I have 27" wheels on a few of my bikes. Are they any better or worse than 700c ? Not to me they aren't. I have no trouble finding nice tires for 27" wheels and they look great on my large frame bikes( I take a 25" frame). I have no desire to replace them for 700's . The 700c wheels are great too , I have them on a few of my other bikes. I don't change tires that frequently unless they are worn out and I rotate through a few bikes so tires last a while!
