CAUTION! Read before using a Silicon Nitride Endpin:

Saddle Rider Music LLC offers Silicon Nitride endpins for research purposes at our cost plus a small handling fee to cover the surgical steel tip installation and other manufacturing and distribution expenses.  Despite their popularity among cellists, and the impressive qualities of Silicon Nitride as a “super-ceramic,” they must be used with care.  We manufacture our endpins using the highest quality materials and processes available and have never heard of one breaking.  That said, there have been isolated instances of Silicon Nitride endpins made by other manufacturers fracturing.  Such a mishap is extremely unlikely under normal use. Cellists should exercise caution not to subject the endpin to shocks such as dropping it on a concrete floor or to hard impacts especially when extended from the cello.  We warranty our Silicon Nitride endpins against breakage under normal use. When installing a Silicon Nitride endpin, USERS ASSUME ALL RESPONSIBILITY BEYOND THE PURCHASE PRICE OF THE ENDPIN.
