I received a Cambium (カムシン) bike from a customer.
The rear wheel isn't G3-spoked, but instead has equal numbers of spokes on both sides—a 20H 40-spoke configuration with "ordinary wheel" construction.
The Cambium G3 hasn't been discontinued and is still being sold alongside this version,
but at one distributor the non-G3 is inventory-only while the G3 continues as regular stock.
The front wheel is labeled "asymmetric" as well,
but it's actually symmetric and shared with the G3.
The asymmetry isn't a big deal really—it's just an offset rim, that's all.
If they'd at least included left-right different-diameter spokes,
I think it would've looked a bit more impressive,
but since this is the lowest-price-tier wheel,
there's probably a constraint that it can't exceed the next-step-up Vent model.
I'll write about this in detail in the next article, but the Cambium's rear hub
bearing has evolved from HB-SC013 to HB-SC113,
and while it uses cartridge-bearing construction rather than cup-and-cone,
it now allows for bearing preload adjustment.
（The front hub remains HB-SC013）
On Vent and above models, the front hub also uses HB-SC113 cartridge bearings,
adjusted with a split locknut system.
Previously, hubs at this grade were press-fit style, so
if the hub developed play, the only option was to replace the bearings.
