Fingerboard Parts Guide

Choosing the right fingerboard setup can feel overwhelming at first, but this guide should help simplify it. Here’s a breakdown of everything you need to know when picking your trucks, wheels, decks to make a complete setup. 

Sizing: Matching Trucks to Decks

All trucks use a standard mounting size, meaning they’ll fit any deck. But for the best performance, match your truck width to your deck:

• 29mm trucks → decks 29–31mm

• 32mm trucks → decks 31.5–33mm

• 34mm trucks → decks 33.5–34.5mm

• 36mm trucks → decks 35mm and up

👉 Pro Tip: Larger wheels will stick out beyond the trucks, while smaller wheels (like Oak Minis) stay neatly inside the truck width.

Complete Fingerboards

There are 2 mains options for packaged completes :

• Pre-Setup Completes – ready to ride straight out of the box with even the deck gripped with tape. (Such as Berlinwood and DKFB completes)

• Unassembled Completes – build it yourself for a more hands-on experience. (Most other completes at Radical)

Every complete includes:

• Fingerboard deck

• 2 trucks

• 4 wheels

• Foam grip tape

• Hardware (8 screws, 4 nuts, 1 tool)

👉 If you’d rather skip the assembly, we also offers a setup service where a Radical team member will assemble your setup before shipping.

Wheels

Fingerboard wheels come in two main materials:

• Urethane Wheels – Softer, grippier feel with smooth performance.

• Plastic (POM) Wheels – Firmer, slicker, more prone to skidding (great if you like squeeky powerslides) and in turn makes them extra smooth. 

Most entry-level completes come with basic plastic bearing wheels, while higher-end wheels use:

• Better shapes and more options for shapes and size of wheels

• Higher-quality materials

• Precision bearings (like ABEC 9) for smoother, longer rolling

Trucks

Fingerboard trucks fall into two main categories:

• Low-End Trucks – Cheaper builds, often using o-ring bushings. Functional but less realistic and often made partially of plastic.

• High-End Trucks – Fully metal, engineered to replicate skateboard trucks, and use moulded conical bushings for smooth turning and durability. They also grind more smoothly and realistically due to high-quality materials. 

Decks

All fingerboard decks share similarities, but higher-end ones stand out with:

• Handcrafted quality and made of premium hand selected wooden plies

• Advanced moulds for consistent shape and more pop

• “Real wear” graphics that are designed to scratch and fade with use like a real skateboard deck

Deck Options at Radical:

• Available in Sizes: 29mm to 36mm

• Shapes: Classic popsicle, directional old-school, and more (if you're looking for a unique directional shape definitely check out DK fingerboards instock at Radical)

• Moulds: Different levels of kick and concave, ranging from flat/low concave to steep/high concave
