4 x Rings.
Note: All new footrests come with a set of Rings (and also 2 support clamps). You only need to buy these if you want an additional set of Rings.
If you prefer to buy the Support Clamps these are listed separately.
This listing is just for replacement Rings and not for the footrest itself.
Safety Warning: Please keep the unused rings out of reach of children. The small rings are not a toy and could be a choking hazard.
