euro bottom brackets have normal bearings in them but they are smaller, The bottom bracket that you need is the same size as the ones that MTB manufacurers use like DMR, Azonic and other cromo 3 pc cranks. Chain reaction cycles sell them and i also think the generic d30 cranks have 20mm spindle I think cyclesports and alans do the D30 cranks. can I have first dib dobs on your 19mm euro BB if you get the frame please.
