Bar End Shifter Play

Hi all,

I'm getting some bad shifts on my bike and I'm fairly certain it's because of some play I have between the clicks on the bar end shifter. I can move the shifter up or down between gears and the shifter will stay wherever I leave it when (per my experience) it should naturally pull the shift lever down to the click before the next higher gear.

Bike Info: 2012 Jamis Aurora (9-speed rear derailleur, Indexed MicroShift bar end shifter)
Use: Primary transportation vehicle. 8-mile daily commute, errands, short tours. Stop, slow, and go fast traffic. Frequent small hills (lots of shifting).
Total mileage: 2500-3000 miles since last November
Replaced Parts
  • Rear Derailleur - From 9-speed Tiagra to 9-Speed Deore (Tiagra damaged, no longer made)
  • Cassette - SRAM... forget the model. Low cog had +2 teeth from stock.
  • Chain - SRAM... forget the model. Same as stock.
I'm assuming it could be one of the following problems, but would like some advice before I dig in:
  1. Worn Cable Housing or Housing Needing Lube -- This is not my first suspect since the rear shifter and brake cable and housings were replaced just 4 months ago.
  2. Worn Bar End Shifter -- Can this be "spruced up"? This is my first bike with bar-end shifters.
  3. Something else?

So what do you think? Where do I start?

please explain what you mean by
bad shifts

in my experience
shimano lever style shifters such as bar end shifters

edit
just noticed that you dont have shimano shifters
this bit of advice does not apply
/edit

work without problems for decades
so i would be surprised if the shifters were damaged

although
maybe the SIS/friction selector
is not all the way set to SIS
and this is causing some slop

or maybe the shifters were disassembled
and put back together wrong
as this will lead to odd behaviour

aside from that
i cant think of anything
but it would help if you
please
explain what you mean by
bad shifts

Microshift barends have a center tension bolt that may have worked loose or gotten tighter. Try adjusting it to see if that helps. Also, you mentioned the OEM rear derailleur was damaged. Was the bike in an accident? If so the derailleur hanger may have been bent and this could easily cause shifting problems.

What I mean by bad shifts: Let's imagine the following represents the amount of movement in the bar end shifter. Each "o" is a small distance and each number in parenthesis is a fully when the index clicks.

o(1)ooo (2) ooo (3) o oo(4)ooo (5) ooo (6) ooo(7) ooo(8)ooo(9)

There is a little bit of "play" or ability to move the shifter above/beyond the first gear index click. No biggie.

My concern is that when I press pass the (3) click, the shifter doesn't spring onto the (4) index click. It will happily sit in some space (between (o). As a result, I need to gingerly push the shift lever onto (4) index click until I feel the resistance and then begin pedaling again.

If I had a friction shifter instead (this model is index only), I wouldn't care because I wouldn't be relying on the indexing. But I am here.

Thanks for trying to help out, btw.

Your Microshift bar end shifters may not be 100% compatible with "Shadow"-style Deore rear derailleurs.

The bike was in a collision (wrong way cyclist ). The hanger was bent in the collision but was repaired and the new derailleur was installed.

I played with the tension bolt and it seems that there's still some play in the space between the clicks when I loosened the bolt. This is leading me to believe that the housing is already worn somehow. That would be the only place of additional friction in the system that could reducing apparent spring tension thereby preventing the shifter from properly sit on a gear click instead of in between.

Other than presuming it was it was damaged , go buy a new one . its past the blind-guessing in text, point ,

so when off work* ..., go to a shop and show them your issue, .. I doubt microshift economics extend to internal small parts,
which goes back to the first supposition , you buy a new lever.

* most seem to write from the company computer during day.
