Some people use s-bend chainstays for road bikes, but these have more bend than would be required for that. These appear to be for an all-road or mountain bike.
i also guess that the chain-stay is for a big with bigger tires. To me it looks exactly this way. I get the same impression as you do!
the question for me is - do we need to bend the tubes in the chain-stay.
for some kind of bikes - it seems to be obvious or mandantory - (eg for bikes with bigger tires perhaps) but if we take street-bikes - i guess that the tubes are very often just straight - aren īt they!?
i can second your statement: "These appear to be for an all-road or mountain bike"
i have the same impression!
greetings
