Any thoughts on Zipp 1080 v disc?

Been offered one at a good price and was after thoughts on this wheel.
It's non fc if they ever made them?!

I would run it with 808/404 fronts.

I'm a 22-23 mph 70.3 bike split standard.
Hope for a shade over 23 this year!

Not a lot on google/ sites.

Any one had one?

With something like the 1080 you need to start asking "which disc". The 1080 will easily be better than a "bad" disc.

But depends on wind otherwise. Taken from here, the 1080 beats a Sub-9 in some conditions (2011 data).


(1080 is in the light blue, Zipp Sub 9 disk in green)

It would surprise me if a zipp disc doesn't achieve negative drag at higher yaw angles? Even the Zipp 808 per the below achieves negative drag, and all the discs tested achieved the same?

I already have a 808 FC rear.
1080 no faster? ...
it's a rear.. a front would be a nightmare in the wind I guess

Have you thought about the 1080 and a disk cover. Usual story with anything aero is the lack of independent data. But the consensus over on ST seems to be that the provide the same performance at a fraction of the cost. Gives you more options when a full disk might not be necessary.

Only problem might be finding one. The aero jacket you can't seem to get over here and the UK base maker that people recommended (can't remember the name) haven't been accepting orders for sometime as they can' meet demand.

I had great results with a pair of these on 66mm Reynolds Strike rear wheel. Made by a time-trial guy, adding around 435g to my Reynolds wheel and he reckoned they are fine up to 3-4% gradient. I did about 5 repeat runs with/without and gained 2.5% speed on 20-mile undulating routes (3-9% gradient), to my surprise. I used it for IM Wales a couple of years ago and I suspect it was roughly neutral on that course. Bit of a faff putting it on and taking off, but well worth a try at the low price.

Quick question on covers, as I've been debating what to do for Mallorca 70.3 (seeing as I can only take one rear wheel, and covers would give me some flexibility rather than actually taking my disc)...

What do you do to pump it up? Do they come with a cutout on one side (not shown on the ebay images), or do you actually have to pump up before installing? I'm assuming the former?

Sure the ones I looked at had a cut out and you use a crack pipe like a normal disk. Even if they dont come with a cutout, adding one would be easy

I've had one for almost 10 years and can't fault it. Not entirely how much quicker it makes me but it's been a pretty solid reliable wheel, broke a spoke a few years ago which was a pain but other than that all good. Its a lot more comfortable than a disk.
I have an 808 for a front wheel, which I regret. I would have brought a 404 if I had the option again.

I have all three ... 808 404 and 303 apart from climbing on the 303 and the 808 on a windy day there all much of a muchness.
If anything the 303s as a set_feel faster on anything but a dual carriage way.

Just bought a set of Xentis mk1 HM.
What a quality item.

Mrs Mungo thinks I have too many wheels.... I really don't understand that.

Let you know about the 1080?!_____________

Mungo...
Genuine point - do you realise you can just press the "quote" button on a person's post, rather than copying and pasting it? I've spotted you doing this on quite a number of threads, and I really struggle to figure out what is your bit of the post, and what you are quoting from someone else!

I'm not meaning to be overly critical, I just wasn't sure if you hadnt realised you could do that?!

I will try next time Stenard.
I'm no Bill Gates!
Being honest once it gets past three or four... thingy said.. then thingy said...
I loose the plot and it all breaks down.

My other passion is boxing, you can't copy and paste on those sites and the thread seems to work better.

I appreciate the tip.. more importantly how many wheels is too many?

Yes, the ebay ones have a cut-out, and happily the head of my trackpump just about fits in there. Would be a good call to travel with covers for flexibility, if course isn't too hilly and you have the possibility of high winds (although I'd use my disk or covers in pretty much any wind now - it's the front that makes the real difference).

Yeah, I'm weighing up the flexibility, and thinking it potentially makes sense.
I'm in the process of buying a new TT bike, which will mean making the jump to 11sp. Wheelsets are therefore slightly limited.

Bike comes with an old zipp 404 with powertap hub. Weight according to this (as a rough guide) would be 1.1kg. My FFWD disc is just under 1.4kg.

So about 300-400g makes it a bit of a wash in weight, for the added optionality.

The issue is, I really don't need the rear PT wheel long term. I'll be putting my P2M crank on the bike, so will only be using that wheel for the time being for 11sp compatibility. My only other 11sp wheel is a very basic training wheel, and not something I'd really be wanting to use standalone if I considered a disc not to be right choice. So the covers are probably a bit redundant other than for this one race. IM Copenhagen later in the year is a definite disc choice per my current thinking. Ideally I'll be able to swap the 404 for a standalone non-PT version, or zipp 60/equivalent at some point.
