Im happy with IGH, I Had a 3 speed on 1957 ... The slight pause in pushing, to let the Gear shift ..

Not wanting to do that says more a bout the Rider than the hardware .

Shifting under power on derailleur drive trains is hard on equipment too .. Results are broken Chains.. Etc.

so even on my Derailleur bikes , I let the shifting from one cog to another happen in the least force situation, rather than Force a Shift, ... Anticipate..

Its Touring, not Racing..
