Tange / IRD Needle Bearing Headset

[Greg J]

Hi folks,

Sorry about the cross-post from the iBob list.  But since this is going on my 96 A/R, and Riv sells this (or similar) headset:

I am installing the Tange/IRD headset with the needle bearing in the bottom cup.  I am wondering about the order of the steel race insert (I only have one, although I know that in the Stronglight headsets, there are 2 per needle bearing).

Does it go:   

(1) Bottom cup - steel race - needle bearings - base plate, or 

(2) Bottom cup - needle bearings - steel race - base plate ?

Or did I lose one steel race, which should be on both sides of the needle bearing?

thanks,

I used your #2 arrangement for mine.   The steel race is 'floating" per RBW description:  " There are steel floating races, the bearings are replaceable, it’s just---really, really good. "

I have these on almost all of my bikes. The cups that are installed in the frame are zinc plated aluminum. The steel race goes inside the cups - aluminum will not hold up.

From the bottom:

Fork - Steel fork crown race - roller bearings - steel race - lower cup - frame.
