Another day working on wheels (and so on).
I received a rear wheel built with a Stans Crest MK3 rim from my watch mentor.
It was built at our shop some time ago,
but the rim has started cracking, so we decided to replace it.
This rim had an original factory sticker, but in addition to that
it also had an optional cosmetic sticker applied.
The currently available Crest is the MK4, and the differences from the MK3
are that the rim width is wider both inside and out,
it's an offset rim, and it's heavier.
Stans' MTB rims progress from narrowest to widest as:
Crest, Arch, Flow, Sentry, and Baron.
With each model change, the rim's inner and outer widths increase,
so the current Crest is roughly the same width as the previous generation Arch—
in other words, the width associated with each model name has shifted.
I was thinking about rebuilding this Crest MK3 with an MK4,
but there's a reason I can't do that.
You see, this wheel is shared between 29-inch MTB and
cyclocross,
and when I put a new IRC Sylar CX tubeless tire on the Crest MK3
and inflated it to just under 2 bar,
the tire's lateral width becomes around 33.5mm,
which is not barely safe but actually out of spec—
a regulation violation.
So I'm mounting a 30C cyclocross tire with a bit of tension
to keep the tire's actual maximum lateral width within 33mm
for cyclocross use,
but if I switched to a Crest MK4, that option wouldn't work anymore.
So this wheel's fate was undecided until
the customer found a rim for us.
A Crest MK3 with gray sticker spec from the factory
is quite rare.
Plus it's light. Generally it's already a light rim,
but this is an especially light example.
They asked me to make this rim cosmetically similar to the original Crest MK3,
but I didn't have enough sticker inventory,
so I'm going to achieve a similar look
using Grail MK3 stickers instead.
The original wheel's nipple colors don't follow
a rainbow pattern (VAS pattern),
but rather follow the rule of matching
the sticker on that section of rim.
Between the Crest MK3 and Grail MK3,
the relationship between a certain color's sticker position
and the rim holes changed slightly, so I've made some color
adjustments during the rebuild.
Rim move in progress...
Built.
