Anyone know the Min insertion for Felt aerobars

Does anyone know minimum insertion for Felt aerobar extensions on the IA?
Did email Felt, but no reply hence this post.
Thanks

You can PM SuperDave Stossel from Felt, he’s on the site here.
Assuming that the armpad clamp is forward of the base clamp, the clamp for the extension itself is 2.5cm deep.
I would allow .5 or 1cm extra off the back to allow for the end plug/cable run?

Thanks Amy, reached out to Dave.
FYI, details are 55mm’s from the front/engagement of the clamp.
