I have Ultegra STI's. My problem is that that little cap on top of the shifter rattles on rough roads . I've heard this complaint all over the internet from owners of Ultegra. A long time ago, I found a website that had a very detailed way to fix the problem (with pictures!), but I never got around to actually fixing them so I deleted the website from my favorites. Now, the rattles have gotten too much to listen to, so I was wondering if anyone had any suggestions? Thanks!
