Zefal Bottle cage Fiberglass, red

After much research of Amazon offers for bottle holders and their reviews I decided for the Zefal fiberglass holder, because this, in my view and my needs the best price / performance / usage ratio has and the ratings of other buyers have confirmed this ,

First I only ordered a holder for the sample that has convinced me quickly. A second holder I have now ordered.

Assembly:
Installation is quick and easy to perform with a hex wrench. However, the screws can screw it better and faster if you put the long end of the wrench into the screw head.

Since the holder has no fixed holes for mounting, but a kind of mounting slot (see photo) it is flexible screwed. Namely, since obviously in wheels have not all holders holes in the seat tube and down tube the same spacing for the screws, it may be that support can not be screw. Through the two slots of the holder, it is possible, depending on the distance from each other to lock the screws to fit or to make the distance from the top tube is shorter or longer (thus suitable even for smaller frame sizes quite 1.5 liter bottles in the holder without the top tube to initiate).

Use of bottle sizes:
The fiberglass construction of the two front support arms act as a kind of flexible or expandable cage. The two holding arms are not interconnected and so depending on the bottle format and size stretchable without breaking. Despite this flexible design, the bottles are firmly in the holder and keep shocks by bumps and unevenness without slipping or falling out. When Trying to both plastic and glass bottles have currently loaded. In plastic bottles all sizes from 0.5 liters were - 1.5 l inserted.

Another advantage of the expandable retaining arms is that you can use the on-board bottle while drinking also without stopping while driving. Many other structures or aluminum holder are partially so rigid that you have difficulty getting the bottle into the holder or remove again. With practice, you can contrast with the Zefal Holder pull the bottle just up and return with a slight click or gentle tug from above back in its holder, because to adapt the holding arms of even the bottle.
