Are 27” wheels just cooler or is it me?

But there is only about 5mm difference in size between a 27" and a 700c

• you can barely tell the difference.
  
  

The difference in bead-seat diameters is 8mm, but if you take into account tyre sections, then it does make a noticeable difference. Well it would do if you could pump weinmann's (no hooked beads) over 85-90 P.S.I without shitting yourself!

But going back to the original question, yes of course so-called "obsolete" products are way cooler, due to availability (or lack of).

I couldn't drive a post J reg ('92) car anymore, although of course truely cool is pre 72 free road tax!
