Another day working on wheels (and so on).
I built a rear wheel using a Kinrin XR300 rim
that a customer brought in.
It's not one of the Nomu Lab wheels #1,
partly because it's a rim the customer supplied, but also
this rim is actually 650C.
In the photo above, I lined it up next to the same rim in 700C size.
On the Tni section there's a crab beam sticker,
Evo hub, 24 holes, black semi-competizione, 4-cross lacing pattern.
Basically silver alloy nipples throughout,
with gold alloy nipples only on either side of the valve.
With 9-speed, the sprocket wouldn't fit partway through,
and with 11-speed, the spline length wasn't sufficient—
this is a Shimano 10-speed "dedicated" freebody design.
There's no way to swap this out for a Shimano 11-speed freebody.
That's because this Evo hub has a hub shaft that's not
the later-model aluminum type with 15mm outer diameter
(↑the Evo Lite hub has the same spec),
but rather the early-model steel hub shaft
with 10mm outer diameter.
Of course, the hub bearing inner diameter is
all 10mm, but if you swap in bearings with the same
outer diameter but 15mm inner diameter,
you still can't replace the hub shaft with an aluminum one.
That's because on the left side of the hub body,
no bearing size exists to make that possible, and
even before that, the bearing span dimension
on the hub body itself is different between
the early and late versions of the Evo hub.
↑The Evo Lite hub body and the early Evo hub
when you line up the right flanges,
the left flange shows this much difference.
There's the constraint of being 10-speed only,
so I asked the customer whether they wanted to use
one I had on hand or buy a new 660 hub,
and they decided to go with the hub I had.
