If you do inline skating frequently, then the quad skates need replacement. Are you looking for the parts of inline skate that need changing? 

If yes, then you’re on the right page. 

Generally, inline skates have two to five wheels organized in a straight line. It provides more control over speed and is best for professionals or aggressive skaters. 

In this guide, I mention a detailed note on parts of inline skates and when they need replacement.

So without further ado, let’s dig in depth. 

Enlist The Parts Of Inline Skate


The high shoe or boot is the best for beginners because it provides more ankle support and is easy to skate. Speed skaters are mostly equipped with carbon fiber boots that give enormous support and more ankle flexion due to lower cuts. 

Aggressive skaters or professionals prefer rugged boots or mix or hard and soft boots. These protect their feet against consequences and provide reasonable control on skating. Rugged boots may include a shock-absorbent pad and protect your feet during high-speed skating. 

Recreational skaters prefer a soft boot that provides excellent ankle support and is easy to use. Also, downhill skaters usually use boots fitted with soft foam lining and heat-molded to the shape according to foot. 


Recreational players usually use that skate whose frame is made up of high-grade polyurethane. It provides a great structure to inline skating. Moreover, skates that are made in the low-end department may consist of other types of plastics. 

Professionals typically use speed skate frames composed of carbon fiber, extruded aluminum, or magnesium. This type of material is costly but more solid and durable. Some skate frames are made from pressed aluminum, which is affordable but less durable. 

Carbon fiber frames are specially made for smoother skating, and generally, they are expensive but more flexible. Also, it manages the worst power transfer between the leg and the wheels. These frames usually weigh 160 to 180 grams (5.6 to 6.3 oz). High-end carbon fiber frames have been introduced into the market with a monocoque construction. Their weight is around 130 grams (4.6 oz, providing the same level of stiffness as an aluminum frame. 

Aluminum frame lengths range from 230 mm (9.1 inches) for two-wheel frame freestyle skates to 325 mm (12.8 inches) for four or five-wheel short-framed skates. 


Bearing on a skate enables the wheel to rotate smoothly and freely. Generally, bearings have an ABEC rating; in this rating, precision tolerance ranges from 1 (worst) to 9 (best). High-rated bearings have the best quality overall, and the ABEC standards are specially for high-speed skates. 

These standards did not specify some factors, including ball precision, material, load handling capacities, degree of ball and raceway polishing, lubricant, and vibration. 

  • ABEC 1 bearing is the least accurate and affordable. The material quality is usually low. 
  • ABEC 3 skateboard bearings can not roll smoothly or rapidly and are commonly inexpensive. 
  • ABEC 5 bearings are used in most inline skates, giving you fast speed at a reasonable price. 
  • ABEC 7 bearings are slightly expensive but roll fast and smooth. 
  • ABEC 9 bearings are the best and incredibly fast. Best for downhill skating. 

Bearing consists of a C-ring, outer ring, bearing shield, inner ring, steel balls, ball retainer, and rubber seal. Inline skate bearings work best when every part is working appropriately. 


Wheels on an inline skate are as valuable as tires on the car. Wheels come in different sizes measured in millimeters. Also, skate wheel size relies on skating styles such as:

  • 44 to 72 mm size is best for aggressive skating.
  • 47 to 80 mm suitable for roller hockey skating
  • 68 to 72 mm is for artistic inline skating
  • 72 to 80 mm for downhill and freestyle skating
  • 70 to 90 mm for urban skating
  • 72 to 100 mm for recreational skating
  • 80 to 90 mm for downhill skating and fitness skates
  • 100 to 125 mm for speed skating and mushroom balding.
  • 125 to 150 mm for downhill and off-road skating.

Aggressive skaters usually use small wheels, and speed skaters use harder, faster, and bigger wheels. The essential components of inline wheels are bearings, spacers, polyurethane, and wheel hub. 

The durometer is the second measurement of inline skates wheels, followed by the letter “A.” A. For instance, if the wheel is marked as 76mm/78A, this means 76 mm in diameter, and 78A is the wheel’s hardness. If the diameter is high, then the wheel is more rigid. 

Toe Stops or Heel Brakes

The brake is made from hard rubber that attaches to the frame’s heel and helps stop the skate. To stop skating, you lift the toes of the skate and press the brake on the ground. Toe stop usually uses a crossover turn technique, and roller skaters make a sharp turn by crossing one leg over another without losing momentum. 

However, freestyle and aggressive inline skaters usually don’t use heel brakes because the brakes provide a boundary that limits the skater’s ability to perform effectively. If skates lack heel brakes, there are other methods for stopping, such as T-stop, in which skaters make a T shape to reduce speed by moving one skate perpendicular to another. 

Parts Of Inline Skate – How Long They Last?

The long life of parts usually depends on the quality, how you skate and how often you skate. The roller blade parts (inline skate) probably last a long time. For instance, aggressive skaters do jumping and grinding, so they’ve to change frames and boots yearly. In contrast, occasional skaters go blading once a week, and their skates might last for ten years. Wheels are a component that frequently needs replacement. The inline skate parts need cleaning and maintenance for long-lasting life. You’ve to check bearings and axels regularly. 

When To Replace Inline Skates Parts?

Rollerblade buckles last long if they are made from metal. However, plastic buckles can wear down quickly, so I recommend changing the buckle rather than changing the boot. Brakes and laces need replacement if the skate is used frequently, and overuse brakes will not work appropriately and will not help stop. 

Closing Remarks – What are the parts of Inline skate?

Lastly, roller blades consist of 5 major parts: a boot, wheels, bearings, brakes, and frame. I mention them in detail above, and hopefully, it will be enough detail for you. Comments us for your queries.
