Vector m30-p cranks have a super-stiff, cold-forged, 30-millimeter, 7075 aluminum alloy, praxis M30 spindle that fits frames with European bottom brackets, paired with the same oversized, hollow-forged arms and 104 bed spider as our Vector M35 cranks. An independent test lab compared a wide range of cranks to both the Vector M35 and Vector m30-p cranks. Both vectors proved to be stiffer than anything on the market, with the m35's coming in at about 10 percent stronger than the m30-p's.
