They are 48cm wide; reach is 14cm. The grip area is about 13cm, and they have about 15mm of rise or drop. The clamp area is 25.4mm.

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 bar end shifters, and 23.8mm city brake levers. In short, anything made for road bars fits. They do not accept MTB levers or shifters.
