Is it ok to lift a road bike by one of the aluminium seat stays? Yesterday I realised I was doing this when inspecting the rear derailleur during a ride (front of the bike facing down, all the weight on one seat stay) and afterwards it got me a bit worried that I might have bent/damaged something. Bike is Cannondale CAAD12, total weight around 9kg. Just have no idea how strong these seat stays are and what they are capable of. Thank you for your answers :).
