Update: Check out my updated Tubeless Fatbike Guide for information on the non-split tube tubeless method. The method used here is still relevant, and may be more reliable in situations where bead retention is of greatest concern, such as on rough rocky trails. The non-split tube method described in the guide mentioned above is a little lighter. For the most reliable tubeless system, consider adhering the split-tube to the tire bead to create an airtight unit, much like a tubular tire. (2/16/2014)
Does our home-brew tubeless fatbike system work, as on this tubeless Moonlander? These are goatheads. These are tubeless fatbike tires: 4.7″ Surly Big Fat Larry tires to 100mm Clownshoe rims. These two wheels are entirely cluttered with spiny goathead thorns– perhaps 500 in total. This is no match for a tubeless system and some Stan’s liquid sealant. Ride on.
