Hey, so last night after I got back from a ride, I had a coupla beers and did some maintainence on my DJ bike, then noticed a few things I needed to alter on my other bikes, and before you know it there were bikes everwhere and you know the score, but anyway...
I was interested in the exact difference in my chainstay lenghts so out came the tape measure and I started measuring up my frames and before you could say "Stop it you anal fool!" I was writting out a little chart on a bit of scrap paper. In doing so I found something which I thought was quite weird.
On the set ups of my three bikes, a GT BMX, a Giant AC1 and my lovely Revell, totally without being aware, I've set up the cockpits to within less than 1/2" of each other! I suppose this isn't that suprising given that I haven't changed size, but I was shocked at how close the measurements are to each other. I've recorded them to the 1/4 inch on the chart, but they were like less than a 1/8" out in reality. I am stunned by my own ability to set up three different bikes by 'feel' to such a tight tollerance.
Am I a freak or is this common?
Edit: When I measured from the 'saddle', I mean the bit of the saddle my weight actually focusses on, for me normally about 2-3" from the back of the saddle itself - where my hips bones rest if you see what I mean.
