Key Details

Detail Product information and buyer relevance
Capacity 0.8 L. Compare the available space with the size and shape of the items you plan to carry.
Attachment A rotary-dial mechanism is described for fastening around the seat rails. Check that it fits your saddle setup and available rail space.
Storage layout Separate interior compartments and a wide-opening main compartment are described for organizing and viewing stored items.
Color and model Black Grid; model 30130091002-ALPSUS.
Moisture protection The material is described as water-repellent for light rain and road spray. This does not establish that the complete bag is waterproof.

What to Compare Before Buying

  • Mounting fit: Check the rotary-dial attachment against your saddle and seat-rail arrangement. Specific fit dimensions or compatible bike models are not provided.
  • Usable space: The capacity is 0.8 L. Consider whether the bag can accommodate your intended items, including their shape and how you want to organize them.
  • Wet-weather needs: The stated protection is for light rain and road spray, not waterproof protection for the complete bag. Consider how to protect moisture-sensitive contents in heavier or prolonged exposure.

Before You Decide

Confirm that the attachment suits your saddle rails and that 0.8 L is enough for your intended contents. Treat the stated water repellency as limited to light rain and road spray.
