Rubber for mounting things

Can I buy rubber strip in bulk for mounting various things to bikes? I know the DIY answer is inner tubes, but these are thin and tend to degrade quite quickly. I’ve got a few things where the rubber is missing….

I’ve used some thick heli-tape for areas where I’m attaching frame bags or have a bar-bag / cables potentially rubbing the headtube.  Or is this more for grip like mounting lights to the bar?

Would 2228 mastic tape do it for you?

I use it for under zipties on mudguards and for chainstay protection.

Or is this more for grip like mounting lights to the bar?

More for grip, and yes things like lights etc.

Seems to be alot of self adhesive neoprene strips on Amazon

I may have misunderstood the thread title, as you were.

Thanks, needed the puerile snigger this morning of all mornings.

Haha, that could go a couple of ways… so to speak.

You were not the only one.
