A customer brought in a wheelset that came stock on a complete bike from a certain manufacturer.
The front wheel had serious radial runout, or so the customer said,
and sure enough, it was seriously bad just like they mentioned.
Without even putting it on a truing stand, you could see the wheel wobbling
just by watching it spin.
Plus, both wheels had this much lateral centering offset.
There was plenty of runout too, and even for stock equipment on a complete bike, it was pretty sloppy work.
But working through it carefully and truing the wheel, it ended up coming out just fine.
The customer confirmed that the centering offset is now completely gone.
The rim is WTB,
and the hub is Formula.
Formula the hub brand and Formula the disc brake brand are completely unrelated—different companies entirely.
（Just to be clear, the rotor in the photo is Magura.）
The disc brake Formula uses a proprietary 4-bolt rotor standard that's 165mm instead of the standard 160mm, which was always a hassle. But at least the brake fluid was DOT 4, which is easy to find. With current models now using 6-bolt rotors in 140, 160, 180, and 203mm sizes, it's become difficult to keep using the old Formula brakes.
By the way, what's unusual about this wheelset is that for a hand-built disc brake wheel, both front and rear are laced Italian-style (3-cross).
