That is indeed very light. How wide is it and what tire are you able to run?

Are we testing tires or comparing wheels?

Doesn't matter. 500g saves you 3 seconds at 200 watts on a 10% 1km climb. Hardly "way" faster for a 390second climb. The difference is less at higher power.

"In the wind tunnel maybe, on the road way different, and happy to wager before the testing begins which is faster." - you 20 minutes ago.

Make up your mind. I'm good either way :-)

The wheel directly affects the tire choice. As mentioned previously it will affect tubular vs tubeless vs clincher and thus the type of tube (if necessary) then what size tires can be run. That has shown over the past few years to have similar or more affect on speed in the real world.

Hey - I'm just messing with you :-). You have a great disc and it is a good choice.

There are a lot of good choices out now.

This is BS - the Corima tubi is just over a 1000g and the clincher runs 1200+g. Even the track front disk is 900+ grams…what exactly are you showing us here, the track wheel with the hub busted out?

The fastest wheel can be very slow with the wrong tire / tube choice.

Unfortunately not and I was misled by the tech data on their Vanquish Pro RC disc which states spokes: n/a.

Their disc is essentially an RC6 with a carbon cover, not a structural carbon wheel.

I thought you were referring to the rim. There's nothing wrong with spokes in a disc wheel. Why does it matter to you?

Just my 2c on this: I like my disc wheel like I like my (Mexican) wife: LOUD :) The HED discs are dead silent

Because it was advertised as not having spokes yet it does. If you ordered a structural disc and received a spoke and cover disc it wouldn’t matter to you?

No I don't, because filling and spokes are two ways of achieving the same thing. In a disc wheel I care about price, width, aero, and weight, roughly in that order. What's inside doesn't matter to me just as it doesn't matter what kind of filling they use if it's solid or anything else that isn't visible/measurable.

I'll agree showing NA for spokes is misleading, though. That's not cool even if there's no functional difference.

Entirely true IMHO. On that note, the world is shifting rapidly towards wider tires. Zipp, Enve etc are all running 28s on their new wheels but every disk I can see on the market still has a super narrow rim eg. Zipp Super 9 disk brake is only 18mm!

Does anyone make a disk with internal of >20mm? I'd love to have something I can fit a wider tire to (disk brake compatible)

I dont know what the internal sizing is of the HED Vanquish Disc, but they mark 28 mm width to be optimal, check this:

This meets your specs, but I've heard some people having issues with LB discs and needing to return them. It's a good company though, I have a wheelset of theirs on my road bike.

jet disc and V disc, 21 internal.

And the funny part is the Corima road (not track), clincher (not tubular) weighs the same thing as the Premier at 50% more.

I get +1.86 watts up a 4% grade (~360 watts 75 to 75.5 kg 30 kph)

At the same speed i get 4.2 watts up a 10% grade but that's the difference between 728.2 and 724 watts

At 16 kph (~360 watts 75 kg .24) i get 2.3 watts difference (75 to 75.5 kg)

I just received my Light Bicycle disc wheel, having had some reservations based on a couple mentions in the forum.

Aside from some slight cosmetic fiber layup distortions under the clear paint, the wheel is impressively fabricated.

More true than my other top name brand disc wheel.

All still in the 1/2 to 3/4% range, or 2-3 seconds in a 5+ minute climb.

[not intending to disagreeing with you. Just pointing out the relative significance, compared with Mr. Sasso's claim of "way". Where'd he go anyway?]

Yes I understand.

The calculator I created can show difference in watts and it's tedious to find the differences in velocity and time.

I agree, it's not much at all.

I have the Ron Aeron X and I like it so far. It's lightweight (1190 grams), relatively inexpensive, internal rim width is ok (18mm internal 27.5 external, 25mm tire recommended but 28mm can be used, currently using Schwalbe Pro One TT 25), it’s stiff, and sounds just as good as high end discs. I was deciding between this one and Hunt wheels disc wheel but they weren’t in stock. This did take several weeks to be delivered, from Poland. Matt Hansen is sponsored by them, of course he’ll use what he’s given rather than what is fastest so that may not be saying much. It’s also my first disc wheel and only one I’ve used so can’t compare.
