I need a new bottom bracket spindle for my vintage Adroit to fit in the Grafton Joysticks cranks. Klein Tech manual says that the spindle length for them is 121mm.

I am interested in ActionTec's titanium spindles that are available in 120mm length and the next one is 122.5mm. Which one of these should I use or am I better off with a steel one in 121mm ?

Yep i'd say the longer length. I had cooks on my Klein. And it was a very long axle for them. I had a ti. Didn't like the flex. When i stood on the pedals i could feel movement. Which is very un-Klein like :D

I'd stay with cro-mo. Kleins are light enough any way:D

I had a set on a bike back in 90. Still have the MRC Ti BB I ran them on and just measured it at 131mm. I ran it on that bike for 5-6 years. Then put it in my sons bmx bike and ran it there a few years and took it out before selling the frame
