Sooo stiff and the metal is quality. Huge ring and 41-42 chainline do-able.


No one has proper install instuctions and it will destroy its bb if you don't dial it in.

The crank looked grt and the bb seemed to fit on the axle nicely (very snug at the drv side) and the frame was faced and we measured it at 66.5mm finished size. The first install was to Park Tools specs, w/68mm final size achieved by adding a 1.5mm spacer on non-drive side. That was only pedaled for two minutes in circles outside before play was noticeable at non drive side, people had mentioned this on reviews and had to over tighten or re-install nd side four or five times(recommended by Park also) so I retightened and pulled the arm then re-installed it after re-greasing. The problem was still there and it was going to flex around through each stroke, so I installed a 1mm spacer on the drv-side and bam it pressed the left arm right against the metal compression sleeve of the non-drive side cup w/proper tension. The drv-side arm has its dust seal sitting perfectly in its resting and not making contact with the vertical side of the seal. And no more play! My theory is that the expect you to have a painted 68mm or 74mm bb and that .5mm on each side will build just fine, but if you face your frame and want perfect install try 1 extra millimeter and see if it does not fix your problems. The chainline is Pefrect and the cranks ride great! New bike parts are gettn a little crzy.
