Shimano STI shifter attachment problem(8 posts)

Shimano STI shifter attachment problemCaptaffy

I recently got a new bike (khs cx100) from my LBS.
Unfortunately, this weekend I had a bit of an unlucky streak. First I dropped my bike while adjusting one of my pedals, causing it to land on the right shifter. As a result, the shifter is now pointing at a rather decent angle inwards.
Then an errant elevator door slammed in to my other shifter causing it to face inwards as well (albeit not at such a large angle as the other one).

This seems to me to indicate that they were not attached adequately in the first place.
On my old bike (which had the exact same make of shifters), I'd dropped it and had spills, and they remained in the same position.

I'd take it back to my LBS and have them repair it, but they are closed for holidays (wtf??) until Sept. 6th.
I don't want to have to pay someone to fix this since I think it should be done for free by my LBS.

I don't know how to repair this though. I pulled back the rubber on the shifter and found a bolt that accepts an allan key. It looks like if I loosen this, I could adjust the angle of the shifter and then re-tighten it. But I can't pull the rubber back far enough to actually fit an allan key in there.

I'm probably in over my head, but I'm steamed about having to pay for this (however miniscule the amount).

Does anyone have any experience with this that they could impart to me?
Yes, this is the right bolt.PeterRider

You just have to tighten it more. You don't need to pull the rubber completely back, just enough to get an allen key in.

You don't want to tighten it too tight however. In a fall it's better that the whole unit gets twisted rather than having parts break off because it can't twist. In an impact, something will have to give. Think of it as a crumple zone with the worst damage being a twisted shifter rather than a broken one.

Because of the way that the clamp is designed, I don't think you could break the shifter off instead of twisting it. Tighter is better, unless you have fragile handlebars, in which case, the clamp could crimp the bar.

Thank you.
I will bear all of this in mind when I do it.

I could not manage to actually fit an allan key in the space when I tried on the weekend however. If the part of the key after the right angle (the part that fits in to the bolt) was half as long, I'm sure I could have done it.
Do they manufacture allan keys where this part is shorter?
Perhaps I just didn't move the rubber up enough.

Oh well. Try try again.

You should be able to stick the long end in. It's a 5mm wrench, you don't even really need to slide back the rubber- just slip the wrench in and feel around for the bolt, tighten, and you're all set.

It sounds to me like you're trying to get to the screw from the wrong side of the hood. You should not need to fold the hood back at all. There is a channel under the hood on the outside of the lever (about 15mm above the pivot) You can insert the long end of the key in from the FRONT of the hood (under it) to reach the screw.

You were spot on. :)
That's exactly what I was doing.
When I got home today, I tried just pulling it back from the front, and voila!

Thanks everyone! Your help has been invaluable.
