Where can one purchase the chrome looking, stick on, lower frame protector? The one that stops the chain from rubbing on the lower bar.

Like these?

They used to make (non-branded) them in the 80's and I had them on my bikes. The one on my PSV has been stuck on the frame since I pretty much bought the bike.

I think this type of protector mostly died out with steel frames, but could be coming back with.....steel frames again.

Exactly, pricey little suckers aren't they?

Yes, they are. I remember we had a bucket of plain ones at a shop I worked at in the late 80's. Foam tape backed and had peel-away thin blue plastic protecting the shiny side. I think we sold them for $6 each or something. I am getting old.

Not chrome, but Velo Orange has these: https://www.velo-orange.com/lechprsead.html on sale now for just $5.

What do you all think is best? Replace a chrome one with a different color or leave it off all together. This is on older bike that originally had a chrome one. I can not see paying $25.00 for a chrome one off e-bay.

They have plastic ones in clear or black

What color bar tape or brake lever hoods do you have? You could try matching those colors.

The ones I owned (and liked) were polished stainless steel, very thin and flexible, but didn't rust. Don't know who made them and haven't seen any in years.

There's one on one of my Falcons. Ticks me off; it captured moisture and caused the frame to rust underneath. Had to leave the silly thing on.

I made one out of clear contact "paper", actually plastic, that I bought at a crafts store. I'd bought one of the black protectors from Nashbar a long time ago and never mounted it, and when it came time to use it, it had become hard and the glue dried out. To make one, I rough cut two pieces of the contact paper and stuck one atop the other, then traced the shape of the old Nashbar protector onto them. Once cut and mounted onto my bike's stay, my homemade protector is practically invisible and has done its job excellently with no separation or pealing.

I just got metallic 'waterproofing tape' from the hardware store and cut a chainstay protector out of a piece. looks pretty good. $8 for the roll which will probably make me 100 more.

I've bought the carbon-looking ones, and they were not good. They didn't bend, or stick, and I threw them away.

Just a quick note to anyone that has had the glue or tape dry up or if you wanted to remove the chain stay guard from another bike frame and reuse it this is what I do. First remove the old glue or tape and use something to clean the surface ( I use Goo be Gone) then Pick up a small tube of 3M weather strip adhesive,it comes in yellow or black I prefer the black and put a very small bead ( you do not need a lot and it can be messy if you use to much and can be a pain to clean) on the protector and stick it in place and smooth it down.I like to go right down the middle and stop a 1/8" before each end when using it for a chain stay protector,works good on head badges too.

The ones I've had on a couple of Fujis were like a very thick aluminum foil with adhesive. Looks a lot like the aluminum duct sealing tape you'd use in HVAC applications. I wonder if one could adhere that to one of the black ones to get the "vintage" look back?

I'm sure there's someone here who can do it...

Man, can't I even speak hypothetically anymore?

Sorry, my hypothetical-to-literal phrasebooks is at the cleaners.
