FAQ

 

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?

  • The 26" version is due out in fall 2017.  Products for 27.5+, 29+, cyclocross, and gravel bike are due out in winter/spring 2018.

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.
  • If you need help, contact us for assistance.

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 a high level of protection against flat tires, but it is still possible to get a flat.  Since CushCore reduces the risk of rim damage, one option is  to "limp home" short distances without attempting to repair the flat.  Otherwise, we recommend using the same approaches riders use with standard tubeless.  Tire plugs (such as Dynaplug) are a good option that do not require removing the tire.  Another option is to carry a lightweight inner tube with a long (48mm) valve stem.  In the event of a flat, force the valve stem through the foam so CushCore can remain inside the tire.  Of course, you can also remove the insert entirely and replace it with a 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.
