Question: what size handle bars does the clamp fit ? mine are 31.8
Document: The waterproof map holder on the top is fastened with velcro(tm) strips, so can be removed if you don't need it.But where it comes up short (and got docked one rating star) is the QuickClick Fixer 8 mounting bracket. More accurately, the screws supplied with the mounting bracket. The bracket has two clamps, designed to fit around 'oversized' handlebars, 31.8mm in diameter. Topeak supplies two pairs of shims, sized to fit smaller bars (nominally 28.6 & 25.4mm).
The fact that you can buy extra mounts for the bag is a huge, huge win because it means I can switch between my two bikes without dumping and re-filling bags.The mount, on the other hand, leaves me with two lingering concerns.The first issue is that while the specs for this mounting system for this bag (called &#34;Fixer 8&#34;) say it will fit 31.8mm diameter handlebars (the size I use) it was a very close thing - I ended up not using any of the shims provided and had to squeeze a bit to get the mounting bolts to thread.
The bracket clamps are fastened with two metric screws: M5 x 15 on the right side and M5 x 20 on the left side.I have a Trek bike, with 31.8mm Botranger bars. The M5x15 bolt is just a tad too short to catch the threads when fastening the right-side bracket. I tried applying &#34;gentle persuasion&#34; to the plastic clamp (squeezing it closed with a pair of pliers), but the bolt just wouldn't catch in the threaded boss that's embedded in the other half of the plastic clamp.
Haven't had much time to actually use this bag, but I really like its size. My biggest problem was with the mounting bracket. There are two hex head M5 bolts for mounting. the longer is a M5 20L and the shorter a M5 15L. My handlebar is 31.8mm in diameter so I had a very difficult time with the M5 15L being too short to close the bracket. After a struggle, I was able to get it to fit by removing the oval washer provided, but I'm not sure how that will wear on the plastic mount in the long run.
It is plastic but has held up. It uses a cable wrap under the bars to keep the bracket from sagging under load. The clamp screw for this cable never did work too well and finally failed when I removed and remounted the bag after about a year. It was fairly easy to fix with a longer bolt and a lock nut. The bag does not sag if you use a fourth hand tool to get the cable very tight when the bracket is installed.I will probably replace it with a Rando Bag mounted on a Nitto M12, or modify a handle bar bag to be mounted on the rack.
My wife and I were doing our first self-guided bicycle tour in New England. We needed a bag that would keep snacks, tire repair tools, maps, cell phone, etc for the trip. This mounts very well on the handlebars and was the perfect size to carry all the gear. I had to add a vinyl wrap to increase the diameter of my handlebars because the diameter of the handlebars was too small. Once I did that, the clamp holds the bag well and the quick-release allows you to take the bag with you if you need to if you leave your bike.
The Handlebar Bag Fixer 'A' that came with the bag  (quick release base) seems sturdy, but it features clamp arms that are way to small for the newer style handlebars on my '09 mtn bike. The bars are much thicker near the stem where the fixer is to be achoroed. Using longer bolts is not the answer as the clamp arms are at an angle and cannot be jointed. Bag itself is a tad smaller then I expected, but very well made and perfect for cams/phones and my 300 dollar lights.
I also tried removing the oval washer under the bolt head, but that didn't get enough extra length.The longer 20mm bolt works fine on the left-side clamp, and would also do the job on the right side. I called Topeak Customer Service to ask if they could send me another M5x20 bolt. That's all that's required - another 20mm bolt to use on the right-side clamp. They were unable to do so. Claimed they don't stock any spare parts. Reviewers here have been complaining about difficulties mounting the Fixer bracket on larger bars for ages.
I love this bag. Easy to put on and easy access while you ride. Perfect size for a handle bar bag.
I've been using this bag for a little over two months. I carry my wallet, cell phone, snack bars, bike tool kit, fix a flat can, rain jacket, lock, and assorted other items in it. I am frequently amazed at how much can fit into this bag. My favorite feature of the bag is its portability; it snaps off with the push of a button and becomes an over-the-shoulder bag.
Answer: yes
