Velo Orange Belleville Handlebar
*discontinued product no longer in production* last remaining stock
The Belleville is 43cm wide (or 45cm outside-to outside) and has zero rise. That's fairly narrow for a city bar, which is an advantage in traffic. Reach is about 18cm; the straight grip section is a generous 150mm.
25.4mm clamp area. Aluminum alloy.
These bars are available in two tubing diameters, 23.8mm road-sized and 22.2mm mountain bike-sized (clamp area is 25.4mm on both):
22.2mm (MTB-size) bars accept MTB brake levers and clamp-on shifters. They do not work with bar-end shifters. The only inverse levers that work are Dia Compe levers in the 22.2mm size.
23.8mm (road-size) bars accept standard inverse brake levers, standard inverse shifters, and 23.8mm city brake levers. In short, anything made for road bars fits. They do not accept MTB levers or shifters.
