My gear lever felt a little wobbly on my last ride. When I got home I had a look, but I think I might be missing a bolt somehow? I can't quite figure out which I-Spec version I have to find the correct bolt. Any ideas?


If its SL-M8100 I-Spec EV you appear to be missing
Y0FA44000 Unit Fixing Bolt
That bolt rattled out of my deore ispec EV shifter. I used a rotor bolt to fix it. Maybe a tad long as when tight there is still a little play. May look for a washer.
Shifters shouldn’t fall apart in normal use shimano!
Put some loctite on it when you replace it, they usually come from the factory with some on, that little blue splodge. It serves two purposes if you use the threadlock, non permanent variant, it stops nuts and bolts vibrating loose and it also prevents them corroding and seizing together.
I've also still got a rotor bolt with a washer on mine.
Thanks everyone, fixed with a rotor bolt and washer 🙂
