This older bike of mine has a Stem Quill style set up for the Handle Bar Mount. I currently have the Stem Quill at it's Max. Height line or Min. Insertion Line, however it is best described. This has left me maxed out on my Handlebar height and I would love another couple of inches minimum.
Specs On my Current Stem Quill Set Up are as follows:
STEER TUBE I/D IS ; 28.6 mm (1 1/8th" inch)
QUILL LENGTH (BAR CENTER TO BOTTOM OF STEM) IS: 100 mm
CLAMP SIZE (HANDLEBAR) IS: 25.4 mm (1.0 " inch)

So just to be clear that is a 28.6 mm inside dimension on the forks/steering tube as confirmed by the measurement on the outside diameter at the base of my Quill Stem. This is an early 90's bike and I have been finding it impossible to find a replacement quill stem that could add some height to my handle bar.

Any suggestion that could get me a few more inches of height are welcomed for this Newbie to your site. This older bike is in really good shape and I am just trying to make it a little more comfortable for some pleasure oriented riding with the Mrs.

Thanks

Oh and I would have added a small pic with this post but as a Newbie it will not let me until I have 10 posts logged
