Like gaucho777, TA cages. The alloys are light but a bit bendy with full bottles and tend to leave grey marks on the bottle. The same, original style, in chromed steel is slightly heavier, grips bottles like a pitbull and is so strong I have lifted my bike up with it (not recommended typically). Never had one of the plastic clips break although a very high mileage one cracked. Great cages. Remember, steel is not just for C&V framesets!
