I have. I think they blew up to 30mm. I think 30s were like 32mm.Tofast wrote:Is anybody running the 28mm tires on rims with inner rim width 25mm? If so how wide are the tires?
also how wide would 30mm tires be on that wide rims?

I doubt you'd find any 28mm tyre less than 30mm on this IW. Most will be 30.5+, the "oversized ones" 31+ mm WAM. Add 2-3mm WAM for 30mm tyres.
Minimum bike categories required in the stable:
Aero bike | GC bike | GC rim bike | Climbing bike | Climbing rim bike | Classics bike | Gravel bike | TT bike | Indoors bike
Aero bike | GC bike | GC rim bike | Climbing bike | Climbing rim bike | Classics bike | Gravel bike | TT bike | Indoors bike

I'd run a 28mm tyre on a hooked rim with 25mm internal width but those Zipp's are hookless so I probably would heed Vittoria's advice and not use that combo.
Any word on roughly when in 2024 the Speed is coming?FlatlandClimber wrote: ↑Sat May 20, 2023 2:37 pmYes, officially Corsa Speed Pro will not arrive until 2024, and tire aerodynamics are definitely a little overrated.
While Swiss Side claims un-aerodynamic tries "destroy the aerodynamics of every wheel", all tests I've seen have put the difference from best to worst (with a given width) of 2-4 watts at 45kph. That difference in Rolling Resistance between a very aerodynamic road tire, and a non aerodynamic TT tire is usually bigger than that.
I really hope for the new Corsa Speed Pro to be as fast as the Veloflex Record TLR, with a tread width and wear rate of the GP5000TT. That'd be amazing.
The 2-4W aero difference seems quite big, depending on speed. The RR difference between GP TT and Speed is less than 1 W, so that would suggest a GP TT on the front wheel would be much faster. And that the Speed is also slower than the more puncture resistant S TR. Makes it seem like the Speed is not a good choice for the front wheel.
That's the problem with etrto advice, it's mindlessly generic with no actual rim, tyre or manufacturer specificity. It's eye wateringly stupid.CampagYOLO wrote: ↑Fri Nov 17, 2023 9:54 amI'd run a 28mm tyre on a hooked rim with 25mm internal width but those Zipp's are hookless so I probably would heed Vittoria's advice and not use that combo.

2-4W is probably a pretty high guess. But 2 watts at 45kph would be offset by the difference in rolling resistance:

Can anyone who also used the “old” Corsa Graphene 2.0 tell me if there is any point in upgrading to the new Corsa Pro if I’m not planning to use a tubeless setup. I'm looking to buy new tires for this season and can’t really decide if I it’s worth to spend double the money on the Corsa Pro.

It's going to be interesting to see if the Crr gains outweigh the aero losses from not having siping like on the GP5K TT TR.
