What Our Gearhead(R) Experts Are Saying: "I like this bin-bag for heavier grocery runs and awkward loads that don't fit well in panniers. It stays upright on the rack, rides quietly, and folds down flat when I'm not using it."Big errands and unpredictable loads call for a cargo setup that doesn't flinch. The Chasm 25L Cargo Bin steps in as a reliable way to carry groceries, gear, and oversized items without overthinking the load. Thule gives this bin a clean, utilitarian design that feels equally at home on weekday errands or weekend rides. A structured frame helps the bin hold its shape when loaded, while a reinforced base prevents sagging under heavier cargo. When the ride is done, the bin collapses flat for easy storage. Compatibility with the InLock system keeps mounting simple and rattle-free, making this a practical choice for riders who regularly ask more from their bike.
