I received a pair of Bora WTO rim brake front and rear wheels from a customer.
A pair consisting of the WTO45 front wheel and WTO60 rear wheel.
Like Fulcrum's Speed 40 & 55, etc.,
the fact that Campagnolo/Fulcrum complete wheelsets are sold as pairs
with different rim heights front and rear—
as far as I know, only overseas mail-order shops from a certain permanently neutral country do this.
The current owner is the second owner and requested an inspection,
so our shop is serving as a relay point from the first owner.
That is to say, this wheelset has never actually been handled by the current owner.
There are faint traces of sprocket mounting on the freebody,
so it's been used to some degree.
In other words, this isn't a proxy purchase through an overseas mail-order shop—
the first owner also has usage history with it.
The left and right orientation of the AC3 treatment on the brake zone was correct.
The rim was shifted to the right side.
↑About this much
The customer requested a new axle catastrophic failure prevention treatment,
so I did that.
The right end bolt, which should have been generously coated with threadlocker,
loosened first.
I managed to remove the left end.
I applied even stronger threadlocker to the right end threads,
applied grease to the left end threads,
and tightened it just enough so it won't loosen later.
So going forward, with a 5mm Allen key on both ends,
the right end shouldn't loosen first, I believe.
I centered it.
There was some slight wobble as well.
Next, the rear wheel.
When I shook the rim, there was a considerable amount of foreign material that made noise.
↑This balloon-like debris
won't fall out just by shaking the rim, so
I picked it out with tweezers.
Almost no wobble and initially spot-on centered,
but the spoke tension was soft.
It clearly falls below the lower limit of the shipping standard wobble tolerance.
I'm wondering why the previous owner let go of this wheel—
if it was something like "I switched to a disc brake bike," that's fine,
but if it was something like "I bought it but it doesn't seem to go as well as I thought,"
that would be a real shame.
Because that assessment was based on the misaligned front wheel and the slack rear wheel.
So first I increased tension on the freewheel side.
Naturally the rim shifted to the right.
You might think "this much?",
but the fact that we're increasing tension on the freewheel side of an off-the-shelf Bola at all is unusual,
and considering that the freewheel side has less lateral rim movement per nipple rotation than the non-freewheel side,
this is actually quite a bit of increased tension.
I centered it by increasing tension on the non-freewheel side.
There isn't a single nipple that I left without tightening beyond the original.
Just to be clear, I didn't randomly over-tension it—
I just brought it up to about the upper limit of what's possible for an off-the-shelf wheel.
I've also left some wobble correction margin in the direction of increased tension.
