Seba is short for Sebastien, so it's pronounced "SEH-ba", rather than "SEE-ba"!
This is a replacement part for the cuff attachment found on the Seba High, FR1, Seba Deluxe, GT-90, and Seba Carbon (w/ plastic cuff). The cuff button is adjustable and can hold the cuff in 4 different positions.
One unit contains a single cuff button, plus the 2 washers that it uses.
This part is not compatible with Carbon cuffs or with TriX, FRX, GTX and FR JR skates.
