Geek Warning: Shimano GRX going 12, and a flurry of new bikes

There is so much new stuff to talk about this week! Unbound Gravel was a smorgasbord of fresh gravel good, including new bikes from Canyon and Santa Cruz, and a sneak preview of Shimano’s new 12-speed GRX groupset. We’ve also recently spotted new road bikes from BMC and Factor, and Silca aims to make chain waxing (a lot!) easier. And speaking of Unbound, what was the true material cost of entry for this year’s event? Hint: It's almost certainly much, much more than most participants expected.
