The Porteur 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.
The quality and polishing are very nice. The transition from the grip to the curve on the originals was a bit abrupt; our version has a gentler transition. The curves on both versions are fuller and, to us, prettier than the somewhat similar Champs Elysées bars used on the old Herse bikes.
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.
