Corvus Fatback Big Su Wheelsets

Are you ready to drop some serious rotational weight? Look no further than Fatback’s latest design in aluminum rims, the Big Su. With a weight of 640g, they’re incredibly light, but even more important, properly stiff, and easily set up tubeless. These are by far the best upgrade you can make to your fat bike for the money.

Some rims are light, some are strong, and some are easy to set up tubeless. Pick all three with the Big Su.

Here are the details and options:

  • Rim width is 81mm external and 76mm internal
  • Complete set weights approximately 2500 grams
  • Come with a Thru-axle 15x150mm front and Thru-axle 12x197mm rear – chose between Sram XD or Shimano freehubs
  • Wheelsets shipped taped and tubeless ready
