Bones Wheels’ pride themselves on bringing the most advanced technology to skateboard wheels. Their unique formula has been rigorously tested to the point where they claim it is hands down the best urethane on the market. Bones produce several different formulas of urethane, which are available in many shapes and sizes. They collectively cater to all types of skateboarding and give you the widest choice of any wheel brand currently on the market.

There is a huge debate and rivalry between Bones and Spitfire, both companies claiming to be the best out. Bones Wheels were born out of the legendary brand, Powell Peralta, and have been producing skateboard wheels for 40 years. So, it’s safe to say they have both the history and knowledge to manufacture a great skateboard wheel.

Bones state that you’ll be able to find a cheaper skateboard wheel, but not a better quality one. Since day one they have been produced in their own factory in Santa Barbara, California. This ensures a premium end-to-end manufacturing process that they heavily control. The Bones Wheels factory is also where they conduct a vast array of product tests, generating a lot of information regarding their unique production processes. You can check it all out here.

Here’s a breakdown of all the different urethane formulas, shapes and sizes that Bones Wheels have to offer.


To help you better understand the many shapes to Bones Wheels, see below, Each wheel version, such as V1, V2 etc are only available in certain height and width sizes.

Bones Easy Streets Wheels Buyers Guide

Bones Easy Streets Wheels

The Easy Streets are a new wheel from Bones. Put simply, they’re the Bones STFs but in a 99a durometer, so ever so slightly softer than the traditional STFs. There has been some confusion over the naming of this wheel, these are not, in fact, soft wheels, and should prove pretty popular we think.

Bones Bearings are also very highly regarded, they produce a wide range of bearing that cater to all levels of the market. From an entry-level beginner bearing through to the demands of the highest professional rider. Bones have produced skateboard bearings for over 35 years, having pioneered technologies and constantly upped the quality of their production.

Importantly they offer no ABEC rating, for more information on this see our general Bearing Guide here, preferring to rely on the trusted reputation and known quality they have built up over the many years of thier existence. Many people only buy Bones Bearings and don't consider any other options.

The Bones Bearing range is split into Bones Reds and Bones Swiss, two families that offer many different types of bearing within. They cater to all price levels and offer a bearing for every level of skateboarding.

Let's take a look at the full Bones Bearing range:

Bones Reds Buyers Guide


Bones Reds are the entry point in the entire Bones bearing line, they are standard quality bearings with a nylon ball retainer, steel pre-lubricated ball bearings and are rated by Bones as 'Skate Rated'. This means they perform to a certain set of tolerances that reflect their price and position in the bones line-up. They are made in China.

Bones Reds Big Balls Buyers Guide


Big Balls are a new bearing to the Reds line, they are standard build like Reds but roll faster due to having a 17% larger ball bearing. The larger size also means they keep rolling longer and are less susceptible to dirt and grime that can build up in a bearing. They also offer a longer lifespan due to the larger balls.

Bones Reds Super Buyers Guide

Bones Super REDS

Super Reds up the quality further by having superior polished bearing races and balls. The steel balls are also made from higher-quality steel. This not only leads to more speed and longevity but also produces a smoother and quieter roll. An extra feature is black removable shields with laser etching.

Bones Reds Race Buyers Guide

Bones Race REDS

Race Reds and precision ground bearings designed for high-speed skateboarding. They feature high-quality polished steel balls and include a built-in spacer to provide perfect 0.400 spacing between bearings. So your trucks need to be properly tightened at the axle nut to gain maximum benefit.

Bones Reds Ceramic Buyers Guide

Bones Ceramic Super REDS

This is where it gets technical and expensive. Ceramic bearings consist of "grade 5, silicone nitride, hot isostatically pressed ceramic balls". They provide the least amount of friction, as opposed to steel, therefore giving the most speed. Uniquely the super hard balls actually re-polished themselves the more you roll, which alongside Ceramic never rusting, give the long-lasting bearing available.

Bones Swiss Bearings Buyers Guide

Bones Swiss Bearings

The first in the Swiss family and are often all you need. Many skateboarders insist that once you've had Swiss you can never go back. The difference is very noticeable. Bones Swiss Bearings have been produced in Switzerland for over 30 years, which instantly ups the material and build quality. Bones state they offer "professional competition-grade speed and durability". We can't argue and well worth the extra cost.

Bones Super Swiss Bearings Buyers Guide

Bones Super Swiss 6 Bearings

Next up are Super Swiss, these bearings feature 6 balls instead of the regular 7. The design philosophy behind this is to provide even more speed and strengh due to each ball being larger in size. They are similar in quality to regular Swiss Bearings and also carry the made in Switzerland tag.
