That crankset doesn't have a listed BB spindle length anywhere. It certainly could be 122 for that style crank. Is there a reason you reject that length?
I just felt like 122 seemed way too long compared to what I remember it looking like.
But ok! According to the specs of my bike, what I need is VP BC-73C, 68x122.5mm, Square Taper
And here it is:
VP Components Square Taper Bottom Bracket - Trek Bikes (DK)
I can't find it in Denmark. Interestingly, on the picture of the item that I linked to above, the part itself only says "VP BC-73;" that is, without the "C" at the end. I do see in some other places, like
here, that it is called "VP BC-73C:"
But I can't really order from outside the EU or it'll become expensive due to import tax.
So I'm wondering what does the "C" at the end mean? Is it important at all, or should I just focus on the 68x122mm part?
And if so, then I suppose I could order one of these (different brand)?
