    Great product but we're to big for the eletrica I have.
    SBP: Not sure what an "eletrica" is but these definitely fit an American standard 1 piece crank bottom bracket.

    Had to modify my Schwinn Sanctuary with a 3 piece crank for fitting a BT80 engine kit. Adapter fit flawlessly and required no sanding or any other modification to fit. Black finish looks great, and all threads were perfectly clean with no binding whatsoever. Would recommend to anyone in need of converting to a 3 piece bottom bracket.
