A customer brought in a Reynolds AERO46 (aerodynamic wheel) for me to work on.


It's got a wide rim, but looking at the weight compared to the tubeless-ready rim from the other day,
considering the rim height ratio, it seems incredibly light for a rim of that width.


Looking at the rear hub, it seems some don't use radial lacing on the non-freewheel side.
Actually, that's exactly why he bought this one.


There's quite an elaborate valve rattle guard design.



↑Removed state
New wheels come with extra rubber of this type, and
I'm sure you can probably buy it separately,
but proprietary specs and custom designs like this scare me
when you think about what happens if the manufacturer stops making them.


Whether it's the hump on the tubeless-ready rim from before or the rim holes on this one,
what is this level of molding technology?

For the inspection, since it's a tubular rim with internal nipples,
I had to check it before mounting the tires.
There was just a slight wobble—essentially no issues.
Since the customer wants to use tubular tires with rim cement,
I gave him a thorough rundown on proper bedding and
all the various procedures involved.
