• That's exactly what I thought when I first saw them and why I think they're s bit weird, I guess they're in a place where the taper is engaged enough and it just stops things going a mm or so too far. I think I've fitted cranks that reach torque specs before hitting it so it's more of a backup than anything else. Square taper is a bit shit anyway.

  • I've never had a problem with square taper, and like the ability to vary spindle length, but seen plenty of disasters with cranks being wound on too far by people beasting the crank bolts and butchering the tapers.
