Features

It utilizes a durable abrasion-resistant construction of Waterproof PVC backed 420D ripstop nylon which is seam-sealed. It features a roll-top quick-release Duraflex buckle closure design that protects the contents from water and debris. Although not waterproof, the material, seams, and roll-top design mean the bag is extremely water and weather resistant.

For attachment to the frame, saddle or their B-RAD mounting plate, it utilizes a 2″ wide Velcro hook-and-loop fastener strap with a sticky silicone strip backing. The grippy silicone goes against the frame to securely hold in it in place, while the Velcro lets you lock it down tightly to prevent an errant movement. It has two slots on the back of the body for the straps attachment, so you can insert it into either one depending on where you mount the bag.

Impressions

Although you can put almost any small gear into the bag, I used it for my spare tube, and tire and chain repair tools. With its 0.6-liter capacity, it offers plenty of storage space for a small bag, and you could carry a phone, wallet, snacks, and other items in the compartment.

You do want turn over the roll-top at least once before closing the buckle to protect the contents from water and debris. I was able to roll it over twice when I filled it with all of my repair gear, making for a nice snug bag. Even though it’s not entirely waterproof, I never found that any my gear ever got damp or wet, even in torrential summer downpours, so it was pretty water-resistant during my usage. I did find some rare pieces of dirt or sand would sneak there way inside, but it was extremely minimal.

None of my gear is overly sharp, and even though I was careful of where I placed metal tools, I never had any wear and tear issues. The rugged material and mild padding helped greatly for protection, but you might need to be mindful of hard objects, especially when using the bag on the metal B-RAD mounting plate and saddle rails.

Once the gear is placed in the bag, and the roll-top is turned over, and the buckle is snapped shut, you can put it wherever you want on the bike. On my Ibis RipMo, the perfect location was in the shoved up in the corner of the front triangle by the head tube, resting on the upper shock mounts brace.

To attach the bag, wrap the straps grippy silicone-backed side against the frame, insert the tail of the strap through its buckle and pull it back against itself and secure the hook-and-loop to lock it tightly in place. The 2-inch wide strap provides a lot of holding power, leverage, and security when attaching the bag, and it was easy to adjust or remove, even with cold, wet fingers. The hook and loop strap system allows you to quickly remove the bag once you reach your destination or your done riding for the day. The strap was long enough that it fits just fine around my fairly massive carbon tubes on my RipMo.

With the bag wedged into the upper triangle, and lightly resting on the rear shock brace, and snugged tightly down with the strap, it rarely ever moved out of place. The bag has a thin profile, so it offered a streamlined fit on the frame. As long as it was in its proper position, my knees never hit it while pedaling.

I like that you can use the functional Mini Roll-Top as stand-alone on the frame tubes, saddle rails, or the B-RAD mounting system.

If you get the full kit, it consists of the bag, strap, B-RAD system mounting plate and hardware. This allows you to install the B-RAD plate to the B-RAD base (not included), which offers the ultimate in an organized, secure on-bike storage system.

The B-RAD system begins with a series of slotted Mounting Bases that are available in three sizes, B-RAD 2, B-RAD 3, B-RAD 4. The B-RAD bases can shift a bottle cage away from inconvenient rear shocks, add room for tools or tubes below a bottle cage, or even provide space for a second bottle on sufficiently-long downtubes. Next, you can mount various B-RAD accessories to your B-RAD base or bases. The B-RAD accessories improve or optimize bottle cage locations, add water/tool/spare parts capacity.

Bottom Line

The Mini Roll-Top Bag is a light, compact, streamlined, and flexible storage system for your bike, and can be mounted on the frames tubes, under a saddle, or to their B-RAD system. The 0.6-liter capacity can carry items such as snacks, spare tubes, and tools, keeping the gear secure and protected from the elements. The beefy 2-inch wide Velcro strap with its grippy silicone strips keeps the bag securely attached to its location, and it’s length fits oversized carbon tubes. The well-made bag is robust, water-resistant, and hasn’t shown any overt signs of wear and tear during prolonged use in heavy use.
