I came across the 2018 Specialized Diverge road bike. What is the little black piece attached to the downtube and seat tubes?

  • and I bet it costs a lot! I have my tools in a small triangle frame bag that hangs inside the main triangle straight behind the headset. Can even be accessed while riding. For me, weight-forward was more use than weight low.

It looks like a SWAT box (tube, co2, levers and multitool) see https://www.cyclingabout.com/2018-specialized-diverge-light-touring-bikes https://www.topvelo.fr/documents/Image/specialized-diverge-2018-12.jpg from https://www.topvelo.fr/actualite-materiel-velo-nouveau-specialized-diverge-serieusement-rapide-serieusement-fun-3-993.html

  • Spot on. Specialized make them for a few of their road bikes
