Minoura AB100-4.5 / 5.5 Dura-Cage

Lightweight & durable Duralumin bottle cage.
A cage for normal poly water bottle for bikes.
Dura-Cage is made of lightweight and durable #2017 Duralumin which is adopted on aircrafts. It's much stronger than the normal #5056 light-alloy material, so it can have same durability with narrower diameter that means we can expect lighter weight for same durability.
