Hey There, i am fairly new here and i got four words for ya:
Raleigh 20's UBER ALLES!!!!!
No but seriously i got mine recently and tricked it out and modded it fairly heavily and it is probably the best and most enjoyable material possession i have ever owned. I call her Tweeny or Twiggy. I wouldn't give it up for nothing.. well.. ok, if someone offered to trade it for a brand new BF or Brompton or Swift, i MIGHT (stress that) do it. Anyhow i wrote a long and in depth page about it, including many pictures, costs as well as info on a cheap/new way to get a good Bottom Bracket and fork going.
