Road Bike Ultra-Light Sealed Bearing 700C Wheels Wheelset Only 1650g 30MM Rim

I love everything about these wheels. light, look great, sound great, dirt cheap. But.... After about 300miles of hard climbing and fast downhill they're toast. Front has a flat spot on it. Rear got really lose and started popping and snapping. Here's the deal. I weigh 210lbs (95Kg) and I climb steep and crank hard. If you're a light fast guy like lots of my riding buddies are - go for it; you can spend hundreds more for wheels not as good. But if you're a Clydesdale like me, stick with high spoke count HD wheels. UPDATE I discovered that what I thought was an out-of-round wheel, was actually the tire not the wheel. But here's what you need to be aware of: FIRST when you get these wheels - throw out the plastic rim strip that comes with them and replace them with fabric tape. I've had 3 flats on two sets of these wheels because of the rim strips. They don't cover the spoke holes because they're loose and shift. And if you run high pressure (100PSI+) they get pushed into the spoke holes and make little bubbles. You will also discover machining chips under the rim tape that needs to be cleaned out. SECOND Before you ever put them on the ground, tighten the spokes on the rear wheel especially. The non-drive side spokes are too loose. You will need a truing stand to not change the dish as you tighten. Then check the spoke tension after you've run them awhile. If you're willing to do this, these are a great set of wheels. Especially at the price.

One week in and several miles per hour faster and at 190 some lbs these wheels work great going to order the mountain wheel set. 9-17-2017 still rockin the wheels no bends or other issues had to true them only because of natural stress trued them at a park bench the action at turning the wrench is smooth and responsive very nice good job WHOOL.

Cassette (SHimano 10 speed) will not fit correctly because the spline is not manufactured correctly. I assemble the cassette to a Shimano hub and it works perfectly but when assembled to the JKLapin wheel it won't seat correctly and is totally unusable. I really liked these wheels and the weight but I cannot use the rear wheel because it does not fit a brand new Shimano cassette I bought that is supposed to be compatible. Also, it only came with one spacer ring and nothing for other cassette sizes and the product description says it is compatible with 8-9 or 10 speed cassettes. Update: I found the problem. 1. There is a manufacturing defect in the machining of the spline part of the hub (where it keys into the cassette) along the length of the spline there is an area near the bottom where there is a fillet that shouldn't be there (causes an interference). 2. At the bottom of the spline the diameter of the slotted areas increases ever so slightly which prevents the cassette from seating. The things I liked about the wheel sets: 1. Light, I did not validate the weight but if they are what they say they are the wheels are pretty light 2.Nice rims and braking surfaces 3. Decent looking and they arrived very true with consistent spoke tension across the wheels What I didn't like: 1. Rear spline defective 2. Sealed bearings that cannot be maintained and have a higher rolling resistance than loose bearings with cones (however for the price this is appropriate in my opinion) I am an engineer and have worked in China and done quality control at manufacturing sites there. This is a typical quality control failure where a sub-vendor or the manufacturer has either missed a spec. on the control drawing or the machinist used the wrong setup, tooling or process. Something that can happen to anybody but it could be that a whole batch has this defect. Earlier wheel sets must not have had this issue since the reviews were solid. I also appreciate that the supplier of the set didn't ask me to return them since shipping them back to China would be a hassle. I hope they resolve the problem because I think for the price this is a good set of wheels for everyday commuting or maybe even recreational training because they are light and very affordable and come nicely trued. If not for the quality issue I experienced I would have given 4 stars. D.

I can't believe how fast they got here. Ordered August 4, arrived August 9. Surely this can't be typical but I'm grateful. The good: Pretty true out of the box. Spokes are round, hubs are red. Rear hub makes a lot of noise, kind of a clicking sound. Sounds like it needs lubricating. Not so good: They weigh about 60 grams more than advertised. Without skewers or anything front weighed 767 g, rear 949g, total 1716g. advertised 1650g. This is more than rounding error or scale differences. Not enough to send em back but not exactly right. This is a pinned wheel. The braking surface is machined. The spoke tension is pretty uniform. They are the lightest wheels I could afford. The set is 210 g lighter than my old wheels. We'll see how they ride and whether or not they stay true. Will update
