A fin that will give you amazing speed and control, secure and loose carving on the fast flats or choppy waves.

The 3SW also works great in big wave boards.

Fins K4 Fins Bubble £42.50
Bubble – Freestyle

The Freestyle fin developed with Andy ‘Bubble’ Chambers. Originally there were two different prototypes; one worked great on flat water but would let go in the chop, the other was rock solid in the chop but too grippy on flatwater. The BUBBLE freestyle fin has the perfect blend of grip to be secure in the chop and into carving manuevres, whilst still allowing plenty of release for double spins. A fin you can take anywhere which won’t let you down. Grip in the toughest conditions.

The Ezzy front fin has a similer template to the Stubby but with a wider chord. A fully asymmetric foil with a radiused front and slightly positive inner foil to aid flow at high speeds. Choose a smaller fin size for less drag, same power. Great for huge gouging hooky cut backs!

Choose the degree depending on your boards box angles.

Fins K4 Fins Fang £69.90

FANG – Free ride fin.

This fin is the culmination of years of R&D with new materials and new fin designs. We made numerous prototype moulds and moulded them in several materials until we found the best combination. We then refined the prototypes to arrive at the Fang Freeride. A fin that will give you amazing speed and control, secure carving and let you fly upwind. The material is K4’s ‘Super Stiff’, the ideal composite for Freeride fins; great reflex, stiff enough for excellent acceleration and direct response, enough flex for speed, grip and control.

The original fin for performance wave riding and the first choice for pro team riders whether twin, quad or thruster. Great flex for amazing grip and looseness on the wave. Raked template for control. A progressive foil for different flows between tip and base. Will loosen up a ‘stiff’ board and are particularly sweet as twin fins as they eliminate that unwanted top turn spin out.

Fins K4 Fins Rocket (front) £59.90

Rocket – On Shore Wave

The smaller Rocket fins, for use as quad/tri fronts or trailer fins. Lifty upright stiffer design with no swept tip for extra speed.

The Rocket wave fin. Almost like having slalom fins in your wave board! Lift, drive and speed for onshore conditions. Great for early planing and jumping. Also surprised us with their DTL performance but you’ll need to use your rails for powerful turns as they don’t have the same grip’n’whip in big cut backs and snaps as with the flexier fins.

Fins K4 Fins Shark II (front) £39.90

Shark II – Fronts

The all new SharkII fronts. Our team riders wanted a fast and grippy fin for both their quads and thrusters. So we set about designing a fin that was sleek and lower tip area using our ‘super stiff’ material. We slimmed it right down to give back some flex and grip, and widened the base to add hold and drive. The result was a fast and precise feeling fin with just the right balance of grip and release. Already taking Alex Mussolini to a podium finish in Tenerife.

Fins K4 Fins SUP Race £40.00

SUP race

The swept back SUP race fin. 45 degree rake so you don’t have to worry about weed or debris.

Foil optimised for paddling speeds, but taking many pointers from our speed windsurfing fins. In fact I stuck this yellow fin in my windsurf and did 48mph on it!
Dynamic Flex material gives more grip, better tracking and more speed than stiffer materials. (Fins with flex are always faster than stiff fins when the loads and AOA are low)

Already proven on the SUP race course with Andre Le Geyt finishing 7th in the 11 Cities.

Choose the degree depending on your boards box angles.

Our Freestyle fin developed with up and coming freestyler Nic Hibdige. This is a fin for modern freestyle, plenty of lift, pop and release to spring you into the next spin!
