Please read blurb below: Notes: We received these wheels amongst a thousand or so wheels of different sizes and varieties from a well known bicycle manufacturer. Due to the sheer number of wheels, we cannot go through and list each individually, showing all blemishes, etc. The manufacturer we obtained them from placed them in bike boxes with no protection keeping the wheels from bumping into one another. Obviously, this is less than ideal, but that is how they are. It is the buyer's responsibility to read these product details, and not expect 100% perfect wheels. If perfection is your goal, we generally stock high end, well kept, and individually checked wheels for a higher price and a reasonable guarantee to be free of blemishes. Our goal is to provide value based wheels for replacing broken or defective wheels on inexpensive or entry-level bikes. Wheel size is not determined by measuring the diameter of the rim itself. A common 26" rim for example has roughly a 22" diameter. While being confusing, at one point, that rim was paired with a tire, and had a rough diameter of 26". Obviously, tires come in a wide variety of heights, changing their overall outer diameter. All of the wheels that we are selling, unless otherwise noted, are the common sizes. If the buyer has an older, or odd bike, and the tire's width is expressed as a fraction, not in decimal form, it is VERY important that the buyer does his/her best to figure out if they have an uncommon size. For example, 26" rims come in more than one diameter. 559mm bead seat diameter is the common size found in the past twenty or so years. But, if for example, you're trying to replace a rim on an old Schwinn with a tire size of 26 x 1-3/8", a normal 26" wheel will not work since the stock wheel will have a larger diameter. Ball / cone type axles are the MOST common type of bearing system offered on bicycle wheels. However, they are not free of some inconveniences. While being nearly indestructible apart from extreme abuse and lack of maintenance, they often require work to spin with the least amount of friction as possible. Generally, wheels will come with the bearings tighter than most people would prefer. This is not unique to these wheels as it applies to nearly all wheels with this type of hub found everywhere - while seeming unlikely, it certainly is the truth (take it from me, a 20 year experienced mechanic). Normally when receiving any wheel from a wholesaler, a bicycle shop will have a mechanic perform minor truing, and hub adjustments before placing the item up for sale in the store for a higher price. Due to the sheer number of wheels, wanting to keep prices as low as possible, we will not be performing that service. It is the buyer's responsibility to ensure that the wheel is appropriately adjusted. While it may seem a daunting task, most of these wheels will function without much work done to them, if any. While not spinning well by turning an axle with your fingers, once the force of a rider is applied, multiplied by the radius of the wheel, it is more than enough torque to get a wheel to spin. If optimal performance is desired, we recommend performing minor truing and axle ball/cone adjustments. Ball / cone hubs require some maintenance throughout the life of the wheel. If axle does not spin well, it is not defective, it just needs adjustment. Ball cone hubs operate
