Will I notice a difference after installing CushCore?

  • Absolutely.  The feeling of riding with CushCore is not a subtle difference from standard tubeless tires.  Even novice riders notice the differences right away.  It is a confidence-inspiring riding experience.  Need evidence?  Check our lab test data and rider feedback.

Does CushCore work with “plus” sized rims and tires (2.8-3.0″)?

  • CushCore will fit on plus-sized rims and tires, but the current design is not optimized for this application.  The lateral stability and sidewall damping benefits will be reduced.  Impact absorption, rim protection, and flat prevention benefits will remain intact.

What wheel sizes will CushCore make next?

  • Our 26″, 27.5″, 29″, and 27.5+ versions are currently available.  Other sizes and applications are currently in development.

Will CushCore fit my rims and tires?

  • See fitment specifications HERE.  Within the size recommendations, CushCore works well with every rim and tire on the market.

Is CushCore difficult to install?

  • No. Installing CushCore is similar to installing standard tubeless tires, but there are a couple unique steps you need to know.  For that reason, we highly recommend watching the Installation Video before you begin.
  • Installation by a first-time user should take no more than 30 minutes.  Installation by an experienced user should take 5-10 minutes.
  • Certain tire & wheel combinations are harder than others.  Wire bead downhill tires, for example, might require a helper – one to work the tire levers, and another to hold the tire bead in the drop center of the rim.

Is CushCore compatible with tubless tire sealant?

  • Yes.  We recommend STan’s No Tubes, Effetto Mariposa Cafelatex, Hutchinson Protect Air Max, or Trucker Co tire sealant.

The installation instructions recommend injecting tire sealant with a syringe.  I don’t have a sealant injector.  Can I still install CushCore?

  • Yes.  Instead of injecting the sealant after the tire is fully mounted, simply pour the sealant directly into the tire before installing the second bead.

What if I get a flat?

  • CushCore provides the highest level of protection against flat tires, but nevertheless a flat tire is still possible.  While CushCore is not intended to be a run-flat tire, it is possible to “limp home” short distances with significantly reduced risk of rim damage.  Otherwise, we recommend using the same approach riders use with standard tubeless.  Carry a lightweight inner tube with a long (48mm) valve stem as a backup.  You may either (1) install the tube circumferential around the CushCore and force the air valve directly through the insert and rim valve hole, or (2) remove the CushCore and replace it with the inner tube.

What tires should I use with CushCore?

  • Tire choice is a personal preference, and the best choice for you depends on several variables.  In general, CushCore makes it possible to run lighter, faster-rolling tires without sacrificing lateral stability, impact absorption capacity, or flat resistance.  For that reason we suggest trying a tire in a lighter weight class than you normally use – for example, a 750 gram tire instead of an 950 gram tire.  If you are already using a lightweight tire, try reducing tire pressure as described below.

What tire pressure should I use with CushCore?

  • Many riders find their preferred pressure with CushCore to be about 5 psi less than their normal tire pressure with standard tubeless. We encourage you experiment to find your own preferred setting.  Start at your normal tire pressure and begin dropping in 2 psi increments until you find the pressure that feels best.

How long will it last?

  • CushCore inserts are extremely durable.  Our foam is engineered to withstand repeated pounding without degradation.  It does not absorb liquid and is not affected by tire sealant.  Ultimate service life depends on your riding frequency, tire pressure, terrain, and other factors.
