Waterproof Bike Seat Bag by ROCKBROS, 3D Shell Saddle Bag for Mountain and Road Bikes - Cycling Seat Pack Under Seat Review

I was looking for a small bike backpack to replace my previous backpack which was small enough to only fit my phone (barely stretched) and keys or wallet and keys - but not all three. And I didn't want anything bulky. This backpack is very suitable for the purpose I need it for. the bike seat of my Giant Contend bike. It's easy to put on and the stiff sidewalls are a real plus.

I love how easy it is to get on and off the bike. I pack in extra hoses, carbon dioxide cartridges and my multi-tool. Unfortunately after all of this was packed while trail riding on my Trek Marlin 5 MTB, turbulence from the weight inside and trail riding made the zip pop open. I lost everything and had to buy back the hose, carbon dioxide cartridge, inflator and multi tool. I learned my lesson and now I'm pulling myself together. A small inconvenience for a good product.

Bought 2 of these in September 2019 for $18.99 each. Installed on 2 different bikes. One could not endure two short journeys on the towpath. The other traveled about 85 miles on the trail. The tow trail is smooth trail for the most part and none of these bags were loaded with anything loadable. The elastic strap that attaches the bag to the seat post ripped on both bags. I suggest you look for something more permanent. There were no problems with the bag itself, but now both are unusable.

The bag is not bad. It hangs for a very long time and supports all my flat gear repairs, and not just on the rides. I tie my bike to the back of my brother's jeep to get up the hill or to work and never have to worry about it. This is a good bag. I haven't had any problems with zips, velcro or waterproofing and I've ridden in bad weather. Good bag. I am the largest size. If you ride in a more upright position, consider sizing down as you might rub your feet a bit. The lower the saddle height…

Benefits: - Build quality looks solid - Fits snugly around saddle and seatpost without wobbling - Bag size is just right for a road bike. In other words, not too big and not too small - Looks nice - Bag is big enough to carry your essentials like inner tubes, spirit levels, tire sealant, tools etc - Nice strap to attach tail light - Reasonable price for that what you need Cons: No, I brought this bag to replace my previous one which was torn. This bag looks way better than my previous bag. I've

So far so good. No comparison with similarly expensive products. Pros: no wobble, 9/10 water resistance, plenty of room A small amount of water will leak through the pocket and zipper - no big deal, just apply some wax or waterproofing spray. It fits a multi-tool, a spare tube, other tools and a granola bar. Cons: Concerned about the silicone mount. Attaches the bottom bag to the seat post. Comes with an extra strap in case one breaks. Eventually it will likely oxidize and break down. Don't…

I bought this case to have a place to store my gear in case of an apartment. I can confirm - it fits the Vibrelli Presta & Schrader mini bike pump. It's JUST enough to fit in your pocket and close up. I also have a multi tool and some no glue patches. That is very high quality. The zippers seem strong and strong. I like the tail light band. If you are wondering, it doesn't fit iPhone 11 pro max. That's very bad. But that's not why I bought it. There are other cases from Rockbros that advertise…
