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 tyre, and allows 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 tyre to maximise the contact patch for better flotation, traction, and overall performance.
