7.25" classic single

¥13,405 JPY Sale Save

Alkali Fins

Color Clear

The Classic Single is a staple for short boards both old and new.

Stubby base for stability and drive, with an upright rake that helps pivot off the lip.
The foil is thinner through the tip to give a lively feel through turns.

Surfing's early shortboard era was full of surfer-shapers who relentlessly tested and refined their equipment in the world's best waves. Guys like Dick Brewer and Terry Fitzgerald were creating fins that helped them attack waves and match the power of waves like Sunset.

Alkali’s Classic Single draws inspiration from the designs perfected in the 70’s by the icons of that time.
