# MPC Enigma wheels 90 mm X-Firm (8 pcs)

MPC Enigma 90 mm X-Firm skate wheels are a set of 8 speed skating wheels for racers and advanced skaters. A 90 mm diameter gives better acceleration and manoeuvrability than the larger sizes in the series, while Double Layer urethane from Natural Urethane and a new, stiffer hub give grip in turns with low rolling resistance. For dry surfaces only.

## Who it’s for

- You train on the track or in a hall and compete over short distances, where acceleration and manoeuvrability mean more than top speed.
- You skate technical, twisting routes – including marathons with many turns.
- You have older MPC 90 mm wheels and want a newer design with more durable urethane and a stiffer hub.

## When to choose something else

- Top speed and long rolling in a marathon matter most to you – for that choose the [Enigma 110 mm X-Firm](https://bogdanca.pl/en/mpc-enigma-wheels-110-mm-x-firm-8-pcs.html), provided your frame takes such wheels.
- You skate in the wet – the Enigma is for dry surfaces only; for rain MPC has a separate Storm Surge XGrip series.

## Key features

- **Double Layer construction** — The soft inner ring holds in turns, and the hard outer layer gives speed and low rolling resistance.
- **90 mm diameter** — Better acceleration and manoeuvrability than the 100 and 110 mm sizes in this series – a size for technical tracks.
- **X-Firm hardness** — For dry, smooth and fast surfaces; on cold days and rough routes Firm is better, on a very smooth track XX-Firm.
- **New, stiffer hub** — Together with the new urethane formula it limits energy loss at every push, so the wheel rolls better than older MPC 90 mm models.
- **25% higher durability** — With intensive use the Enigma lasts on average 25% longer than older MPC models, without losing rolling and grip.
- **Mixed sets** — You can combine the Enigma with other MPC wheels, e.g. Enigma at the front for grip and VooDoo at the back for longer rolling.

## Questions and answers

### Who are the Enigma 90 mm X-Firm wheels for?

For racers and advanced skaters training on tracks, in halls and over short distances. The 90 mm diameter gives control and manoeuvrability at high rolling speed.

### How do the Enigma 90, 100 and 110 mm sizes differ?

90 mm accelerates and turns best, so it goes to technical tracks. 100 mm is a compromise between speed and stability for the track and the road, and 110 mm gives the highest speed and the longest rolling, which is why it is chosen for marathons.

### What surface is X-Firm hardness for?

Dry, smooth and fast: tracks, good-quality asphalt and well-kept roads. On cooler days and rough routes Firm will be better, and on a very smooth track XX-Firm.

### Are the Enigma 90 mm suitable for a marathon?

Yes, especially on twisting routes, although track racers choose them more often.

### Can I skate on them in the wet?

No. They are wheels for dry surfaces only. For rain MPC has the Storm Surge XGrip series.
