The Surly TPU, or Thermoplastic Urethane, tube is a tough, airtight material lighter than traditional butyl innertubes. It is designed exclusively for the Surly Molenda tire, and allowed for a custom, oversized 6.2" width that maintains its structure, even when operating at low pressures. With the TPU tube installed, you can air down your Molenda tire to maximize contact patch for better flotation, traction, and overall performance.

A properly set up tubeless fatbike tire is like the holy grail of suppleness and, until now, we've forced you all to piecemeal together a tubeless kit for your Other Brother Darryl rims (Sorry about that. It won’t happen again, we promise… probably). But now you don’t have to do that anymore because our Tubeless Kit has everything you need to ditch your fat tubes. It comes with two of our nylon rim strips, a roll of Whisky Parts Co. tubeless tape, two tubeless valves, and two Problem Solvers Super P-Nuts. Just add your favorite sealant and let ‘er rip.

Surly Rim Strips have one job and they do it well. The 58mm nylon rim strip is purpose-built for the Clown Royal Rim, and Moonlander bike.
