Klein headtube

[baron von greenback]

Can someone explain to me why some kleins have the bulgey headtube is it just the high end frames certain years or are these the only frames that will take the all in one stem and bars or will they fit the straight head tube kleins

Also the all in one stem bars do they fit mormal 1inch or 118 headsets thanks

Early 90´s top range Kleins forks has 1.5" oversize steerer tube ... and integrated bearings in the head tube, internal cable routing, pressfit BB ... they were very advanced for the time.

There were MC1 (the one piece bar/stem) to fit standard 1" and well as MC1s for the proprietary oversized head tube.
