I currently have just normal drops. I think its a 140mm opening. But with a normal curve. I know salsa makes all kinds of variations of this bar. Actually everyone makes a bar like this and they are all the same, ergo hook part with double grooves.

The part I am wondering about are the grooves. This will be going on my steamroller and I do have a front brake that has a canti style lever. Are the grooves going to be annoying or make the tops not comfortable?

And does any have bars like this or a close style and can comment on how comfortable riding on the ergo part of the hooks are for long rides?

Thanks.
