    This is a great saddle bag! It fits snug and there is no sway when I ride. Plenty of room for a spare tube, adapter, tire levers and a small multi-tool device. And it’s water resistant to keep everything inside dry.

    This expands to suit extra tubes.

    bonito y facil de instalar, no creo que contenga una lluvia, el cierre trae una parte que no sella con el “impermeable”

    The bag was easy to install, uses velcro straps to attach to your bike so easy to take off if needed. Enough space to hold some snacks, keys, wallet, and a few bike tools. It will expand but haven’t needed that feature yet.

    Durable case for underwear that doesn’t extend past the rear of seat. A bit smaller than some so know how much you need to carry. Attached easily.

    I’ve had numerous name brand under seat bags durring my cycling life. This is as nice as any of those. It’s big enough to hold a larger capacity innertube (for adventure bike), CO2 inflater, and tools, without looking rediculous. The expansion zipper is a nice touch. Velcro attachements work consistently well. Half the price of the bike shop equivalent, but every bit as nice.

    Fits up tight to seat leaving no spaces like many others do. Shape makes it look more form fitting, even more aero friendly while still having plenty of room. I have a spare tire, co2 canister and pump, a plug tool/kit, multi tool and still have room for my wallet and a couple small items like an apple tag. That is without using the expansion zipper. Also love how cover unzips and folds down without everything falling out (like Topeak) and is open enough to actually see what is in the pack (opposite of Topeak).

    This review is for ROCKBROS Bike Saddle Bag, Bike Bag Under Seat, Strap-on Cycling Wedge Pack, Bike Seat Storage Bag for Mountain Road Bikes, 0.75L.

    It was a bit larger than I was expecting, It sticks out past the end of my saddle by a couple inches.
    I’m pretty happy with it. I stuck a 700c spare inner tube, 3 tire levers, a multi tool, a
    CYCPLUS Tiny Cube Bike Pump, an inner-tube patch kit, and my little wallet (kind of like ridge wallet) in there without even needing to open the expandable zipper area. I could probably cram a granola bar in there too, but it was pretty full with those items.

    one thing that seems a little strange is how long the velcro strap that goes around the seatpost is. I guess they made it that long for those REALLY aero shaped seat posts.

    It is well made, looks solid, but it is quite small, even with the totally unnecessary extra zipper that makes it a bit wider when opened. You can just put in one spare tube, the repair kit and your keys. That is about it, the smart phone does not fit, even if I put nothing else in. The saddle bag is too short for a standard Galaxy! Rockbros, make it about 30% bigger and it will be a good product!

    I was looking for a small underseat bike bag and Topeak has always been my go to. Unable to find the small Topeak bag anywhere. Plenty of the micro small and larger bags available but no just small. Found this redesigned Rock Bros small underseat bag at a much lower price than Topeak. Fit and finish rival Topeak. Looks and functions great on my road bike

    This Rock Bros seat bag was purchased for a ‘ flat tire bag’ for my ebike, and works flawlessly. The straps that fasten it to the seat rails are leather and pliable, and fasten securely with velcro. The bag is water proof, with a waterproof zipper. A rare feature I haven’t seen on other seat bags is the zipper running down the bottom side that allows the bag to expand quite a bit when unzipped, allowing a little more valuable storage space. With the zipper closed, in this bag I keep a new 27.5″ x3.0 tube, 2 Large sized compressed air cylinders, a valve for those cylinders, and 2 break-down levers.All neatly stored beneath the seat and easily accessible. Rock Bros. makes good quality bike accessories, and this bag is no exception.
