How many gooves needed in handle bars for barend shifters?

Howdy there folks. I'm putting my tourer together and it's come time to choose a set of (drop) handlebars. I'll be using bar end shifters and I noticed they characterize handlebars with single groove and double grooves. Which ones do I need?

well, we can do the math right now. cable from bar ends=1. cables from brake levers=1. 1+1=2. ah ha! you need two grooves! if you are running non aero levers, you only need one groove. generally, things are much simlar then they seem.

Bar end shifter cables are not designed to seat into the grooves as drop bars do not have grooves down at the drops. Bar end shifter cables usually exit out of the bar tapes way before reaching your brake levers. That's standard installation for these shifters.
You need a single groove if your brake levers are aero.
Double grooved bars are primarily designed for Campy Ergo shifters.

Respectfully disagreeing, here.

Double groove handlebars are designed for Campy ErgoPower shifters which run both the brake and shifter cables under the handlebar tape. The grooves both run from the lever toward the stem.

Bar end shifters run the cable under the tape, but usually only along the bottom of the bar until it curves upward. I don't know of any handlebars that have a groove in that location.

Bottom line: you don't need a double groove handlebar for bar end shifters. The second groove won't do you any good because it is in the wrong location. It won't do you any harm either. You want a single groove bar but could effectively use either.

Edit: I was respectfully disagreeing with Phatman. I respectfully agree with Fixer who posted faster than me.

I am not aware of any shifting and/or braking system whatsoever that =requires= any grooves. Single grooves offer some degree of convenience for STI and aero brake levers. Double grooves offer the same kind of convenience for Ergo. Bar end shifters don't factor in to it.

I use grooveless bars on my Campy Ergo equipped bike and on my other bikes with various non-aero brakes and shifting mechanisms.

Oh, and one more thing: You probably =don't= want double grooves. Unless you fill the unused rear groove with something like empty housing they can be uncomfortable.

To sum all of this up:

Need: None

Want: Single, but only if it comes on the bars that best fit your body and wallet.

Don't want: Double, but you can live with it if the best bars for your body and wallet have them.
