Rated 5 out of 5 by Anonymous These (M15) will perfectly fit with original shimano hollowtech cranks (with octalink bracket). Just to let you know because i wasn't sure if these are going to fit. And they are even lighter than the originals.
AND. X-tools Allen key 8mm, which i bought too, fits perfectly with these bolts. Fits even better than with the original bolts.
