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.
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.
These levers fit my 22.2 mm bullhorn bar perfectly. The cable pull is in line, minimizing friction. The cable exits close to the bar, allowing you to wrap the cable housing under your bar tape; This leaves the bar uncluttered and you have full use of the bar tops and the forward position. They work just fine with the cantilever brakes on my bike.
I bought these for a new Postino type handlebar to accommodate a front kid seat on my old drop handlebar ten-speed. The installation was easy. They look attractive and work well. Since these plug into the ends, the bar tubing is clear and smooth. I used cotton tape and installation was easy.
