Abstract text

A hub body for a bicycle wheel has a substantially tubular body extending along a longitudinal axis with a pair of opposite end portions, at least one of which has an annular front surface on which a plurality of housing seats for an end portion of respective spokes are formed. Advantageously, at least some of these seats comprise retention elements adapted to prevent said spokes from moving along a direction substantially parallel to said longitudinal axis in all operating conditions. The spoke is thus prevented from moving away from the hub in the case of untightening or breaking of a spoke during a race, which would compromise the correct operation of the wheel and/or constitute a danger to the cyclists.
