While the increase in the size of the seat roll might have been an obvious solution, we couldn't just stop at the obvious.
We started this project with a test group of riders from various cycling disciplines and had them ride more than a dozen Grande Americano prototypes for more than 10 months. The primary focus of this group was to identify potential areas for improvement and opportunities to innovate. Our focus group consisted of gravel and mountain riders who require more space for larger tubes, and a few road riders who wanted the ability to carry multiple inner tubes.
The result of this test led to a few unique updates to the original design. For starters, we moved the BOA System down to the lower third of the roll which helps keep the roll secure over the roughest surfaces while also keeping the bag 'high and tight' under the saddle so it doesn't rub your shorts. Next our designer created a unique Lower Pleat in the bottom of the roll which gives it the unique ability to expand when loaded while laying flat when unloaded.
Lastly, we increased the strength and tension of the vertical axis strap to better support the load and ensure total silence and solidity over even the roughest surfaces. These refinements, along with the overall increase in size make Grande Americano an extremely capable seat roll; and one that you can use with virtually any bike.
