Looking for suitable mudguard, based on tyre size Will my bike (tyre size 700 x 23) be suitable tobe fitted with this mudguards (universal 28” &amp; 26”)???

Thanks all.
Yes.

A 700c rim with a 23"mm tire is under 28" in diameter. The max tire width is specified at 40mm.

The "28inch" spec is a bit confusing as it's not a common wheel size (700c, 29" etc). I'm guessing a 700c rim with a 40mm tire is about 28" in diameter.
