I’m restoring a 1987 Miyata 112 and while taking apart the headset, I managed to crack the crown race. The 1987 catalog simply refers to the headset as “Tange Sport” which hasn’t been helpful. The crown race has a 27mm ID x 36.5mm OD x 7.25mm height.

I did manage to find a very similar replacement on Ebay. The description states dimensions as 27mm ID X 36.2mm OD x 7.6mm height while also having a small lip on the bottom. Is this crown race a viable option? If not, can you point me in the right direction.

  1. Might be tough to find.

    FYI I rode a 105 headset that I eventually realized was cracked for a long time. Never knew.
