The most important part of the Topeak story, however, is the passion of the founders and employees, who are cyclists, too. The company is dedicated to making the ride better, and focuses on creating products and accessories to help facilitate an escape from the traffic jams, cubicles, and mind-numbing meetings of everyday life.

Even when I got the clamp on tight enough.
I do own the Topeak MTX Trunk Bag EXP with panniers and this just completed the set.

The mount looks great and works great with the Topeak bags that are designed for it. I bought the side frames also because I got the EXP bag with panniers. The rack mounts pretty fast and easy to your seat post and the frame supports also go on pretty quick. I also put the MTX fender on, which I wasn't sure would go on with the pannier frame. It all integrates perfectly. I am going to post a picture soon. Make sure you put it on tight and realize it is really a commuter rack. If you are using it while hitting rough trails on a mountain bike expect it to shift around some if you have much loaded on it. As for frame selection I chose the A frame and it was an incorrect decision for me and so exchanged it for the V. I was afraid the V frame would sit too close to my tire with the fender on so I opted for a high set up. You should try to mount it low so as not to raise the center of gravity or battle the weight of the filled bag. The reason for the A frame is if your mounting it on a small bike with a low seat with little clearance from seat to tire. The equivalent of a BMX bike. The E frame should work for a lot to play it safe including road and mountain bikes. The V frame will work on quite a few as long as the tire isn't too big. I have a 26" mountain bike tire and it sits a few inches from the tire. Oh if you have a wedge under you seat you can probably keep it on but it is a tight fit. So far I love the look and other than one incident of it shifting have loved the performance.

This is the 3rd Topeak Beam Rack that I have owned. The other 2 have broken at the weld joints. The first two probably lasted a total of 3 years and about 6000 miles. You may ask, why do they break and why do I keep buying? Well, I think that they break because, while I use this rack on my commuter bike, my riding style may be better considered urban mountain biking. Riding up steps or down sets of stairs are common occurences and, in the end, I guess this riding style puts too much stress on the welds. I keep buying new racks because the Topeak pack that goes with the rack has held up well through this whole time and cost a significant chunk of change itself. The slide mechanism that holds the pack on the rack is absolutely fabulous. So, we'll see how long this 3rd one lasts. Next time I may go to a local steel shop and see if they can make something custom.

In summary, if you are going to use this on smooth terrain it is an excellent investment. The topeak pack/rack system works really well and the different packs available are remarkably verstatile. I have had no problems with the quick release mechanism, since once I put it on I rarely ever took it off. If you are going to be bouncing around alot, then it may be worth doing a little more research and evaluating other options. Ride On.

Purchased this rack with the MTX bag for our second bike, so now both my my husband and I both have one. We enjoy riding long distance charity road rides, and this set-up is perfect: take extra energy bars, ibuprofen, another T-shirt, or stash extra clothing. At home, my husband will make a run to the grocery store on his mountain bike, slip the bag off his rack, and pack it up in the store, slip it back on outside, and away he goes. It can be switched from bike to bike easily enough, and you looks nice enough that we've been asked where we got ours. Like I said, the fact that we're on our 2nd rack and bag should be proof enough that this is a winning combo.

I own a Topeak beam rack. I've used it exactly twice. I cannot fault Topeak's quality. They make quality products, and their customer service is fantastic. The problem I had with the rack is inherent to its design, in my opinion. Topeak chose to use a quick release. Good idea. Unfortunately, a QR doesn't close as tightly as a 4-bolt design---and I got really tired of my rack rotating when I took corners. I didn't overload it---I used the Topeak trunk rack and at most carried scrubs and lunch.

I now own bikes with rack eyelets. I have a traditional rack on one bike and that's ideal. But there is another option for bikes without eyelets----a saddlebag. No, not a SEATbag, but a traditional saddlebag, made by Carradice. They are not cheap, but they will last forever and can work on ANY bike, even the most flyweight of racers. If you use a Brooks saddle, attachment is easy---but there are adapters to work on any saddle. If I only had ONE bike and it had no eyelets, I'd just run a big saddlebag. Much more stable.

I got this rack more or less exclusively to carry one of the Topeak MTX trunks for bike commuting to work. There are several different styles of this rack with different angles.

Functionally speaking there is no difference in quality or utility between the different styles. The main difference is what angle do you need to attach to your seat post and clear your tire. The configuration of your frame, seat post and any other seat post accessories will determine which one is right for you. I got the straight post as that fit my bike the best (Cannondale Bad boy ultra).

I went for the clamp on style vs the screw on style because it gave me the flexibility to easily take it on and off. I can put it on for the commute and then when I get home take off and loose the extra weight for recreational riding. I can also easily move it to my mountain bike and use it for running errands and shopping. Keep in mind its weight limit is 30 lbs. If you are doing heavy shopping you need to get one that has struts that attach to your bike frame.

Getting it on and off is easy enough, just tighten or loosen the clamp screw. Its designed to fit thicker tubes. In order to get it on my old mountain bike I had to use a shim from an old rack of mine. It works fine, but keep that in mind if you've got a bike with a thinner seat post.
Once concern I had was if the rack was going to shift around a lot when loaded. I found that if I get it tightened right that's not an issue. It's held the weight of a watermelon and still not shifted. You do have to get it clamped down as much as possible. If you want the lever to fit flush you have to do the adjustments one full rotation at a time.

The rack has some rubber tie downs on it, haven't used them.
