Over the past two years I have used black gel cork tape from:
- Bontrager
- Cinelli
- Forte

As far as I can tell, all three are EXACTLY THE SAME TAPE.

The only difference is:
- Bontrager has the "B" logo stamped on it, and reflective plugs.
- Cinelli has the "C" logo stamped on it, and black plugs.
- Forte has no logo, and chrome plugs.

Personally, I prefer the clean, unstamped look of the Forte.
