I have a Klein attitude with a too long BB spindle.
I now ride with MT60 cranks because the beautifull M900
cranks that were on it when I bought it distorted sadly
enough the chainline.
So guess what, I am looking for a 110mm spindle
but I am a bit reluctant getting the thing out, because
it is in perfect play-free working order right now.
I will contact Carsten, think he might be a Klein specialist
To ask him whether it is worth the hussle.
Can't help you with the other stuff, the guy who sold you
the frame should still have them?
