Cycling Weekly Verdict

The smallest of Miss Grape's seat post bags, named Cluster, this totally waterproof 7 litre bag functions best as a day bag for tools and spare layers rather than part of a bikepacking set up. The small size and single strap mean that it's a great option for riders that have shorter seat posts and can't fit larger bags.
