The FIN System™ is a revolutionary Patented new upgrade for the Surf Adapter that allows riders to alter the pivot angle of their Surf Adapter. This Kit can be added to any existing Skateboard setup. 

The FINs can be added in 2 configurations, in addition to a standard 150° Surf Adapter configuration. One configuration is Super Carve 145° and the other is Mega Pump 155°. Super Carve gives you a more responsive turning experience, and lets you carve very tight maneuvers in tight spaces. Mega Pump is a lighter feeling and allows you to efficiently drive the board with small pumps over long distances. 

We are very excited to be offering this system to our riders! We hope that you find the FIN System as transformative and fun as the Surf Adapter itself! 

Customize your Surf Adapter Bushings, and your Rail Adapter Bushings.

Old-school deck and Indys with an adapter

I had a nice old-school reaper deck and Indy 169s, but wanted to get into surfskating after my wife and friend bought Curfboards. I couldn’t go back to cruising and tic-taccing, I’m not going to be catching any air at my age, and I couldn’t justify buying a whole new complete surfskate.

After far too much hesitating thanks to the internet and “your wheelbase is too short” or “your trucks are too big”, I bought the FIN adapter with the bamboo risers.

With the rear risers, 53.5mm high TKPs, and adapter in standard mode, there’s only a small possibility of wheelbite with 70mm wheels. The pre-threaded holes on the adapter appear to add about 1/4in to 1/2in to the wheelbase, and the weight of the adapter actually helps the stability on such a short wheelbase (18in axle-to-axle). It’s exhausting if you want to go fast, but incredible agile.

I’m now riding it in “mega pump” mode with a dewedged rear truck and 66mm wheels, and have extended my deck’s wheelbase a bit front and back so it’s 20in axle-to-axle. It’s more stable and easier to pump at the expense of a bit of agility.

My board is now great fun and a great workout and will get regular use! If you are hesitating, buy one right now!

Game Changer for My Electric Skateboard – Plus, Outstanding Customer Service!

Honestly, adding the surf adapter to my electric skateboard has been a total game changer. I thought I was getting pretty much everything I could out of my board, but this adapter just leveled up the whole experience in ways I didn’t even expect. From the first ride, I could feel the difference, it’s like the turn radius suddenly widened, and carving became this incredibly smooth, controlled experience.

The company was also fantastic and really stands by their product. I ran into some issues during installation, and they actually let me bring it to their location so they could help with the setup. They were super accommodating and went above and beyond to make sure everything was working perfectly. It just shows how committed they are to customer satisfaction, they genuinely want you to enjoy their product as much as possible.

Now, every ride feels like a new adventure. The adapter makes it feel like I’m gliding downhill, even on flat ground, and lets me weave in and out of obstacles with ease. It adds this level of control and smoothness I didn’t know I was missing. If you’re thinking about upgrading your board, this adapter is definitely worth it. The product is great, and the support makes it even better!

The FIN System™ is a revolutionary Patented new upgrade for the Surf Adapter that allows riders to alter the pivot angle of their Surf Adapter. This kit can be added to any existing skateboard setup! 

The FINs can be added in 2 configurations, in addition to a Standard Surf Adapter configuration. One configuration is Mega Pump and the other is Super Carve. 

THREE Distinct riding modes

Each FIN SETTING will be characterized by different pivot angle and ride height. The FIN System has set a new standard for customization of a Surfskate, by allowing for the adjustment of the angle of the primary pivot itself. This angle is the biggest factor in determining how a Surf truck will feel. 

DREAM Surf Truck

FIN System

Set your FINs to Super Carve for an increased responsiveness and high performance. Super Carve is a very lively setting that emphasizes how tightly the Surf Adapter can turn within a space, and carve it to pieces!

Remove your FINs to utilize the Standard Surf Adapter Geometry. This geometry was something that we created with the goal of achieving the most universal surf style performane for riders across the world. It's still as fun as ever to ride the Standard setting!

Set your FINs to Mega Pump for a dialed back high performance cruising feel. The Surf Adapter won't lean as deeply into turns, and the flatter deck angle allows you to gently pump this board up to high speeds with minimal exertion, and maximal forward propultion. It can still carve with a distinctly Waterborne fluidity.

What are FINs?

FINs snap into the Surf Adapter's truck holding Pivot arm. They effectively change the angle that the arm rotates on, and in turn change the way that the wheels move as you press on your rails. This is what gives you a totally new feeling.

DESIGN INSIGHT

The Surf Adapter is an extremely robust design that has been mounted onto everything from 12 inch skateboards to 12 foot long skateboards! It has been paired with every truck under the sun, and riden by people on all 7 continets. We believe that the Surf Adapter's design language, aids in it's mission for universal appeal. This rebust design lan guage is why the FIN System works. Had we taken a more common approach, had we coppied an existign design, or had we put any less consideration, we would not have been able to add these clever little wedges to the Surf Adaper without significant further modification. It is only becuase we found the best solution, the bushing, that we can change the pivot angle and still have the same functionality and resilience.

HOW BUSHINGS AFFECT YOUR PERFORMNCE
