If I were you, I’d definitely choose a wheelset with a lower brand premium; money doesn't grow on trees, after all, and I’d rather use the savings to buy other components.

Inner tubes are available on Amazon; however, since Tagoola may produce its own inner tubes in the future, it has largely stopped selling those from other brands, offering only a small number as complimentary gifts.

Looking for some wisdom from the community. I want to upgrade my wheels but I can't seem to find what I'm looking for.

Here's the spec I'm after:
  45mm rim depth—I ride mixed terrain (mostly road, some rough patches)
30mm internal width—I want to run 32-35mm tires comfortably, not just 25-28mm,disc brake

  I've been riding 28mm tires on 21mm internal rims and I want more. More comfort, more grip, more versatility. I don't want to switch to a dedicated gravel bike — my rides are maybe 85% paved road, 15% rough/broken pavement.Every 45mm wheelset I find has 21-24mm internal width max. The "wide" options like Zipp 303S are only 23mm internal. I found some gravel wheels with 30mm internal (like the Tune Nano Gravel 45) but they're marketed as gravel wheels and some are really heavy.

  Is there a true 45mm + 30mm internal carbon road wheelset out there that doesn't weigh 1,500g+?

  Also — am I overthinking the internal width thing? Does 30mm internal actually make a noticeable difference vs 23mm for a road rider running 32mm tires?

  Curious what you all think.

Yes, that's the one. How did you get it for such a low price? Did you use some hidden coupon?

Have you weighed it? Is this wheelset really only 1200g?
