For me it would be the Apex because when i was a kid and at the point of buying my first real bike ,one came up 2nd hand local to me.
My memory of it is sketchy but im sure it was customized by the owner and with lots of nice bits added to it, i remember he had the bars cut pretty narrow even for them days.
Unfortunately my parents werent for me buying a 2nd hand bike so i ended up with a shop bought Cannondale m200
Ive recently discovered a pic of the m200 .Ill post it up 2morrow
