Know before you buy
The Banjo Brothers Large Seat Bag uses a universal mounting system that attaches to both the saddle rails and the seat post. It is designed to be compatible with the vast majority of standard bicycle saddles.
With a 2.13-liter capacity, this bag is spacious enough to hold a standard repair kit—including a spare tube, tire levers, and a multi-tool—along with extra room for essentials like a wallet, snacks, or a lightweight windbreaker.
Yes, it is constructed from 840-denier nylon, which is a heavy-duty fabric designed to withstand the wear and tear of daily use and rugged riding conditions.
Absolutely. The bag features an integrated rear tab specifically designed to accommodate most standard blinkie safety lights, helping you stay visible during low-light rides.
The bag includes a dedicated zipper system that allows you to increase the main compartment's volume. You can keep it compact for shorter rides or expand it fully when you need extra space for longer trips.
While the 840-denier nylon is highly durable and water-resistant, the bag is not fully waterproof. It will protect your gear from road spray and light rain, but we recommend using a dry bag or plastic sleeve for sensitive electronics in heavy downpours.
