I noticed my hood covers (the rubber one) are slipping up -- I pull them down, align with hoods, some time later again (when riding of course) -- they are up. It is really annoying. Granted I put my hands on them, and with the force it is expected in sense of the physics, but I would like them to stay put as they did last year.

Is it a matter of time, I use those hoods and covers the 3rd year, or there is a way/trick to make them sit put and don't move? Hardcore gluing hoods and covers together is not a best option since this in turn blocks access to hood screws and makes replacing bar tape harder.

My brifters are Shimano Sora STI.

Two things I’ve found which help: First, align them properly. There are slots in the plastic of the brifters and little protrusions in the rubber which are supposed to slide into each other. Second: Degrease with some alcohol. Even better is liquid chalk (it’s magnesium carbonate suspended in alcohol, used for climbing and weight lifting) because the magnesium increases friction.

  • Ha, great tips, thank you! By pure accident I have some chalk which I used for testing as an addition between tire and inner tube. Sep 4, 2020 at 16:26

    @greenoldman Umm, I'd be real leery of putting chalk anywhere near brifters. Little sharp mineral crystals aren't going to be good for the shifting mechanism. Sep 4, 2020 at 17:10

    @AndrewHenle: Of course you should be very careful where you put it. You absolutely don’t want it on the (inner) cables or shifting mechanism.

I've also got Sora brifters, and the hoods do eventually wear out. I replaced the rubber parts after about 2 years, maybe 20 000km, and several gear cables. They're readily available as spares, but be sure to get the exact model
