The New Harmony hollow carbon weave endpin is lighter than the solid carbon endpins and can be an excellent choice for cellists looking to make their instrument more resonant. This endpin weighs approximately 50grams.
The endpin can easily slide into fittings originally designed for hollow metal rods; take care not to over-tighten the screw, however, as this can damage the carbon fiber. If properly cared for, this endpin can be used for many years in standard cello endpin fittings.
This is the 10mmendpin, which comes in only a 20" length.
