RDM Nytroblack C75 75% Carbon
Couldn't load pickup availability
The Dynafiber RDM Nytroblack C75 is a reduced diameter windsurf mast with 75% carbon (Toray T700 fiber). It is the ideal compromise between responsiveness and impact resistance: performance close to a top-of-the-range mast at a more affordable price.
Available in lengths of 340, 370, 400 and 430 cm.
Main features
- 75% carbon + 25% fiberglass: more tolerant during falls and impacts in shorebreak.
- Progressive flex: the rig is easier to handle in gusty winds.
- Constant Curve: compatible with the vast majority of modern sails (NeilPryde, GA-Gaastra, Duotone/North, Goya and others).
- Reduced diameter (RDM): comfortable grip during maneuvers and thick walls for greater strength.

Q&A – Frequently Asked Questions
Q: Is the mast compatible with my sail?
A: The Constant Curve is compatible with most sails on the market. Always check the recommended length and mast type (RDM/SDM) on the sail.
Q: Which length should I choose?
A: The one indicated on the sail (luff) or the one immediately below, compensating with the extension.
Q: Why choose a C75 instead of a C100?
A: For greater impact resistance and a lower price, with a small difference in weight and responsiveness: it is the “battle-ready” mast for waves and frequent use.
Q: Which extension is needed?
A: An RDM extension or an SDM extension with an RDM adapter, available on ZZSURF.
