cervelo, and in stage 5, EF Education-Nippo riders tackled the stage 5 individual time trial on a new Cannondale TT bike.

We chat with Cervelo to find out how that bike could have possibly survived — and apparently without Kruijswijk even knowing! — and get some tantalizing tech details from Cannondale on that new bike before its official release. Sorry, folks, this one’s pretty long, but we promise it’ll be worth your time.
