I received a Speed 40C from a customer for service.
They're looking for an inspection.
The image above is the rear wheel, but I forgot to photograph the front wheel overall.
The brake zone is AC3.
Speed's original lineup consisted of only three models: the 40T, 55T, and 40C,
and the 55C was added after rims became AC3 spec,
so there's no such thing as a 55C with a non-AC3 rim.
This 40C has a second-generation rim sticker,
so even from a distance you can tell it's the AC3 spec version.
Incidentally, the first generation came in two types: bright label and dark label (→here).
The rear wheel, but for a Fulcrum stock wheel,
the runout was unusually pronounced.
I suspected someone had attempted a truing job,
but the customer is the original owner of this wheel
and has only used it for about 200km,
so it was probably like this from the beginning.
Fixed it.
Next, the front wheel. When I tried to loosen both axle ends with a 5mm Allen key,
the right end came undone first—a new axle potentially on the verge of failure—so
I applied strong threadlocker to that side and tightened it,
then loosened it with a 14mm wrench and 5mm Allen key
and with a sharp crack! I managed to get the left end loosened.
I applied grease to this side's threads
and tightened it securely to a level where it won't loosen on its own,
so in the future when trying to loosen from both sides with a 5mm Allen key,
there's virtually no chance the right end will come undone first.
