A customer dropped off a Zonda rear wheel with us.
One spoke on the freewheel side broke during riding.
The broken spoke is jammed in the nipple that fell inside the rim,
so this is a spoke fracture on the nipple end
(not a nipple fracture or spoke neck break).
↑Right here.
The spare spoke part numbers for the previous generation Zonda were
three types for front/rear right/rear left:
WH-016/018/019ZOC.
ZOC stands for ZO Zonda, C clincher.
017 was skipped because it's for disc brake front wheels,
where left and right have different lengths—
front right is 016, front left is 017.
For the Bora One 35DB,
front left combined with rear right/front right/rear left are
WH-017/016/019BO35DB,
and since there's a shared spoke, there are three lengths total,
but you can tell that 016 is the number for the front right spoke.
Anyway, the current wide-rim Zonda spokes have
their hundreds digit advanced by one to
WH-116/118/119ZOC,
and for this repair we need rear right, so it's WH-118ZOC.
With the wide-rim transition, the nipple spec also changed—
the spoke thread length was extended just enough to reach
where the nylon anti-loosen insert is embedded,
making the spoke slightly longer,
but the rear right spoke also changed shape and now has
the same butted dimensions as the left, making both sides equal diameter.
My guess is this is a weight reduction measure
to keep the wheel weight roughly the same as narrow-rim wheels,
despite the heavier rim from the wide-rim design.
All fixed.
We have spare spoke inventory for either Zonda generation.
