Time to re-open a thread that has been dead for a few days. I am facing the same dilemma as miamijim in that I need to replace a dead Shimano 600 tricolor headset on my new Cramerotti. Obviously I have perused the options presented here but I have a couple questions.
1. Crown Race: would my crown race be the same size as miamijims? Or did this headset come with different size races? I presume mine is ISO but I don't particularly want to go to the trouble of removing it to measure if I don't have to.
2. Stack height: as miamijim says it is ~38mm. I like the look of the Velo Orange Grand Cru but it is listed as 40mm stack height, this would rule it out no? Doesn't look like there are any spacers that could be removed to take it down a couple mm's.
