The #Silca "Super Secret" phrasing comes from our work with pro tour teams and developing products for them. The Mattone Seat Pack absolutely wasn't one of those products. But with the amount of pro's we see using them for training rides before grand tours it sure makes it feel like one. Why is that? Likely because the Mattone holds gear high and tight with the BOA mounting system, it has no wiggle or noise, so you can truly focus on the ride or training.
