The rubber chainstay protector on my Rail has come loose and needs refixing. Can anyone recommend a suitable adhesive for the job?
It seems to have been originally fixed using double sided tape. I have tried Gorilla double sided tape but this does not fix securely to the rubber guard itself.

Thoroughly clean both surfaces and use a contact adhesive. Worked for our Rails where the chainstay protectors lifted at the front couple of inches. Once glued use cable ties to hold in position for a few hours. I used reuseable/releasable cable ties.

As an alternative to contact adhesive, consider hot melt glue. The use of zip ties is not just a good tip to secure the protector whist the glue sets, but is also a second alternative (ie no glue).

Yet another alternative that I used when I took my mtb to the Alps was to cut an inner tube and wind it in a spiral along the chainstay. I used zip ties to secure each end. It looked neat and lasted for a week's bombing about and being abused on the chairlifts. Whether you cut the tube radially or split it lengthwise will depend upon how thick you want the end result to be. Inner tube rubber cuts remarkably easily with a pair of kitchen scissors.

Take one inner tube
Cut it so its a long strip, then cut it up the middle so you are left with a long flat strip of rubber. It might be an idea to cut it length ways so the strip is about 2" wide, as this makes it easier to wrap without getting wrinkles

While stretching it, wrap on and (at the crank end) so it overlaps- this holds that end in place.
Then wrap it around the stay so it half overlaps the last turn, but make sure you keep tension on it so the elastic effect holds it very tight to the stay
When you get the the mech end, finish it off with a zippy or two. If you've wrapped the crank end properly, you'll only need the zippies at the mech end so it wont interfere with the crank and can guard against chain suck damage.

I wrapped mine with self amalgamating tape. It's rubbery and available from Toolstation.

3m heavy duty double sided tape is very strong, but you need to thoroughly clean both surfaces with isopropanol alcohol to achieve the strongest bond.

On my old banger, the chainstay protector is glued on from factory with contact adhesive. The problem with that is over time, mud & water gets under it & overcomes the glue. I've cleaned & refixed it three times now & it still works loose so I've given up & cable tied it. In the end, that will marr the paint, so I probably need to think again. Look closely & you can see the chewed rubber where it came off & got caught in the chainring.

I'm a great lover of low modulas silicone, hold splashbacks to any surface we fix to
Can't see it not fixing a bit of rubber
Might try it myself once I repainted my frame
