Surly Nylon Rim Strip

These strips are specifically sized at 45mm wide for 65mm rims like the Marge Lite and Rolling Darryl. While they may physically fit other rims of similar width, they are engineered for the specific spoke hole patterns and cutouts of those Surly models.

Fat bike rims often feature large cutouts to save weight, which can expose your inner tube to the rim bed. A woven nylon strip provides a much more durable, puncture-resistant barrier than standard adhesive tape, which can easily tear or shift under the high-volume pressure of fat bike tires.

No, the woven nylon construction is specifically engineered to resist stretching. This ensures the strip stays flat and secure against the rim bed, preventing it from bunching up or exposing the spoke holes during installation or while riding.

These nylon strips are designed to protect inner tubes from spoke holes and rim cutouts. They are not airtight and are not intended to be used as a tubeless rim tape.

Yes, the 45mm width is optimized to provide full coverage for the 65mm rims they are designed for. It creates a secure, protective barrier that centers well and stays in place without needing adhesive.
