Touring, triple, bar end friction shifting. the 16t jump from a 24 to a 40t , even with out the newer ramped and pinned shifting features
when I upshift , I do that at the crest of the hill, where I am able to remove the strain on the chain, when climbing ,
then the rise up to the middle chainring goes well , in a reasonable time period,... though not like an electric switch ..
though the gear change of the internal gear in my Schlumpf * Mountain Drive crank is significantly quicker , the chain is not shifted ,
the internal reduction gear is engaged , then a 50t then acts like its a 20t. as the crank turns faster than the chainring .
*the companies over drive, speed drive, version is a 1.6x , so a 34t acts like a 54t,then, chainring turns faster than crank arms .
