A few months ago I bought a SunRace R90 9 speed bar end shifter off eBay because it was ridiculously cheap and left it in a drawer.

My 8 speed Ultegra bar end has just died and I'm considering buying a 9 speed cassette and chain and using my eBay shifter rather than forking out £40 for a new lever.

The only question is if the SunRace is in working condition.

Perhaps naively I'd expect to be able to move it through 8 'clicks'. In actual fact I can move it through about 15.

Is this normal, or has it got a fault?

Without forking out for parts I've no way to try it out.

    Is it possible you got the left hand friction shifter? On the R90 sets (L&R) the 9sp RH shifter is indexed and the left is a friction shifter. You might be best off installing it and seeing how it functions, some shifters require tension from the cable to function correctly. It has the same ratio as shimano so you should be able to test it out, you just don't want to go to the 9th non existent gear, but should be able to shift a few ups and downs to feel it out. – Nate W Jul 22 '16 at 20:34
  • @NateWengert It's definitely a RHS one and definitely indexed. I believe the spacing between cogs is slightly different for 8 and 9 speed, but I guess there's no harm in trying it. – henry Jul 22 '16 at 21:32

Found this on Rivendale Bike works regarding the R90 barend 9sps:

Use: They click but don’t index. Out of the package and not on a bike, they click about 18 times. In the span of shifting over a 9-sp cassette, they click about 13 times. This sounds trick or confusing, but it isn’t at all. Like a with a pure friction shifter, you move the lever til the shift is made. With these levers, the first three clicks coincide with the small three cogs. After that, it takes two clicks to get the subsequent cogs. Now, I totally understand if this weirds you out, but don’t run away so fast—nobody on Planet Earth has shifted these levers even 1/20th as much as I have, and I’m telling you, it is a cinch. In the mid and upper range, one click isn’t enough, but two clicks are.
