Elite Patao Bottle Cage, 74mm diameter.

The standard Patao cage from Elite is available in black or silver to match any frame and suit most tastes, and the sleek Italian design and good looks make it fit to grace any bike.
This 74mm diameter version allows the use of standard size water bottles, so is more versatile than the slimline 66mm alternative.
It is built from a robust magnesium alloy, giving a fairly light weight without being too expensive.
