Duotone Mast EPX.90

FAQ

What is the Duotone EPX.90 mast and who is it suitable for?

The Duotone EPX.90 is a 90% carbon windsurf mast with a prepreg construction and autoclave manufacturing, offering high-end performance at an affordable price. It is suitable for demanding freeride and performance windsurfers looking for a lightweight, dynamic carbon mast.

In which lengths is the EPX.90 available?

The Duotone EPX.90 is available in five sizes: as RDM in 370, 400 and 430 cm, and as SDM in 430 and 460 cm. The respective IMCS values are 17, 19, 21, 21 and 25.

How much does the Duotone EPX.90 mast weigh?

The weight varies depending on the size: RDM 370 weighs approx. 1.55 kg, RDM 400 approx. 1.65 kg, RDM 430 approx. 1.85 kg, SDM 430 approx. 1.95 kg and SDM 460 approx. 2.10 kg (tolerance ±8%). This makes it significantly lighter than a comparable aluminum mast.

What bend curve does the EPX.90 have and is it compatible with other sails?

The EPX.90 features the Duotone Medium Constant Curve (61-63% at the bottom, 75-77% at the top). This bend curve guarantees maximum compatibility with all Duotone sails and is identical to the brand's higher-end mast lines.

For which system is the EPX.90 optimized?

The EPX.90 is specially optimized for the Duotone EPX system. This makes it the right carbon mast for the EPX base, fork and extension, complementing Duotone's modular EPX hardware program.

What does the prepreg construction of the EPX.90 mean?

The prepreg construction ensures dynamic reflex behavior, a lower center of gravity and improved durability. The autoclave manufacturing process eliminates excess resin and creates the strongest possible final matrix, making the construction lightweight, durable and extremely consistent from mast to mast.

How many variants of the EPX.90 are there and how do they differ?

There are two designs: RDM (Reduced Diameter) in 370, 400 and 430 cm for classic and more compact sails, and SDM (Standard Diameter) in 430 and 460 cm for larger wave and freeride sails. Both variants share the same 90% carbon prepreg construction and bend curve.

What does the name EPX.90 stand for?

The number 90 stands for the 90% carbon content. This positions the EPX.90 between the more affordable EPX variants (e.g. EPX.40) and the even lighter 100% carbon masts such as Duotone's Platinum series.
