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.

I received the rack yesterday and took it on a 53 mile ride today. The rack worked out well: it did not rotate on the seat post, and it held the DX Trunk Bag perfectly. The Type E beam rack is the right size for a Specialized "medium" frame size; it should work as well on similarly sized frames from other manufacturers also. I have mine all the way down on the seat post, and there is ample clearance below the rack for the rear tire.

While attaching this to my bike and taking it on a test ride last night, I discovered that when my left leg was at rest, the quick release lever was rubbing the inside of my thigh. While pedaling it was fine, but I worried that if I made frequent stops, it would start chafing. I could feel the other side slightly as well. I tried raising the rack higher, but that made no difference--it just rubbed at a higher point. I moved my seat slightly forward, and that did not help much either. What I do now is point the quick release lever almost straight up. It is not ideal, but since I do not want a permanently installed rack, this will do fine for now. There must be some other way they could design this system so it might not rub so much.

I will admit, however, that after having taken it on a 53 mile ride, I never noticed the clamp, but I was also pedaling most of the time. During the ride, the rack never shifted once. I did not have the bag loaded too heavily, but the rack felt very secure.

Getting that quick release lever closed is a chore, especially the first couple of times you use it. The rubber shims needed to be "set" properly. What I did was put some light oil on the underside of the quick release lever where it hits the cap it tightens against, and that helps slightly.

Great high quality construction. Light yet strong. I use it to carry a full DXP trunk bag (i don't fold out the paniers). It solved the problem of not having a place to hook up a panier rack to my road bike- no connection points. Great thing about it is that you can take it off easily for weekend rides. Although not recommended, i use it on my carbon fiber seat post with no issues. Just be careful and get the right version. The selection of a downward, straight or upward angle version depends on the size of your bike and setup. Biggest thing to watch out for is that the CLAMP MIGHT RUB THE INNER THIGHS! Check the location in relation to the saddle. If your saddle if offset quite far back off the seat post (i.e. a lower more streamlined position) the clamp will touch your inner thigh when your leg is fully extended (particularly on the right hand side).
