Wheels up to 68mm

Detailed guide: choosing the right inline skate wheels up to 68mm

Small inline skate wheels are not just “smaller” – they significantly change the ride: a lower center of gravity, more control, quick acceleration and usually high durability. This is exactly why wheel sizes up to 68mm are so popular in aggressive and stunt skating and are widely used on kids’ inline skates. In this guide, we explain how to choose the right diameter, hardness and wheel profile for your needs.

1) Wheel size: choosing between 60–68mm

The most important factor is your frame’s maximum wheel size. Many frames only support specific diameters – using larger wheels than allowed may cause rubbing.

• Like-for-like replacement: safest option is to buy the same diameter you currently use
• Small upgrades/downgrades: within frame limits, steps of 2–4mm are usually noticeable and safe
• Kids’ skates: often 60–64mm for maximum stability and control
• Aggressive & stunt skating: commonly 58–64mm, up to 68mm only with suitable frames

Tip: If you’re unsure whether 68mm wheels fit your frame, check the marking on the frame or match your current wheel size. You can also browse our full range of inline skate wheels.

2) Wheel hardness: grip vs speed vs durability

Wheel hardness (e.g. 85A, 88A, 90A) strongly influences grip, vibration damping and wear rate. As a general rule: softer = more grip & comfort, harder = more speed & durability.

Surface matters: on smooth concrete, harder wheels feel fast and precise; on rough asphalt, slightly softer wheels often provide better control.

3) Profile & core: how they affect ride feel

Beyond diameter and hardness, profile (shape of the rolling surface) and core design influence how a wheel behaves.

• Rounded profile: agile, playful, easier turns
• Flatter profile: more contact area, increased stability and grip
• Core stiffness: stiffer cores feel faster and more direct, but less forgiving
• Width (e.g. 24mm): common for aggressive wheels – always check frame clearance

Aggressive and stunt wheels are built for high impact resistance. Our range includes models from well-known brands such as Undercover, USD, Rollerblade, Powerslide, iqon and MVX (depending on model).

4) Setups: flat, antirocker & typical uses

Especially in aggressive skating, the overall setup plays a big role.

Flat setup (all wheels same size)

• Pros: fast, smooth ride, good control
• Cons: higher chance of wheel bite during grinds
• Typical sizes: 58–64mm, sometimes up to 68mm with compatible frames

Antirocker setup (small middle wheels)

• Pros: easier grinds, less wheel bite
• Cons: slower, less grip
• Typical: larger outer wheels with very small middle wheels

5) Compatibility: bearings, spacers & width

To ensure smooth rolling, all components must match:

• Bearing size: most inline skate wheels use the standard 608 bearing. Suitable bearings can be found in our bearing section.
• Spacers: ensure bearings are aligned and wheels spin freely. See spacers for more info.
• Wheel width: make sure the wheel fits between the frame walls without rubbing.

Practical tip: brand-new wheels don’t always spin freely by hand. Bearings often need a short break-in period – as long as nothing rubs, this is normal.

6) Wheel rotation, wear & maintenance

Inline skate wheels usually wear unevenly. Regular rotation extends wheel life and keeps the ride smooth.

1. Remove wheels: loosen axles and take wheels out
2. Check bearings: clean or replace if necessary
3. Rotate: swap wheel positions to create a new contact edge
4. Reinstall: tighten axles securely, but do not overtighten
