ZTZ 26"/27.5"/29" Mountain Bike Wheelset，Ultralight Aluminum Alloy Rim 32H High Strength Bike Wheels， Quick Release Disc Brake MTB Wheel Set， Compatible 7-12 Speed Cassette

bought for a midline Giant Roam that was nice, except the wheel bearings were toast. This replacement is stronger than those factory Giant rims, higher grade hub cartridge and it has a large number of cartridge bearings instead of the old cup/cone type that constantly need adjustments and regreasing. These rims roll smooth as glass. the freewheel clicks pretty loud- which is a cool upgrade and it makes aimless joggers/walkers/runners stop, turn and look to see whats going by them - a safety bonus. I had to move over the shimano gear cluster (which requires 2 tools - one to hold chain in place and special star socket that unbolts the cluster -- OR just buy a $20ish cluster with the teeth numbers you want as an upgrade in range. I didnt need to even adjust my gears. I ordered 12 gold disc torex bolts here for about $8, used a torex bit and a dewalt 1/4' brushless driver and buzzed off the discs and transferred them to this new set in about 10 minutes. The rim size is true 700c so the giant tires and a set of continental tires could be changed without tools. 44mm and 32MM tires seated on the bead without an issue. rims were true and straight out of the box. Arrived on time/fast. I would definately buy these again and recommend to friends/family/coworkers. tremendous value for the money.

Good value, lighter than my oem, and they work great. My only complaint is how loud they are. Since my hearing is bad I only hear them when the bike is in the stand and the casset is close to my ears though:) My riding partner says they are loud though.

Great buy. Highly recommended. Very responsive, but if you don’t like the beautiful sound they make then they might not be for you. They sound similar to industry 9 hubs just a tad less aggressive. For those that can’t tell, the free hub is hg. I’ve had mine for almost a 2 months the rim is still true, and it’s not like I’ve rode light with them they’ve been through some heavy cases and some other high impact stuff! Also very easy to install, just as easy as any hg free hub! In conclusion, if you’re looking for an inexpensive, nice sounding, great actuation points/responsive, and reliable rear wheel, this a great option!

good wheel. fits a 12 speed hg cassette, which is what i was looking for. freehub is not quiet like others have said, sometimes this is useful. the wheel isn’t completely straight and there is some extra runout that i can notice sometimes. won’t take a lot to straighten. packaging was good, no damage.

I ordered the back wheel and it seems good and as promised. It is noisy but solved easily with grease. I spent more time disassembling it (just pull it apart) than greasing it.

This rim is great. I love the aesthetic of it. I got the front wheel one as a replacement so I can add my new disc brakes (I’m restoring an old rim brake bike). Not too noisy once greased down. Very easy to install onto frame with the quick release. Very much worth the money. Fits 26x2.25 tires incredibly easily, and they were brand new tires, so that’s pretty nice. Spins well. Not much more to say. Great rim.

I usually buy brand name wheel/hub but in this economy I gotta give the ZTZ a try. It was $80 and I was skeptical at first but after 2 months of 2-3 rides/week it has been very pleasant so far. I bought the 27.5 front wheel to replace my 10 year old cup and cone bearing MTB front wheel that is well worn and has a bent axle from a crash. Pleasantly surprised at the quality of this wheel. It came perfectly true right out of the box and the spoke tension is symmetrical. Rode over 300 miles(paved and unpaved trails) with this new wheel since and it has been holding up excellent. No play, no rattling, no noise. It's not the lightest wheel out there in terms of weight but I don't feel the effects of the weight when accelerating or climbing. I feel that getting good quality tires with low rolling resistance and light weight are more important. This wheel has very low friction/rolling resistance, I put my new tire on and spun it to 120 rpm and it spun for 4min and 7 seconds before coming to a complete stop. This is >30 seconds longer than my much more expensive rims/hubs! I have been rough a few times, ie: did a few small jumps, hit some potholes, and had a few soft crashes here and there and the wheel has held up fine for the most part but it has some minor buckling(untrue) at different spots, which I had to true it up myself but nothing major, this is expected of a rim this price. Overall 4.5/5.

The media could not be loaded. Something is wrong, 9 speed cassette when torgued to spec will still have a lot of play. I cannot ride on this. Problem is i already installed tubeless and the rotor smh. It seems like a nice solid rim, lightweight and i like how the hub sounds.
