Does anyone know how big of fins come with the One board? I just ordered mine and i was wondering if i needed to get a different size fin because i am used to small molded fins of a premier

Go to ronixwake.com and you can download the brochure with all of the specs.

I belive there 1 inch...

Heck, just ride without one... that way you don't have to bother yourself with fin size!
