## Who it’s for

- You skate fast — marathons, long routes — and want large wheels that hold their speed for longer after push-off.
- The factory 110 mm wheels on your four-wheel skates are worn down and you want to replace the whole set at once.
- You skate freeskate intensively and care about a light, stiff core that transfers energy well.

## When to choose something else

- You are only just starting or mostly skate slalom — smaller wheels will give you more manoeuvrability, see [skate wheels](https://bogdanca.pl/en/wheels-and-bearings/skate-wheels).
- The frame of your skates does not take 110 mm wheels — check the largest permitted diameter or choose a different [frame](https://bogdanca.pl/en/skate-parts/frames).

## Key features

- **110 mm diameter** — A large wheel rolls for longer after a single push-off and copes better with bumps, which matters on long routes and at high speed.
- **85A hardness** — It gives tread durability and a lively rebound; the profile, core and hardness were chosen to balance speed and cushioning.
- **Performance Core** — The light, stiff core is optimised for energy transfer, so less push-off force is lost in the flex of the wheel.
- **Premium Urethane Formula** — The urethane compound gives grip and smooth skating even at high speeds.

## Questions and answers

### Are 8 wheels enough for a pair of skates?

Yes, if you have four-wheel skates. Eight wheels is a set for a pair — four wheels per skate.

### Will these wheels fit my skates?

Yes, if the frame of your skates takes four 110 mm wheels. Check the largest diameter permitted for your frame — they will not fit on a frame designed for smaller wheels.

### Are 110 mm / 85A wheels suitable for a beginner?

Rather not. They are wheels for advanced skaters and racers; it is easier to learn on skates with smaller wheels.

### Can you match spacers to these wheels?

Yes, as part of the separate service “Wheel core measurement and spacer matching”, which you add to your order.

### 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.
