Among Tni's Revo disc hubs,
only the rear hub for Shimano 11-speed
had been on long-term backorder at the distributor
（the other specs are Shimano 12-speed exclusive and SRAM XDR）,
and upon restocking, the logo was changed and
there were small changes to the freebody specifications,
so it became nominally a different model called Revo Disc Hub II.
There are no changes to the hub body dimensions or price.
Also, the Revo disc rear hub was only available in 24H specs,
but 28H has been added as well.
Our shop still has stock of the original Revo disc rear hub,
so we won't use these new ones until that inventory is depleted.
Since typing Revo Disc Hub II with two full-width capital I's is a pain,
I plan to write it as Revo Disc Hub 2 in this blog from now on.
The Revo disc rear hub we have is around the third batch,
but when the first batch arrived, I confirmed the distributor had
200 units each of front and rear hubs in stock,
and while the front hub was naturally 200 units,
the rear hub breakdown was 100 units for Shimano 12-speed exclusive,
50 units for SRAM XDR, and 50 units for Shimano 11-speed.
Knowing this breakdown, one shop apparently
first purchased a small quantity of the Shimano 11-speed version,
confirmed it works with Shimano 12-speed sprockets,
and then immediately bought up all the remaining 50 units.
Since Shimano 12-speed exclusive and SRAM XDR don't sell that much,
and front hubs alone won't sell without rear hubs in stock,
they kept their front hub orders modest and
were able to treat the distributor as a warehouse to draw from when needed,
monopolizing the most popular Shimano 11-speed hub version
for several months until restock,
thus preventing other shops from building wheels—either generic brands
or 24H rim rear wheels—that would be rebranded under their own name.
A pretty ruthless tactic.
