I received a Fulcrum Speed 40T from a customer.
The Speed 40T (tubular) comes in the CULT specification, which corresponds to the Ultra in Bora terms,
while the Speed 40C (clincher) comes in the USB specification, which corresponds to the One in Bora terms.
Also, with the original generation, the Speed 55 was only available in the T version.
Anyway, let's start with the rear wheel.
One spoke is broken.
It's the rim hole directly below the F in FULCRUM when viewed from the freewheel side.
From the broken spoke, counterclockwise when viewed from the freewheel side,
the adjacent spoke on the same side was dented,
and I already knew it needed replacement before starting work.
↑During work, I noticed that a spoke on the non-freewheel side near the nipple was wavy and deformed, so I loosened the nipple.
The fact that radial runout couldn't be fully corrected directly under this phase is also a reason I noticed it.
Also, there was one more spoke on the freewheel side that needed replacement.
With one spoke broken and creating a significant wobble,
I didn't check the temporary center, but
after replacing the spoke and truing both radial and lateral runout,
the center came into line.
It's fixed.
The one that was originally broken is directly below F, so if something got caught during rotation, this would be the second impact.
Usually breakage is more common on the first impact though.
Rather than counting n consecutive spokes on one side only,
having 4 consecutive spokes that needed replacement across both freewheel and non-freewheel sides is quite unusual.
↑Replaced spoke (freewheel side)
↑Replaced spoke (non-freewheel side)
The radially-laced spokes on the front and rear left have a flattened section below the spoke head.
↑This is quite bent, though it's hard to tell in the image.
If you imagine extending the straight line of the threaded section, you'll get the idea.
Actually, until I replaced this one, radial runout couldn't be corrected at the phase of the adjacent spokes on the freewheel side.
Good thing I had spare spokes in stock!
Actually, except for some MTB and road wheelset models,
I pretty much stock spare spokes for everything.
Next, the front wheel.
I forgot to mention this earlier, but
the rear wheel had play in the bearing adjustment, and the right end nut had loosened by hand.
Although CULT ball races are resistant to damage,
I've seen examples where pitting has developed from years of use with play present.
The front wheel also needed bearing adjustment, though not as severe as the rear.
It had no initial hub offset and required minor trueing.
