ROCKBROS 12L-20L Handlebar Bag with Two Dry Packs Review
This set is the most volume on the bars for the money: a 14 to 15 litre roll-top bag plus a front pouch. It straps directly to the bars, and keeping it there is the work.
The verdictPlenty of dry volume for little money, and owners report it stays dry. The strapping is the weak point, so tie off every end.
The Amazon US listing, sold by ROCKBROS LLC and shipped by Amazon at $74.99 on 7 October 2026, is a set of two bags in 600D nylon with TPU. The roll-top dry bag holds 14 to 15 litres at 538 g and 85 x 29.5 x 20 cm unrolled, and the pouch that straps to its front holds 5 to 6 litres at 180 g. ROCKBROS advises at least 40 cm between the drops, and either bag doubles as a waist bag off the bike.
There is no harness. The roll straps straight to the bars with a head-tube strap and spacer cushions, according to owners, and that is where the complaints sit. Owners describe the bags drooping onto the tyre, the head-tube strap slipping, straps with no keeper that can reach the wheel, and a sideways slide that crushed a cable housing.
The listing calls the fabric water-repellent in its bullets and waterproof in its details table, but the owner record on water is strong. Amazon's review summary counted no negative mentions of water resistance, and owners describe a 3,000 km tour without leaks and trips through Japan and along the GAP and C&O. Durability mentions are split, and the straps need re-tightening during rides, by Amazon's summary.
Owners on Amazon US gave it 4.3 stars from 252 ratings in October 2026, with 10 percent at one or two stars, on reviews going back to 2018. The listing's spec table gives a weight and colour that contradict its own description and photos, so trust the bag weights above. Tidy and tie off every strap end before riding.

What doesn't
