I have a Santa Cruz Bronson that came stock with RaceFace rims.. These are not compatible with CushCore. Only after I installed these and ruined two perfectly new tires did CushCore change their website to indicate its not compatible with these rims. CushCore did not perform well and the one ride I did with them - almost impossible to seat and quickly leaked sealant. Make sure you choose a rim with a deep enough wheel well! And, do not use any force to install these, despite what the video may indicate...
