i did mine by letting the upper bone drop down to the lower bone, and then measuring in mm the difference from b/j centres. Then measure the height of
the hub and do the trig. Or just believe the people who say it boils down to 21mm. I think it was 21 anyway, that or 25...!

If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Is there no castor offset to consider built into the Sierra hub then ?

not sure about built in castor, but the hub axis is infront of the line between upper and lower pivots, this could be called anti-trail? i
think....
this might explain why sierra hubs dont seem to like self-centering much.
any thoughts?
