Bar end shifters: Touring type same as Time Trial type?? Help..

Hi,

I am in the process of building a Miata 215 and would like to use bar end shifters (shimano). I'm a little confused as when I look at descriptions in Ebay I see lots of Dura Ace bar end shifters for use on time trial bikes... What I need it the type that attaches to the end of a common drop bar. I could go 10 speed or 8 speed... I have running gear for both.

Are these two types actually different? Can I use the time trial type on my drop bars?

Thanks for any help.
Paul

These are Dura Ace 10 speed Bar-end shifters. These can be switched from indexed to friction. Not all Dura Ace shifters can operate in both friction and indexed mode. I keep the rear shifter indexed and have a ten speed cassette on the bike.

Thanks for the reply. I need to know if those shifters are the same type that the time trial folks use at the end of their bars.. the ones that point straight forward... Still confused.

Dura Ace bar end shifters are Dura Ace bar end shifters. Unless they're Di2, then they're the same thing.

That's what you want, what's pictured above.

They are. What drivetrain do you have? 2x9? or...?

Yes. Bar-end shifters are bar-end shifters. I've used mine on drop bars, recumbent handlebars, and straight bars. Same shifter, no problem.

+1, quite right. You're mission is to buy the one appropriate for your rear cluster (eg, 8-, 9-, or 10-speed), unless you're a straight pimp, and you intend to go friction (any shimano bar-end shifters currently on offer are friction-compat, with the exception of the Di2 stuff, which makes my head hurt when i think about it). In the waaaaaaaaaaaay back years, they made 8-speed dura-ace bar-end shifters which had a different pull ratio than all the other shimano groups. Many retailers tend to sell the bar-end shifters as "dura-ace", even though they're actually non-series. Someone will almost certainly post on this thread about "beware of the 8-speed dura-ace; they won't work with anything but an 8-speed dura-ace rear derailer", which is true, but you won't find any of those shifters unless you go looking for them specifically.

Careful- Shimano's thrown a "gotcha": the SL-BS78 10-speed bar-end shifters have a friction option, the SL-BS79 10-speed bar-end shifters do not. Don't look at me, I just report this stuff.

Thank you all. Appears that I'm worried about nothing. My options are either 8 speed cassette with a three ring crankset or a 10 speed, also three ring crankset. I am assuming that the front lever will have enough range to handle a triple.

I am leaning toward the 10 speed as my derrailers are fairly recent vintage 105 with a long cage rear derrailer.

Again- Thanks!

When I bought these they came with cable housings and down tube cable stops.

I've run shimano bar-cons with triples, both with road FD/triple crank and mountain FD/triple crank. Plenty of throw for all the normal stuff.
