So we assume you have ordered your Re-Rides replacement Rim Strips for your Mongoose Pro Class BMX Rims. Hopefully they've been delivered and you are ready to install.
Step 1 - Locate the valve holes on your rim. They are slightly smaller than the other holes and may have what's left of the original Pro Class sticker.
Step 2 - Line up the valve hole with one end hole on your rim strips. Hold the rim strip in place and firmly loop the the strip around your rim, keeping the rim strip straight and not crossing over.
Step 3 - Bring both holes on the rim strip together over the valve hole. You'll need to be firm, but don't pull the strip too hard, and don't pull around the cut hole. If you pull too hard, you'll risk tearing the rim strip (being heavy handed, will void any warranty.). Tape the ends together to hold them in place.
Step 4 - As usual with all spoked rims, it's recommended that you also use rubber rim tape to protect your inner tube against protruding spokes. Place your rubber rim tape over the Re-Rides replacement BMX Rim Strips.
Step 5 - At this stage it is normal for your rim strips to look a little crinkled under the rim rubber. Place your inner tube and tyre on the rim as normal and pump up the tyre to the recommended pressure. This is normally 40psi.
And that's it. Your Mongoose Pro Class BMX rims are now done. Stick 'em back on your ride and enjoy.
