A little big
Had to bust out the dremel and a polishing abrasive pad - to shave down a little - I was putting them into vintage Shimano deore crank arms and the outside diameter of those was a bit smaller in the threads - went around with the dremel tool to remove some micro mm’s - all good now and doing their job of looking handsome

Haven’t installed them yet since I’m going to a shop to have them install it, since I don’t have crank arm bolts without the black plastic washers that come standard. Overall, these feel really solid. I’m sure that once they’re properly installed, they’ll make my vintage single speed bike look extra classy!
