3M Scotch Rubber Mastic Tape 2228, 2 in x 10 ft, Black, 1 Roll

This is one of the best products I've found for protecting chainstsys and problem chain slap areas. Lasts, moldable. Definitely use again.

This stuff is expensive but pretty much everything from 3M is as well. It works great for bike frame protection and holds up to cleaning and riding. It is stretchy and adheres to odd curves and surfaces. There really isn't anything that I have found that is like it.

Great for sealing and plugging holes. Also good for waterproofing non-outdoor crimp connectors, at least as a temporary measure, if you run out of the outdoor style and have to make do.

Doesn't seem to be as adhesive as in the past or as stretchy. I also remember it being adhesive on both sides, and this one was not.

I love this tape and use it on my bike for chain slap. It is very sticky so I recommend putting on carefully as it is likely to stay for a while. Good stuff.

This stuff is awesome, I use it for my carbon frame protection, used it on chainstay, downtube, seatpost, did not come out yet. Much cheaper than anything I could have bought made for bikes.

Amazing how versatile this thing is, using it as chain protection and also as a cover for my bicycle rear link to avoid mud, rocks and sticks from getting into link area. Tape flexibility is great and haven't had any issues if it starts to peel just replace. Great purchase and will be buying more for sure.

Fantastic product thousands of users. You get what you pay for it is very expensive but certainly the best tape I have ever used.

Das Band ist relativ dick und läßt sich sehr gut auf Oberflächen modellieren. Die Klebekraft ist sehr gut. Ich benutze es um an meinem Mountainbike durch Steinschlag gefährdete Stellen, ebenso wie die Strebe unter der Kette abzusichern. Das Band erscheint relativ teuer, ist aber jeden Cent wert. Ich kann es für den beschriebenen Zweck vollumfänglich empfehlen.

Compré esta cinta de goma para proteger el cuadro de mi bicicleta donde la cadena lo golpea. La cinta es de goma gruesa, pero se aplica fácilmente a superficies irregulares como esta. No es barato, pero los protectores de cadena también pueden ser caros. Usando esto, puedo hacer tamaños personalizados y proteger otras áreas de mi bicicleta.

Great product. A bit expensive but there’s plenty supplied. Easy to shape/cut and sticks down well.

Excellent product for waterproofing

This seems to do the job nicely. I've used it as a frame protector on my mountain bike at the chain stay. Goes on easily and sticks very well. I can't see it coming off.
