# Oysi Inline Skating Chassis frames 281 mm, black

Oysi Inline Skating Chassis 281 mm frames are black frames for aggressive skating, mounted in the UFS system. A large soul groove makes grinds easier, and the low-set centre of gravity helps you keep control on landings. They take wheels of different sizes, so you can set them up flat or in an anti-rocker. With some diameters the soulplate has to be trimmed.

## Who it’s for

- You skate in a skatepark or on the street and grind on rails, ledges and edges.
- You are replacing a worn frame on aggressive skates with UFS mounting.
- You want to switch from a flat set-up to an anti-rocker to make more room for grinds.

## When to choose something else

- Your skates are EU size 42 or smaller — the shorter [Oysi Medium Chassis 257 mm](https://bogdanca.pl/en/oysi-medium-chassis-frames-257-mm-black.html) and [Oysi Medium Chassis 269 mm](https://bogdanca.pl/en/oysi-medium-chassis-frames-269-mm-black.html) were made for them.
- You are looking for a frame for urban or fitness skates — this one fits only UFS mounting; see the [skate frames](https://bogdanca.pl/en/skate-parts/frames).

## Key features

- **UFS mounting system** — UFS is the mounting standard in aggressive skates, so you can bolt the frame to a boot with this system without modifications.
- **Large soul groove** — A wide space for catching the frame on a rail or edge makes it easier to enter a grind and hold it.
- **Low-set centre of gravity** — Your foot is closer to the ground, so it is easier to keep control when landing after a jump.
- **Flat or anti-rocker set-up** — The frame takes wheels of different sizes: four equal ones (flat) or smaller wheels in the middle (anti-rocker), which leave room for grinds and make aggressive skating easier.
- **281 mm length** — The frame length has to match the boot — before buying, compare it with the frame you have now.

## Questions and answers

### Will this frame fit my skates?

Yes, if you have aggressive skates with UFS mounting. Also compare the 281 mm length with your current frame or come with your skates to our shop in Poznań or Wrocław.

### Can I skate on an anti-rocker?

Yes. The frame takes wheels of different sizes, so you can set them up flat or in an anti-rocker, with smaller wheels in the middle.

### Do larger wheels require any modification?

Sometimes. With some wheel diameters the soulplate on the skates has to be trimmed so that the wheel does not rub against it.

### How does it differ from the Oysi Medium Chassis?

In length: this frame is 281 mm, and the Medium Chassis is 257 or 269 mm and is designed for skates in EU size 42 and smaller.

### Can I return the frame if it does not fit?

Yes, you have 14 days to withdraw from the contract (return). The buyer covers the return shipping.
