M:Part Elite Crown Race 30 mm ID Suits IS47 Lower Cup

Question

I hope to use this on a straight 1-1/8" steerer

to fit inside a tapered headtube ( 1-1/8 to 1-1/4 ). The 30mm ID certainly fits, so I am assuming 47mm OD would seat the 45 x 45 bearings. The ID of the integrated headtube is measuring 46.7mm ( a Giant Defy - 1-1/8 to 1-1/4 )

This part fits onto the 1 1/8 inch fork, if you head tube is tapered you need a crown race to suit the 1 1/4 inch lower bearing surely? RT 22/04/2020
