Are 28" wheels same as 700c?trijunior

I am looking at a new TT bike, checking out the Pinarello Crono, noticed under specs it was listed as having 28: wheels.
No. 700c is close to 27", not 28. nmKG 361

28" is listed as 700c for road bikes and TT bikes. IF it is different, why is it not on the model above the crono, the montello, and why is there a 700c campy ghibli disc, as they campy doesn't make a 28" disc.

old tire sizes are a bit like measuring a 2x4 (nm)laffeaux

Pinarello Chrono uses 700c wheels.....russw19

The problem is that something is being lost in the translation. Yes, the Pinarello Chrono uses standard 700c wheels.

But if you want to be technical, no, not all 28" wheels are the same as 700c. Take a look at that chart you posted a link to. It shows it better than I can really describe it. There are a few outdated tire and rim sizes listed on there, and some wheels that list as the same size (700a and 700c for example) but the tires for these are not interchangable.

But back to the Pinarello, it depends on what they are measuring, but they are trying to tell you on the website that it is a 700c wheel, not a 26' or 650c. The problem is that someone's Italian to English is not that great, but it's still way better than my English to Italian.

I know that old 700 tubulars were often marked 28x.75", and some cheap chinese hybrid tires are marked 28x1.5", but usually the 28" moniker is reserved for those old English Roadsters that used the big 635mm rims, rather than the 622mm rims used on a "700" tire.

The Euros have long used the "28 inch" designation rather than be specific about sizes. Go to Sheldon Brown for details.
29ers use 700c wheels though...NatC

700c wheeled mountain bikes are called 29ers. I don't know that much about them though.

Actually, the 29" designation is due to the size of the tire not the rim. They all use 700c rims but there is a 28"er and the 29"er uses a bigger (taller and usually wider) tire.

I do not believe any rim is 26", 28" or 29" but they designate them as such based on the size of the tire mounted to the rim.
