Hope MK1 big Un’s and D521 wheel build

[Stretch79]

I built a set 25+ years ago and remember it being the hardest hub to work with. Getting the spokes to seat in the flanges was really tricky. Take your time with the build.

I won’t be rushing these that’s for sure.

I was googling this last week as I have some to build too, I also have a built set (20mm / QR rear) so will be double checking against those as well but I think the numbers in here are close…

I seem to say this almost every time wheel building is mentioned but it’s a hill I’d die on, trusting other people’s numbers is a great way to end up with the wrong size spokes.

I have seen first hand differences in sizes between two examples of what should be exactly the same product in both hubs and rims. I don’t know if it’s manufacturers having things produced by multiple factories, in different batches or what but it happens so I always measure my hubs and rims myself now.
