Wheels Manufacturing Sealed Bearings MR 17287

You need to verify the dimensions of your current bearings. These are 17 x 28 x 7 mm, so you should measure your existing bearings with a caliper or check your hub manufacturer's technical documentation to ensure they match exactly.

ABEC 3 is a standard for precision and tolerance. It indicates that these bearings are manufactured to tighter tolerances than standard, non-rated bearings, which generally results in smoother rotation and less friction in your wheel hubs.

These steel bearings are durable enough for both road and mountain bike use. However, because they are standard steel, they are best suited for general riding conditions rather than extreme, muddy, or wet environments where specialized sealed or ceramic bearings might offer better longevity.

Yes, you will need a bearing press or a drift set specifically sized for 17mm inner diameter bearings. Using a hammer or improper tools can damage the bearing races and compromise their performance before you even start riding.

This package contains two bearings. Depending on your specific hub design, you may need more than one pair to service both the front and rear wheels, so be sure to check your hub's service manual for the total count required.
