The SROKA Elite 14mm carbon foil is heavier than the average carbon mast because it is made of a lot of high-quality carbon, which gives it exceptional rigidity. The mast is solid and has no foam inside, making it stronger and more durable.
There’s no secret, such a slippery and stiff mast can’t be lighter, unless you use even better carbon fibers, which would make a much more expensive foil.
The extra weight is more than compensated for by its drag without resistance and perfect responsiveness.
For a lighter mast, choose the 16mm SOLO carbon mast.
