Last year I bought an insulated thermos that would fit in a bicycle water bottle cage. This thermos (which is not longer in production) kept my drinks warm on long rides even when the temperature dropped to well below zero (Fahrenheit). Unfortunately, the geometry of the bike frame I wanted to use it on was rather tight—since the thermos was so long it was impossible to put it in the bottle cage. The folks at the local bike shop suggested I try the Zefal WIIZ Side Mount Bicycle Water Bottle Cage and I am happy to report it works great!
Since most WSD (Women’s Specific Design) bikes have limited space on both the down tube and seat tube, the Zefal WIIZ is a great product for these bikes as well. And, unlike most side mount water bottle cages, the Zefal WIIZ is a can be mounted for either right or left access. The height of the cage can be adjusted quickly—this is handy if you have a short bottle and want to bring it up closer to your hands.
Owners of full suspension bikes will also appreciate this water bottle holder since it not only fits small frame bikes, but it holds bottles very securely on rough trails. The Zefal WIIZ is very lightweight (only 65g each), which should make every triathlete and Weight Weenie very happy.
The Zefal WIIZ Side Mount Bicycle Water Bottle Cage is made of thermoplastic resin and is available in either black or white. The WIIZ retails for around $8.00 at your local bike shop—if for some strange reason they are not able to get this bottle for you it is also available at Amazon.com.
