Wolf Tooth Components B-RAD Roll-Top Bag (Bag and Strap)

Have been using a WolfTooth B-RAD 4 to relocate my saddle bag for about two years now, using a generic bag that fits between the water bottle cages. Saw this waterproof bag and decided to give it a try— good thing, too, as it rained on my pretty heavily the day after I mounted it to the bike.It absolutely performs as advertised. Holds so much I have empty space in there, and is 100% waterproof— I used to have to empty the old bag, lay out the contents to dry, and put the bag on the rack in the dryer with my soaked shoes. The Roll-Top Dry bag stayed, well, dry. As usual, the excellent construction I’ve come to expect from WolfTooth.

This is a nice secure bag. I have several CO2 cartridges, tire levers, and a tubeless repair kit inside it. These were previously rattling around in my backpack making tons of noise, but this acts like a compression sack and don't let any of the stuff inside move. The quick release buckle is easy to use, no zippers to get jammed or velcro to wear out into a fuzzy mess, and the bag is big enough to allow me to reach in and grab what I need. The rubbery material on the band keeps it from slipping on the bike frame.I don't have this installed with the B-RAD system, so I can't comment on that, but as a nice compact storage bag you can put just about anywhere, it's very nice.

Many newer mountain bikes can't accept anything other than a Blackburn Grid Saddle Bag which will hold about 4 decks of cards. I needed more space for my Yeti SB130 and this bag did the trick. It can be mounted nearly anywhere but I put it on top of the top tube and clipped the roller top around the handlebar riser. It holds in place nicely and is out of the way for normal riding. There isn't enough room in the new Yeti design to fit under the top tube without running into the shock. Full dimensions are about 8.5"Lx4"Wx3"H. Also high quality construction.

This bag is awesome. It’s large enough to fit everything I need plus there is a lot of room left. I will admit that I was worried when I first saw it. But I have a tube, first aid supplies, tire levers, patch kit, cO2 inflator, cO2 canisters, and a multi tool in there. I bought this since I had just installed a dropper and wanted something that would work on multiple places on my bike. I decided to still have it mount under the seat and it’s awesome. It looks great and is very capable.

Works awesomely. A bit expensive. Great way to securely hold gear with no annoyance of mud/dirt/grime getting all over your tubes/levers/tools.

Nice solution to saving space. Great for enduro and long trips. The rubber ribs keep it in place (if installed properly) and it will fit a tire pump, not a fork pump.

Great bag. Fits my enduro 29er percectly in the triangle. No need for my pack for 2 to 3 hr rides. Can fit all i need from spare parts to tools.

Well made and a surprising amount of room for storage. I have a tube, multi tool, two CO2 cartridges, and tire levers in it and it's only about 2/3 full.
