Not so bad for $900 I think. I don´t really care about ceramic BS anyway.

With the wheels at that price, why by the new ones?

Once you start getting wider tyres, it makes the system weight heavy and then acceleration becomes poor. I can't think why anyone would want to unless it's pan flat and they never need to accelerate.
There is a big jump in weight between a 23mm tire and a 28mm tire.
Rotating weight impacts feel a lot more than real performance “as per the physics” (cause feel is also part of the performance…).CarlosTheJackal wrote:Once you start getting wider tyres, it makes the system weight heavy and then acceleration becomes poor.

You could have 100g extra on a tire and the measurable performance difference on an full 0-40kph acceleration is few cm.
Some people need 28mm tires (a lot less than many think) when you have poor roads. Not the majority that ride on normal roads (definitively not in many US or UK places).

At a real-world weight of 205-210g, my 25mm GP5K TT TdF Ltd tires are the lightest I've ever handled and only the new 175g Veloflex Record TLR are lighter. On my Ascent Polaris wheels, they measure in excess of 29mm with adequate tread coverage. It's almost the perfect tire for that rim/wheel...if it were 30mm even, that would get rid of a small lip/ledge at the tire/rim interface.
And out here in the real world, I'll take the extra suspension when racing for 100mi worth of mediocre to shitty roads...or the one missed pothole. An extra few grams (coming from where though? I'm using 25mm tires...they just measure 29mm) is only going to matter to an infinitesimal degree and only for a few short moments in a race, not the whole thing. It's the same reason why I race on a Madone SLR with IsoSpeed, and why I use a medium padded saddle vs a lightly padded one.

Why is the comparison between 23 and 28?
The old model (26.5mm wide) is perfect fit for 23mm tire, and 25mm tire is acceptable.
The new one (28mm wide) is perfect for 25mm tire, and 28mm tire is acceptable.
So a fair comparison is either 23 vs 25 or 25 vs 28.
Not 23 vs 28...
And for context,
gp5000 23mm : 196g
gp5000 25mm : 221g
gp5000 28mm : 235g
A change from 23 to 28 would be 39g weight penalty per wheel. Assume rider+bike weight 60,000g (60 kg). That'd be 0.066% weight increase per wheel, or 0.13% for two wheels.

Can't escape the truth; I've lost infinitely more races than you've entered.
What matters is I’m out here racing my equipment (in addition to the shitposting) and I’m absolutely using that gear to make up for a lack of physical talent against riders less than half my age. Personally I think I had a pretty great season.

To make it clear, is there any consensus about best tires for both 2020 and 2023 Hypers taking into account 105% rule and lowest possible rolling resistance?
If I read correctly, with a toroidal shaped rim, its not the width of the brake track that is the important measure

On my 2021 R/38, on the front I have Conti 5000 in 23mm which measures 25.2mm, on the rear, Conti 5000 in 25mm which measures 26.5mmC36 wrote: ↑Sun Sep 18, 2022 5:04 pmMeaning that from an aero point of view it will be too wide for the rim. The 25mm in front will be better from drag and side wind stability.KalleWirsch wrote:I´ve received my Hyper 2023 R45 in the meanwhile.
FYI: A Conti GP 5000 (non TLR) in 28mm measures exactly 28mm on the rim. Spot on
Surprised your gp5k 28 measures 28 on this rim when my 25 measures 27.5+ on a 19c hyper 50 rim…
Best I can tell the 23mm on the front nicely meets the 105% rule

Its also worth noting that tyres grow as they get older. One of my wheelsets has a 4000/25 with ~4500km and its grown about 1mm in width

We should specify if talk about official or real width… well, in absolute we should only talk about real width, that’s the only that matters.Hexsense wrote:Why is the comparison between 23 and 28?

If we follow the 105% rule (that is not an absolute truth, more an observation) then the 2021 gen (26.4mm) should fit with 25mm tires, the 2023 gen 27.6 should have 26mm tires, not 28mm.
Installing a “real 28mm” (that in most of the cases will not be achieved with a 28mm tire) will already have an impact on side-wind condition, very significant on the older gen and probably also on the newer one.

Is the Hyper 65 toroidal or not? Do we even have the rim profile shape drawing? I asked Winspace support about that, but they replied ´´they don´t have it´´SixThirteen wrote: ↑Tue Sep 27, 2022 4:55 amhttps://silca.cc/en-au/blogs/silca/part ... rodynamicschristiancarr wrote: ↑Sat Sep 17, 2022 10:27 pmSorry my bad, I should quote @C36.
