Bar End Shifter Inquiry...
Hey all. I have a bar end shifter question. Can I use a shifter designated as a "10-speed shifter" in friction mode with either a 9-speed or 11-speed cassette? I'm building a TT bike and I want to place a 10 cassette on it, but I may go 9.
Thanks!
Thanks!

The Shimano SL-BS79 is index only, IIRC.

Yes, thank you. I have a bar end that can use both index and friction. As I understand it, if I use the shifter in index mode, it must correlate to the numver of cogs in my RD. So, if my shifter is designated as a "10 speed shifter", than I can only use an RD with 10 cogs. That my understanding.
My inquiry is whether I can I use that same "10 speed" shifter in friction mode only for 9 and 11 cog RD's? Thanks!

Thanks KCT. So my theory is that if I use a bar end in friction, I'm probably not going to want a RD with more than 10 cogs. The reason is as you point out: the cogs are closer together and your really have to "feel" the shift through. More room for a mis-shift or rubbing. I train on a TT set up that uses a 9-cassette and a Sora RD. It works very well. And honestly, I'm not taking on any mountains, so why would I need an 11 or 12 speed set up? I recall racing around like a nut back in '84 on my Schwinn 10-speed. I really have no need for a 24 speed!
But I may want a 10 cassette, as I may go to a 1x10 set up.

With the bar ends in friction mode, switching betweendifferent speed cassettes is easy and fast. I use 6400 levers in friction with a 12 speed cassette, 11-34, and 6500 derailleurs front and rear. Rings are 46-34. It is a short lever throw for the 12 speeds, but once I got used to it, shifting is very good. I have run 8 thru 12 speed cassettes of various sizes with little or no adjustment necessary, other than chain speeds and link number.
I could go to 10 speed indexed easy enough, I have the components on hand, but like the versatility and low maintenance of the bar ends.
This all on a Poprad that is my multi-use bike.
And I had a different bike withe same set up, but 1X with 44 and 11-36

Okay, getting lots of good info here. Just checked my little "stash" of parts and found that I have a brand new Dura Ace bar end shifter for the FD. Just need a shifter for the RD. Like I said, I'm partial to a 10-cassette, but willing to take advice and move to an 11. With that said, I have an opportunity to get another Dura Ace for the RD, marketed as a 9-speed shifter, or a Microshift 10-speed. Which one is more desirable, if there is an appreciable distinction? Again, I'll be using friction. Thank you!

I am about to replace the bar ends on my touring bike. I have DA now. I have read great things about Microshift. I’m going to go with them if the LBS I have a $200 gift certificate for can get them.

Given the choice between dura ace and microshift bar ends, I’d go with dura ace. The microshift are ok, but develop slop after awhile that makes the indexing not so crisp compared to the DA. If you plan to just use friction mode, I wouldn’t sweat the difference much.

Thanks. I was looking at prices for the DA 9-speed bar ends last night. Not as expensive as I thought, so I’m going to stick with them. They are what I have been used to for over a decade, and they have held up reasonably well despite being subjected to tough conditions while touring.

Yes, I have DA on my main TT training bike and it works really well with a 9-speed cassette, in friction mode. The set of shifters was really reasonably priced also, new. They'll likely outlast me, so a good investment. It's just that they are 9-speed shifters and I'm building a bike with a 10-speed cassette. But it's my understanding that I can use the 9-speed DA in friction for the 10 speeds.

Shimano had 2 models of 10 sp barends, SL-BS78 has friction, BS79 is index only. The 11 speed is also index only.
