Designed for the tough world of mountain biking. The MTX is great for mountain bike touring with a full-suspension rig. It features a new universal deck design for mounting any one of our QuickTrack Trunk Bags.
Strengths: Strong and simple to use, well priced, does exactly what is needed of it.
At first the rack would sway a little, but really cranking the bolt with the provided shims soon fixed that. Similarly the quick release would rub my inside thigh, again simply setting the quick release lever to th3 2 o' clock position remedied that problem. I use the bar with the matching bag (with zip out side bags) and commute over 250km a week with about 10kg of load, it is excellent and at the price a real bargain. Before I bought this I was using a great tatonka X-vent backpack, but having the load off my back makes commuting so much more pleasurable.
Bike Setup: BeOne Karma 2.0 w/ Easton HAVOC AM wheelset.

Strengths: It works! I got it on closeout with the bag that slides into it for $50 2 years ago. Does exactly what it's supposed to.
Weaknesses: I use it on a cross bike. Read: short exposed seat post. So, it rides a little high on this bike. Not a problem on my compact frame mtn. bike. That high on the bike, and your center of gravity is a little wacky for a while, and the big-ass clamp rubs your legs until you get used to it... Lose the quick release.
Replace the quick release right away with a bolt and a washer, and crank it down. 1. It's going to slow someone down from taking it. Commuters can't use quick release anything unless you want to carry it everywhere. 2. My rack does not move a fraction of an inch under daily use, 8 miles a day, five days a week, packed to at least 20 pounds.
No more sweaty back from a backpack when I get to work! (If only my laptop fit in the thing!)
The rack intially swayed under load despite using the supplied shims (crap0, Eventually cut up an old tyre tube and used that. I have since had no movement despite the load I place on it (to it's maximum) and the maniacal riding I do through the city streets. Obviously this is not a rack for off road; buy one which attaches to more than just the seat post for that purpose. Otherwise, it's a good rack for when you want a rack for small things or for commuting with a light load and it's convenient in that it can be removed easily enough.

Strengths: Ease of use; light but surprisingly strong.
Just completed a ten day crossing of France's "Massif Central" with this rack on the back of my hardtail. Initially the quick release would allow the rack to sway one way or the other (especially on fast,rocky/technical sections). The easy fix was adding a rubber shim (inner tube), between the seatpost and QR clamp.
Gave it a good beating and was very impressed with the overall sturdiness and strength of the set-up.
Strengths: Simple, clean lines, except for jagged edge where it sheared in two. Makes interesting conversation piece (or more specifically, conversation PIECES.)
Weaknesses: Weakness is right! It broke in normal usage. Customer service was non-existent.
This rack failed from metal fatigue, breaking close to the clamp which holds the rack to the seatpost. I guess it couldn't take the cantilever loading of 5 pounds on my occasional commute along two miles of smooth roads. I would anticipate I put less than 300 miles on that rack.
I emailed Topeak twice to see if they would address this failure. They did not respond, which has caused me to stop buying their products.
I can not recommend this product, but if you insist on buying it, you should only plan to carry a load occasionally, not daily. This is not a rack for commuters.
Also: if you must buy this product, don't mail-order it. It'll be a lot easier to get a refund/credit from your local bike shop than from a mail order house when it breaks. (Don't even bother contacting Topeak for a refund.)
To be fair, all seatpost-mounted racks will probably suffer from this type of fatigue. However, they could have designed it with more beef where it counts. Maybe I got an earlier version and the new ones are better. I wouldn't know because Topeak never responded (or did I mention that already?) >=|

Strengths: No eyelets? No problem!
I bought this thing four years ago and gave up on using it. Like so many previous reviews, this sucker sways back and forth no matter how hard you tighten it. For that reason alone, I can't recommend it.
This rack works great for daily bike commuting, which is grueling duty cuz the miles really add up. When I first got this thing, it broke in half within a couple of months. Topeak replaced it with no problem, and sent a redesigned model that was obviously much stronger. The replacement has lasted a year and a half. I cut up a rubber jar opener (you know, the rubber disk you buy at the supermarket) for shim material, and that works fine. I don't have any accessories, I put my clothes, towel, keys, tube/pump/multi-tool, cell phone, lunch, books sometimes and whatever else in a small duffel and strap it on with two bungies. That gives you an idea of the weight, maybe 10-12 lbs. It's great, if you need it, get it.

Strengths: Easy to take on and off, fairly large, sturdy build, matching bag system
Weaknesses: easy to steal if it is not locked to the bike
This rack is very nice. I have the new MTX version. This one is the biggest QR rack they make. I think I figured out how to solve the shim/rotation problem. I cut the shim a little off center and Krazy glued the pieces onto the inside of the clamp. It works great.
I was dissapointed that Topeak is not making the baskets for the new racks. My intention was to get the basket to carry my briefcase in around campus because I thought tossing it into a basket and throwing the bungee net (that Delta makes) over it would be a lot faster than securing the bag directly to the rack. However, I went to the container store and found a basket that will fit my briefcase better anyway. I am hoping that topeak would be willing to send the piece that slides into the rack (though they probably won't), but for now the basket is easily secured to the QR rack with some velcro straps.
Overall, a very nice rack, and not too awful of an expense.

Strengths: Easy on, easy off. Lightweight. I don't have the Topeak bag to fit onto it, but it seems like it's a good feature if I did. Can be used on a dual-suspension.
Weaknesses: Can't hold as much weight as conventional bike racks. rubber bungee that is provided is virtually useless.
It is a decent rack. I like the ability to quickly install and remove it with the quick release lever. Like I stated above, I don't have the correct bag to go with it, but it hold other bags well enough--just provide your own bungee cord or strap, because the one provided is useless (unless I'm just too dumb to figure out how it works). I haven't had any trouble with keeping the rack in place as others have according to their reviews. I don't understand their complaint about a pump holder either, as there are two bolts underneath to attach a water bottle cage or pump holder that comes with your pump. Anyway, a good rack, and not too expensive if I remember.

Strengths: Very well made, good vfm, light, looks good, bungees and platform area just right, can use on my hardtail or full suspension bike. easy to fit
Weaknesses: Not designed for Kona seat posts, which are 27.0mm. Using the shims supplied, it was impossible to get the mounting tight enough without over-stressing the bolts, hence to rack swings away from its centre position. I had to experiment with improvised shims (e.g. cut-offs from old inner tubes!)
(I have the non-QR version - two allen key bolts on a locking collar). A good idea but they need to sort out the locking collar and shim business - it's a struggle to set up on narrow seat posts.

Strengths: nice looking design, light-weight, able to remove with little hassle, rubber bungee works great to hold down u-lock
Weaknesses: swayed on seatpost, even with rubber shims supplied. a little bouncy over the curbs when weighted out.
My problem is that a conventional rack won't attach to my bike due to the cable disc brakes are in the way.
The best shim I've used is a sheet of rubber gasket material from the auto parts store. I'm anxious to get the quick release bag with the fold-out panniers (really nice!), but need to make sure the rack stays put so the pannier frames stay out of the spokes. I'll might consider getting the Topeak QR Basket.
Topeak would do well making a bolt-on version with a smaller post hole.

Strengths: Combines with Topeak back for easy attachment
Weaknesses: Does not hold onto seatpost securely. Limits wedge bag that can be attached
I liked the easy locking of the Topeak bag and rack as I use it for commuting every day, however the rack would not stay straight on the seatpost. It annoyed me so much, I gave up and bought a fixed rack instead. It also was very close to the seat and limited what wedge bag I could have under the seat.
Strengths: kind of lightweight for such a thing, stiff(but only in itself)
Weaknesses: rotates on the seatpost, allows only 12kg(though enough for short trips), ruins the suspension bearings
I used the thing for two 2-3day trips. First time I had only my sleeping bag on it, 2kg weight are ok with the thing, slight roations though. Second trip: 12kg(sb, tent,sidebags). Held the weight quite well, but it got loose every hour( plastic distance plates around the seatpost were shrinking)and it rotates while riding corners, standing up, leaning the bike on a wall... . the trip also included root tracks and that was the end for my bearings, kind of. 12kg roating on your seatpost have a real bad effect on your riding and your frame.

Strengths: Works fine for light loads. Doubles as a fender. Gets the job done (well my job anyway)
Weaknesses: Heavy. Included bungees don't work. I wouldn't use it off-road and I wouldn't depend on it to carry heavy (10 lbs plus) loads.
I bike commute and bought the rack to get some weight out of my backpack and onto the bike. Since I bike through the Bronx and lock up outside, I use a U-lock plus a heavy cable. Now I put my locks, pump and tools in a small duffel bag and strap it to the rack with a couple of heavy bungees.(sold separately, the included ones were not up to the job). The rack stays put and this arrangement works fine. It makes some noise on curbs and potholes. If you have a fat seatpost and a specific problem to solve, maybe this rack can help you. I wouldn't take it off road, or trust it with more than ten pounds or so, or use it with a thin post. As a bonus, I think it looks much cooler than the normal rack with the little legs.
