I currently have access to four bikes with IGHs. Three Sturmeys and a Shimano. I like them all but
my favorite is the XRF8 that came on my folder. Shifts nicely and has a gear for all occasions.
It's quiet and feels better after 2500+ miles, I hope it never craps out, though I'd replace it with the
current SA IGH 8 speed. My son's adult trike has a SA three speed with the thumb shifters, I have to admit
I really like the ease of the thumb shifter. I was hoping to upgrade his to a five speed but I'm concerned of
the reliability issues brought out in this forum. But I heard worse about the XRF8, knocking on wood.
