Why would you want or need a disc for climbing?? Just use the lightest wheels you have.

Should clarify. A HILLY IM or 1/2 IM.

IMHO - HED Black

• It's generally awesome overall, and fast when it matters-- on flats and descent
• Killer brakes for the descent
• Relatively light as disc wheels go
• Wide internal and external, which adds to its general awesomeness
  

Someone change my mind.

Yup. Best of both worlds.

How is that materially different from the way spoked discs are constructed? I have not compared weight, but an Ardennes Black with a disc cover seems like it would be the same as a JET Black disc.

The trade-off is cost for convenience. I chose a disc because I did not feel like messing with a cover. But, if i were budget-constrained, I might have considered a cover on a standard rear wheel for my bike.

No first hand experience be honest... But I have been told discs handle differently, and not so great descending.

If you're worried about weight throw into the mix a tubular disc then

What course?

^^^This.

A dedicated disc also allows you to easily run a race-only tire and latex tube. Personally I run a Conti SuperSonic with latex.....not something I'd train on, and no risk of changing tires/tubes pre race and getting something like an undetected pinch flat.

None of this is essential, but convenience is nice.

This. You'll save more time by braking late than you will lose due to an extra 200 grams.

The new AEOX disc is just as light as Roval but has a textured brake track, so there's that's, too

I’d pricing and braking matter, here’s the lightest weight wheel with aluminum brake track that I know of

https://ronwheels.com/...els/101-aeron-x.html

Renn 555 is slightly lighter and cheaper

According to Frank, the weight for his wide brack track wheel is 1190 grams. Previous generation wheels may be lighter but that’s probably because of thinner brake track.

He's got a wider one? Wider than 24mm?

Here are stats Frank emailed me about 555

Brake track width is 24mm. Inner bead width is 18.25mm
Weight is 1190 grams
Max lateral runout is .5mm
Max vertical runout is 1mm
Aluminum brake track
Nomes honeycomb core with 3k plainweave carbon skin
Aluminum hub 8,9,10 and 11 speed compatible

I've always wondered that. Get the lightest climbing wheels you could afford, then slap on a disk cover. "Best of both worlds", no? Could anyone think of negatives going this route?

In my mind, the Citec 8000 is perfect for that.

It's very light (sub<1000g), and the braking track is aluminum so its perfect for the descents.

It's a hassle to take wheel covers off; you'll need a cassette chain whip to do so. I have had issues with chain rub in the largest cassette cog.

Uhmm, hello... no WHOMP WHOMP sound

The Ultra version is 825g, which is incredible. BUT it has a 20.5mm external width.

Of course there are negatives:
- Doesn't look as nice because it generally has the ugly screws or visible tape
- You'd need to find a very light wheel to make up for the weight of most covers + tape/glue/hardware
- The cover shape won't be aero optimized. Neither flat nor lenticular. If it has screws, it'll have indents.
- God forbid a cover comes loose while you're riding. Less likely with a properly manufactured item.
- The time/effort of getting it just right

At that point, why not get a Ron, Renn, or AEOX?
