what stem did you pair the bar with if you don't mind me asking?
are there any stem recommendations anyone has that can make a nice stiff alloy combination?
For those rose bars I've used a 120mm deda superbox on my adh, 120mm fsa ns acr on my previous scultura and a canyon v13 (I think it was v13) on my previous endurace. Can't really tell the difference between them to be honest. Rose have a whole range of their own branded stems. You could grab one of those perhaps.
I just bought a -17 100mm kalloy uno stem for my mate who runs the rose bars on his scott addict, but it hasn't arrived yet.
