Arundel Synth Gecko. 100% silicone. Stretchy, durable, can be washed and reused indefinitely with reasonable care. Doesn't take a set or permanent curl, so it can be rewrapped without regard to how it was wrapped before. No adhesive, the soft, gummy wrap adheres to itself. Really grippy and soaks up road vibration.
Not cheap at $35 but a good value considering I've rewrapped it several times this year. Even $10 Eclypse or similar cheap foam wrap would have cost more by now (and it's not good tape).
And I'm about to rewrap it again, over a second wrap of cheap bar tape (I'll probably recycle the cheap Eclypse wrap since it won't show).
