8 speed sti problem(3 posts)

8 speed sti problemmcbaker55

I'm having a problem with my 105 8 speed STI shifters. When it drops below 40 degrees or so, the inner levers fail to shift reliably. The throw gets really long and it feels like the lever is not "catching" to perform the shift. This happens to both shifters, but it is worse on the right one. When it's warm out, it's fine. I also had an RX100 8 speed STI do the same thing. Is there a fix (or is the fix to buy a new one?)?

I assume that the cog spacing between 8 speed and 9 speed is different, so a 9 speed shifter would be incompatible with my 8 speed setup.


check that the grease -replace the cables......the bull

Maybe you can thin it out by spraying some tri-flow in the lever.
Is there grease on the cables?they work better dry!
Try replacing the cables-housing and run them dry(no lube).

I am having the same problem with my left 105 8 speed STI shifter. So far it has only happened in the cold weather. I installed a new inner wire and cable housing (with no grease) and this has not solved the problem. Is there any way to open the STI shifters up so that I can clean and relube them without having a hundred pieces fall out of it that I can't reassemble?
