7 speed indexed bar ends

Does anyone (did anyone) make seven speed indexed bar end shifters for Shimano derailleurs? I know I could just do friction, but I'm looking for indexed.

Can't you just take standrad 7 speed indexed levers and get an adapter?

Oh right, duh. Good idea.

Shimano Ultegra bar end shifters - SLBS50 were 6/7 speed shifters

Shimano Ultegra bar end shifters - SLBS64 are 8 speed shifters, but reportedly work with 7 speeds as well. These are still being made.

Supposedly, if you're running Dura Ace, these won't index due to the cog spacer size. Conversely, Dura Ace bar end shifters won't index with non-Dura Ace.

They were made because I have a pair of them on my RB1. Bridgestone included them stock for a couple years before they went to STI.

SL-BS50. It's a Shimano 600 component, which fits with the rest of my group.

Yes, and the person on the big auction site, who happens to be in Portland, sells them for a mint. I've been watching those.

I have some 6 speed indexed levers for braze on, and I got the adapters & put on the pods and they worked beautifully. Only aesthetic issue was the levers looked long.

I had a Fuji Espree with a set of black Suntour barons that had indexing for sure on the rear shifter. I don't recall the model but I'll try to find it.
Found it, Accushift Plus, and they worked very well.

My wife has a Fuji Espree mixte with 8 speed Ultegra shifters and a 7 speed cassette. Shifts great.

The spacing is a little less on shimano 8 speed than on 7 (4.8 mm v. 5.0). Sheldon Brown's Bicycle Frame and Cassette Spacing Crib Sheet
It wouldn't surprise me if that is close enough for a 8 speed shifter to work. It will be a lot easier (and cheaper) to find 7 speed down tube shifters. Also shimano makes 7 speed brifters.

The bike already has 7 speed indexed downtube shifters, so picking up some pods would probably be the most economical route.

I have the same bike with those Shimano shifters and in my stash have a new still-in-the-bag set of the SunTour Accushift.

Do you just leave the last two clicks for the high gear (cable goes slack) so you don't overtension the cable?

No. There are no extra clicks because the derailer is up aganst a stop. You'll have to explain to me what "ovetension the cable" means.

As you know, for a top-normal derailleur, pulling on the cable shifts down. If your set up the 8 speed shift levers so that the highest gear is the first indexed position, you will get to the lowest gear by shifting down through to the 7th index position - one stop is left over. Of course you adjust the High/Low stops on the derailleur, but if you pull hard enough on the lever, could it go to position 8 and overtension the cable? Now that I think about it, I'm guessing not because DT shift levers aren't like the ratcheting system of STI brifters (this can be a problem setting up 7s cassettes with 8s brifters or double cranks with triple brifters).

Do you have a problem with the derailleur going past the largest cog if you pull hard on a friction shifter? Of course not. The derailleur is up against a stop and can't go further. It's the same thing with an index shifter. It does not know that there is an additional click past that point. Think about it. I have the feeling that I've tried to explain this to you before. Am I wrong?

I have several sets on my own bikes, they have been out of production for 15 years or more. I have found them in the form of a complete bike, I do a shifter swap, and I am set. One thing I look for on used bikes is bar end shifters.

One part I tend to stock pile is any vintage bar end shifter. Long out of production, they continue to increase in value and I just like them.

I did, that's why I answered my own question in my response:

Are you my cranky old uncle living a closet life as a cycling fanatic? I love him dearly.

Yup, you explained how to kludge simplex retrofriction DT shifters onto Shimano barend pods. It took me a bit, but I finally wrapped my tape around that handlebar.

I didn't realize that there was a difference between 7 and 8 speed spacing when I put 8 speed brifters on my son's 7 speed bike. That may explain why it was so touchy to get adjusted. Once dialed in, it works great.

I was worried that my Shimano 8 speed bar end shifters wouldn't shift my 7 speed Shimano cassette without the "alternate" cable routing that Sheldon Brown discusses. Was surprised that it shifts beautifully with just normal routing, even when, on paper, it shouldn't. Go figure.

SLBS64 best made. You can flip them into retro. The .2 mm. makes no difference; human hair .18mm. (O.K. a thick one)

Seven and 8 speed are close enough in their spacing that the shifters will work well if mismatched, on the condition that the rest of the drivetrain is set up and everything is aligned, having a Shimano derailleur with it's floating upper tension pulley also helps a lot as it can forgive small deviations.

Running seven speeds with an 8 speed is rarely a problem, the total difference in spacing over the whole span of the cassette is only 1.2mm.
