Sizes and recommended weight
| SIZE | RIDER WEIGHT | FINS | BOARD WEIGHT* |
|---|---|---|---|
| 153 / 46.5 | Over 40 kg | FS 5.0 Glass 50 | 3.55 kg |
| 164 / 47.5 | Over 40 kg | FS 5.0 Glass 50 | 3.77 kg |

“The Spike Concept Blue saves sessions. You plane early, you're first on the water and you ride effortlessly when there's barely any wind. And it still has enough for jumps and simple tricks.”

Frequently asked questions
153 or 164?+
According to Duotone, both are for riders over 40 kg. The 164 has more surface area and planes earlier; the 153 is a little more manageable.
Can I use it in normal wind?+
It's designed for light wind; in medium or strong wind a standard-size board is more fun.
How is it different from the Spike SLS?+
The outline and sizes are the same. The Concept Blue uses flax and basalt; the SLS uses Innegra and Biax Carbon, and weighs a little less.
