I have those Cane Creek brake levers on three bikes, on a couple other bikes I have the older shaped Tektro that was nearly identical to the Cane Creek levers.

Newer Tectro brake levers changed the shape of the lever, I only have the older ones.

The only difference I saw between the Cane Creek and the older Tektros is the rubber hoods on the Cane Creeks have lots of tiny little lizards in the pattern.

In this photo I have a Campy brifter on the right side of the bike (left in photo), the older style Tektro lever on the other side. The older style Tektros and the Cane Creek levers are so close to the same shape and look of the Campy brifter that in a quick glance you don't realize that they are different manufacturers.
