Rollerblade Hydrogen BLANK 64 mm / 92A light blue/grey (4 pcs) are four wheels for aggressive skates with a very high hardness of 92A. They work well in the skatepark for tricks, jumps and grinds, and the premium polyurethane compound limits tread wear.

## Who it’s for

- You skate the skatepark on aggressive skates with a frame for 64 mm wheels and are replacing worn or flattened ones.
- You do jumps and grinds and are looking for hard wheels that roll quickly on smooth ramp surfaces.
- You want larger wheels than 60 mm so that it is easier to hold your speed between obstacles.

## When to choose something else

- You skate in the city or recreationally — 64 mm / 92A will be slow and hard on asphalt, see [80 mm wheels](https://bogdanca.pl/en/wheels-and-bearings/wheels-80mm).
- Your frame takes 60 mm at most — this series also includes [BLANK 60 mm / 92A](https://bogdanca.pl/en/rollerblade-hydrogen-blank-wheels-60-mm-92a-square-4-pcs.html).

## Key features

- **64 mm diameter** — Still a small wheel for aggressive skates, but it rolls slightly longer than 60 mm; it needs a frame with room for this size.
- **92A hardness** — A very hard tread rolls quickly on the smooth surfaces of a skatepark; on rough asphalt it transmits vibration.
- **Premium polyurethane compound** — It gives good riding properties and slow wear despite jumps and tricks.
- **Set of 4** — Four wheels are a set for one skate with four wheels of the same diameter; for a pair you need two sets.

## Questions and answers

### Are 4 wheels enough for a pair of skates?

Not always. Four wheels are a set for one skate with four wheels of the same diameter, so for a pair you need two sets. In an anti-rocker setup, with two large wheels per skate, one set is enough for a pair.

### Are bearings and spacers included?

No. The set is just 4 wheels. You move the bearings and spacers over from your old wheels or choose them separately.

### Will these wheels fit my aggressive skates?

Yes, if the frame takes 64 mm wheels. Check the print on your current wheels or the largest diameter permitted for your frame.

### How do they differ from BLANK 60 mm?

In diameter: 64 instead of 60 mm, with the same 92A hardness and the same number of wheels. You can find the smaller one here: [BLANK 60 mm / 92A](https://bogdanca.pl/en/rollerblade-hydrogen-blank-wheels-60-mm-92a-square-4-pcs.html).

### Can I return the wheels?

Yes, you have 14 days to withdraw from the contract (return) without giving a reason. The buyer covers the return shipping.
