    Suitable bottom bracket for SR Apex crank set?

    I have an SR Apex crankset that I want to fit to my frame (Holdsworth). Can anyone tell me a sealed bottom bracket that will work with these?

    Apologies for the vagueness - The cranks have square holes. The frame has English threads (with the bottom bracket part being 68mm, I think) and the dropout OLD is 126mm. If it helps the there is also a "78" and "B" printed on the cranks.

    Iím planning on creating a single speed. Iíve got 2 spare backwheels knocking about Ė one with a screw on hub and one with a shimano freehub. Would any other info help?

    Hi jiffw,

    It's a while ago, but did you eventually find a BB and what chainline did it give you? Any help is appreciated!

    Greetz,

    Sakae Ringyo made a bewildering variety of cranks under the "Apex" name. Which one do you have?

    It fits two chainrings, has 144 BCD, the arms are fluted, 170mm long and have square taper holes. Not sure wether they're JIS or ISO though...
