3M Diamond Grade BlingStrips with protective coating for abrasion resistance. Our BlingStrips have been tested up to 25 psi. The strips are durable (the first units are still rolling clean and strong). We ship you tape trimmed close to the width needed fit between your rim's bead shoulders on 26", 27", and 29" rims (be sure to specify size). Weight depends upon the width needed. For example, 2 stock Specialized FatBoy rim strips weigh 111g while 2 of our BlingStrips cut to fit weigh just 97g. These are cut to fit 27,5" Fat wheels. They will need to be cut down for 26" wheels to eliminate the overlap.
