I don't recall suggesting anyone use 11 speed cassettes on a loaded touring bike. Did you suggest this?
You stated, "And 11 is the new norm now days." in saying Salsa Marrakesh's components, a touring bike, are behind the times.
Yes, 11 speed is used by Shimano Dura Ace, Ultegra, and 105. SRAM Red, Force, Rival are 11 speed. Campagnolo Super, Record, Chorus, Athena are 11 speed. Shimano mountain XTR, XT, Saint are 11 speed. Its been 3-4-5 years since 11 speed replaced 10 speed at the upper and middle level of bikes. 11 speed is the new norm for upper bikes. But 10 speed is still common on bikes sold in shops and the internet. Its still very easy to get 10 speed parts at all levels, high and low.
But the Salsa Marrakesh uses 9 speed parts. Its been 10 years since 9 speed was the top. 9 speed is not the prior year model/last year's model. 9 speed is two models ago. Its been replaced twice already. It fits my definition of behind the times for bicycles.
Paddleboy17 does present a good reason for why touring bikes remain with 9 speed. The incompatibility between mountain and road groups. And the fact touring bikes take parts from both the road and mountain world and try to make them interact on a bike.
