This preload bolt is a direct replacement for the original one that came with your Shimano crankset. It comes equipped with a tough 6061 aluminium build to prevent any axle crushing or ovality, while its longer thread prevents pull out. Another highlight is its smaller flange diameter, which ensures that the arm clamps the axle and is not restricted by the cap. This is a stronger replacement than the genuine Shimano bolt which comes as standard in your crankset. Compatibility: Compatible with most Shimano Hollowtech II cranksets including Shimano Dura Ace, Ultegra, 105, XT, SLX and DEORE. XTR - M9XX Series / M9000 Series XT - M8XXX Series / M7XX Series SLX - M7XXX Series / M6XX Series Deore - M61XX Series, M6XX Series, M5XX Series Saint - M8XX Series ZEE - M6XX Series EBike - M8000 Manufacturer's Part Number: BXPLB-BLACK
