WTB Scraper i40/i45 TCS Tubeless Alloy Rim


It started it all and was the first to deliver legendary tubeless technology to the plus-size market. Why have a large 2.8-3.0” tire if you can’t experience a lovely tubeless ride? Experience TCS euphoria with our Scraper rim, and understand what this plus-size grinning is all about.


  • Wide 40mm and 45mm widths designed to provide support for 2.8” and 3.0” Plus tires at low pressures.
  • 4D angled spoke drilling eliminates binding and lateral loading, and disperses tension more evenly over a greater area. Allows for use of regular J-bend, non-proprietary spokes.
  • TCS inner profile guarantees easy, reliable tubeless retention.
