Shimano SL-BS50 Bar Ends, no friction

So I picked up a pair of used shimano bar ends, which I thought were 7 speed, but I am only getting 5 clicks (6 speed). I have read through some threads stating that they had a shim that made the shifters a 6 speed, but nothing explaining how to remove this shim.

On top of that issue, the shifter will not go into friction mode. Any advice?

You need to loosen the screw, then turn the dial to friction. Is that what you did?

I don't know about the shim, but the insert has to be oriented correctly (with the tab pointed down, if memory serves) in order to get all the detents to work.

The insert has nothing to do with the click action, the shifter's 7th position (6th click) is normally locked out only by cable tension.

The insert is a curved plastic channel that makes the diameter of the cable spool groove larger diameter, to pull a little more cable to make the derailer move across the more widely-spaced cogs on a 6-speed freewheel.

As for why the OP's shifter doesn't have 7 positions (that would make for 6 clicks), the shifter is almost certainly mounted on the pod at 90 degrees away from it's proper orientation, thus can't move across all 6 clicks because the lever is hitting the pod.
Remove the lever and re-install at 90 degrees away.

"6 clicks" would mean they are 7-speed. The final position is with the lever pushed all the way forward. The shim did nothing to change the number of clicks, it simply increased the amount of cable the shifter pulled for each click. I would check with the shifter bolted in place and all parts tightened down (see below).

What do you mean "the shifter won't go into friction mode"? There is a wire bale that switches the shifter between "SIS" and "FRIC". Twisting it all the way either way should activate the index or friction modes. I don't think this works well without the shifter bolted in place and the center screw tight.

Also, make sure the indexing washer is in the correct orientation. The wide tab needs to point down when everything is in place. Shimano calls is the "lever boss cover", part #2 in the PDF linked below.

Some advice: make sure that center screw is tight. If it loosens up, the SIS/friction switch can move to somewhere between the settings. This can damage the mechanism quickly.

Shimano PDF for 9-speed bar-ends: https://techdocs.shimano.com/media/te...9830628723.pdf
They are identical to all the other bar-end shifters up until the later 10-speed shifters, which have no friction option.

I would like to piggy back a related question onto this thread if I can.

I have a set of Shimano SLBS77 Bar end shifters. The RD shifter is definitely able to go from friction to indexed. The FD shifter does not have the SIS selection ring on it and is friction only.

Am I missing a part or is this the set up for this particular set (indexed on rear only)? I looked at the PDF linked to above and can't really see the selector ring on the front shifter.

Is there a Shimano Bar End shifter set with indexed levers for both sides?

Shimano's bar-end shifters are always friction on the left side.

They did make Tourney-level, Dual-SIS thumb shifters though.

Perhaps the wire clip fell off, if so there would be two holes for the ends of the wire.

And I believe there's a pair of wrench flats that can be used to rotate the chromed selector plate.

Aren't the holes actually drilled into the wrench flats?

This answers my question thanks.

This is NOS in the box. The left shifter just doesn't have the wire loop index/friction selector on it at all, I now don't think anything is missing.

Agreed, nothing's missing.

I didn't even realize that it was the left shifter that you were trying to change between index and friction, lol and there of course is no wire ring on the left shifter, nor any provision for it.
I guess I also lost track of the fact that you're not the OP.
