How about these?
Dia-Compe Inverse Brake Levers, 22.2
These are the first inverse levers we've seen that fit MTB, 22.2mm, sized bars.
The bodies are made from reinforced plastic, but they look like gum rubber. The levers are aluminum and the cables run under the bar, so there is no need to drill. They are very easy to install and set up and look great with our leather city grips.
These levers are made for mountain bike-sized bars (22.2mm outside diameter) bars with an internal diameter of at least 16.5mm. These levers work with caliper or cantilever brakes, but not V-brakes. About 160g.
Sold as a pair.
