Stan's Original Rim Tape creates a durable and airtight seal between tubeless rims and tubeless tires, creating an ideal environment for tubeless sealant to remain liquid for as long as possible. The non-porous material protects the interior of alloy and carbon rims, in addition to their spokes and nipples, and a synthetic adhesive leaves zero residue behind once removed. As a general rule of thumb, we recommend selecting a tape 1-2mm wider than the interior width of your rim. -One 10-meter roll will tape 4 x 29" rims or 5 x 27.5" rims -Creates durable, airtight seal over spoke holes -Completely non-porous vapor barrier seals rim interior from moisture -Adhesive leaves no residue on rim, once removed -Low friction surface helps tire beads slip into place
