Today it's wheels again (and so on).
Continuing from yesterday.
I'm rebuilding the front wheel of the Bontrager Line Carbon 30.
The disc rotor diameter is 203mm...
No, it's 200mm.
There's also a larger 220mm version.
This disc rotor uses 6-bolt mounting, but
before 6-bolt mounting became completely standard,
there was a 4-bolt rotor from Formula
(an Italian brake manufacturer, unrelated to
the Taiwanese hub maker of the same name)
and even the sizes were non-standard—
instead of the smaller 180mm being 160mm,
it was 165mm.
Installing a 24mm shaft crankset onto a 30mm shaft BB
is possible with an adapter since it's only a 3mm difference in radius,
but you can't make an adapter for a 29mm shaft
(claiming to be 28.99mm) against 30mm,
so they released it as "DUB" instead.
Looking at how SRAM lately tries to standardize
rear derailleur mounting ends and such—
their ambition to "control standards themselves"
is pretty transparent, or rather they're not even trying to hide it.
Mavic's UST (Universal Standard Tubeless) standard
for tubeless rims became a true de facto standard,
but the ISO (International Standard) disc brake mounting standard
never actually became international.
Who knows what will catch on and what will fade away next.
All rebuilt.
Bontrager 110 BOOST hub, 28H
Half-comp radial laced in reverse Italian cross pattern.
Reusing the nipples.
I'll do the spoke twisting later.
↑The weight of the front wheel rim.
I'm not publishing the actual measured weight
because I don't think that data adds any value to the article.
↑Here's the measured weight photo of the rear wheel rim too.
If I have matching rims front and rear with the same spoke count,
I usually use the lighter one for the rear wheel,
but this time that's the case just by chance.
I didn't disassemble the front and rear wheels at the same time, after all.
