Fitted my custom 53mm one today, had to ream 0.5mm off the steerer bore to get it to fit over my carbon steerer but then again that is a bit tight on everything, fitted perfectly on alloy steerers. Very pleased indeed thanks @mdcc_tester
Should acetone that stem and just leave the one Pro up the right way :)
I would have if it weren't Laser etched
