Needs more Velcro and stitching

  • Familiarity: I've put it through the wringer

Overall I have been very satisfied with the bag, but just as others have said there needs to be slightly more Velcro on the strips that attach the bag to your saddle. It makes it difficult to get the bag tight to your seat while having enough Velcro overlap so that you are not scared of losing it. I also had the strap that attaches the bag to the seatpost tear off during a ride the other day. So maybe not the best bag to use on a mountain bike.

Can't stabilize the bag

  • Familiarity: I returned this product before using it

This bag is extremely well made, but just as other reviewers said there isn't enough velcro to secure the bag! This leaves it to sway side to side - a deal breaker for me! Seems like a flaw in the design. Returning it. Too bad, because I did like it. BTW Competitive Cyclist I will be going to other vendors from here on out. Not only do you charge to ship, you charge to return - pretty much leaving me with a very small credit. Not great service.

Nice bag

    Got one for each bike. Perfect size for a tube and repair tools. Looks good and stays put.

    Seat bag

      I bought 2 of these they are the perfect size for an extra tube and tools to change a flat with room for car keys. They look good too, It has a little strap on the back I clip my garage door opener to when I ride from the house.

      Works as Advertised

      • Familiarity: I've put it through the wringer

      Attachment mechanism is not perfect but works 100% good enough for my daily commuter. Bag seems well built and durable.

      Good size

      • Familiarity: I've put it through the wringer

      This is a nice bag with good volume. It's carried everything I've needed to bring along on my rides.

      Nice Size, Durable

      • Familiarity: I've put it through the wringer

      The bag is a great size. I can fit a tube, tools, inflator, inhaler, and keys all in it. It has a semi-rigid plastic in the top of the back which stops the seat post wearing through the bag. My only complaint is that the Velcro strap seems to long for the bag, so I have a lot of excess strap and only half of the Velcro is engaged. This has not been a problem yet; it just looks a bit goofy.

      good size

        ordered the medium and its a solid size, hooked up to my dropper post just fine, big enough fro my phone, an energy bar and key plus a patch kit and co2

        Just What I Needed

          This bag fits securely and is nicely sized and doesn't protrude out. It also fits all the necessities for a quick repair(multitool, pump, tube, levers and patches) and even my wallet. Just what I needed, I would highly recommend this product.

          It works and stays on.

          • Familiarity: I've put it through the wringer

          Nothing to complain about. The small can hold my road tube, inflator, co2, levers with room for keys and a bar. It stays put and looks great, and the zippers don't snag. What more could you ask for?


          • Familiarity: I've used it once or twice and have initial impressions

          Just right for the repair kit, tube and snack.

          2 Tubes! Score

          • Familiarity: I've used it several times

          Had trouble locating a bag that would hold 2 tubes but not be enormous. I bought the medium size of this bag.
          This looks good, fits well, holds what I want it to, and seems like it will last.
          Could be a bit more secure as the Velcro isn't lined up well enough to really crank down on it but it wont fall off.
          Fit 2 road tubes, 2 tire levers, multi-tool, pressure gauge, backup battery for headlight, and some meds.

          2 Tubes! Score

          Update almost a year later:
          Still like the size and ease of use. Blackburn products have a lifetime warranty - I had the bag replaced because the zipper failed. You could say I overstuffed it that day, or you could say overstuffing is part of the life of a seat bag.
          *Not* sturdy enough for off-road! I recently started doing gravel rides and the velcro strap for the seat post tore off the body of the bag. Had the bag warrantied again; the velcro tore off from the new bag on the first gravel ride! Will keep my next replacement as road only :)
          Blackburn customer service is fantastic. Although you may need to ship them the failed part or email them pictures, the shipment on the replacement is super fast - and you actually get to talk to a person on the phone!

          Good but not great

          • Familiarity: I've used it several times

          A nice-sized MTB bag for today's larger tubes; however, I have two quibbles. First, the inside of the flap does not have a little pocket, which is always nice for CO2 inflator heads and power links. Secondly, the straps are much longer than they need to be, preventing me from cinching it up as tightly as it should be. When I pull it very tight, I run out of Velcro. Thus, mine hangs a little loose and sways around a bit even when it is stuffed to the max.

          Unanswered Question

          What are the dimensions (not capacity) of the medium sized bag?

          Great bag

          • Familiarity: I've used it several times

          Holds two mountain bike tubes plus patch kit, multi-tool and emergency nutrition without having an in-your-face logo like other bags. Reflective piping is nice and my tail light clips over the logo.
