Another day with wheels (and so on).
A customer brought in the front wheel of an R-SYS.
This is the final generation of R-SYS, which was discontinued without ever getting a wide-rim version.
With current Mavic, they've also discontinued
Zicral-type aluminum spokes, carbon spokes,
and things like Exalite.
The rear wheel for disc brakes uses tangent lacing on both sides,
but the rear wheel for rim brakes uses what we call Isopulse—
that's freewheel-side radial lacing with steel spokes.
No matter how much it's straight spokes,
I don't think freewheel-side radial lacing is a good idea...
Shimano doesn't do it anymore, and neither does ZIPP.
The rim had been deformed by buckling, and they'd been riding with it bent back into shape,
but they wanted to replace it with a rim.
They have a spare rim and want us to rebuild the wheel with it.
Based on the price tag that was on it (¥46,200),
it looks like it was purchased from a Japanese retail shop rather than overseas mail order,
but didn't the shop ask the customer who bought just a rim
"So where else are you going to have this swapped in if not at our shop, a Mavic dealer?"
By the way, the customer is from outside the Kansai region.
Got it built.
It's the same rim,
but cosmetically this one looks to be from a later generation.
Going back in the timeline a bit,
one of the trap rings was deformed, so
I replaced it.
The first-generation trap ring—red and without any cutouts—
is retired as a reference item, so we don't use it.
It's possible the customer did this, so I won't be harsh about it, but inside the hub
there was calcium soap-type grease (probably Shimano grease)
smeared all over places where it made no sense.
When I disassembled the wheel, I cleaned the hub body.
Currently, I'm applying silicone grease only where needed,
between the spoke head and the trap ring.
The QRM SL uses a quick-release style hub with a right end and
instead of threading between the right end and left end,
it uses a simple push-on end—and the groove on the left push-on end had "3" grooves.
For the meaning of the groove count, please see (here).
By the way, even now if you press both ends with your thumbs,
there's a faint clicking play.
If you're going to do something like this, I think the wheel price should include
spare left ends as well, and all different sizes should come with the wheel.
If someone asks the manufacturer now to sell them a 2-groove or 1-groove left end,
would they even have inventory?
I did weigh the rim before and after the rebuild this time.
Of course, I'm not telling the customer.
↑wow, that's pretty cold of me
Sorry for the wait! Please take a look at this image!
The original rim!
The rim after rebuild!
↑oh come on, stop it!
