Just noticed I've never heard them discussed here. Surly basically invented them and called them the Corner Bars, but given it's "bits of metal pipes" you can get some without the name branding now. They're supposed to give you like a drop bar-esque experience except without changing out all the controls and most likely drivetrain, so if you ever wanted to try one, maybe this is interesting for you. You might have to readjust some cables or hydraulic lines.

I post this here because I feel like "how do I convert my flat bar into a drop bar" is a very common question in the bicycle world and while it is possible, it is often sort of not very advisable unless you like wrenching on your bike
