Our triple tandem has a 1 1/4" Chris King threadless headset, and a looooooong stem that I can no longer captain. I find plenty of 90 mm adjustable stems that would do the trick, but they are all 1 1/8". I figured the solution would be simple, a 1 1/4" to 1 1/8" adapter/riser, and between that and the adjustable stem I could ride as verticle as I deemed neccesary.
Searched at least 10 pages of Google hits, and found nothing.
Am I going to have to fabricate a custom stem, or is there another simple answer I am neglecting to think of?
