6112 RRU install questions

[danderer]

I'm installing a 700c with 6112 RRU.

Looking in section 1.3 of the install manual I've got 2 questions.

1. Installing the RRU with a Y2 distance of 13.8" will require major work. I can readily install it with a Y2 of about 9". If the remaining geometry is correct (centered on the shaft and with the arms parallel), if there is adequate clearance when the rudder is hard-over in both directions, is it a problem installing the RRU at 9"?

2. The RRU has a series of holes in the arm - 80mm, 90mm, etc. Does it matter which one I use? I assume I just use the one that maintains the proper geometry.

Thanks.

Should be no problem.

Yes to maintain the Geometry. Ideally you get the best movement resolution the further you are out from the hub.
