Because it is a buckle design, it must be gently pressed into the 70% position during installation, and the rest of the place is gently pressed with a screwdriver or other tools until the buckle is completely inside the bearing, and then it is fully pressed into the bearing. When you hear a click, the installation is successful.

Important reminder: Do not press all the force directly, this will cause damage to the protective cover.

Many riders replace the new bearings and cause the original dust cover to be damaged and cannot be installed. This can be a good replacement. No tools are needed. Manually press it to install it. It is very convenient. After the crank is locked, there will be no loosening. One axis needs two
