Oversized Water Bottles


Reviewed by GB – March 16, 2014

I was looking for larger capacity water bottle for the upcoming gravel grinder events that I’ll be riding soon. For purposes of this review, I compared two options currently available with a large regular “gas station” bottle and my normal, everyday 24 ounce bottle. I ordered the SIS bottles from Europe and bought the newly designed Zefal Magnums locally from Pedal of Littleton.

While the Zefal Magnums have had a reputation for leaking; I could not get them to leak, even with super-hot water. The new design must be working. The SIS bottles do hold a couple more ounces due to a greater taper and are taller. Both bottles slide in and out of my Ti King Cages better than my regular 24 ounce bottle because they are tapered.

I’ve also found the Salsa Nickless Cage to be useful as I can easily adjust the size, allowing me to carry the larger bottles.  This cage can be mounted with standard bottle cage mount or it has pipe clamps mounts, so it can go on fork legs or frame tubes.


Bottle Stats:

The Zefal Magnum – 105g, carries 32oz, 260mm tall (10 1/4”), 73.7-77.4 diameter  

The SIS (science in sport)98g, carries 34oz, 277mm tall (10 7/8”), 74.6-81.8 diameter

The gas station bottle  – 53g, carries 50oz,  295mm tall (11 /58”), 89.8mm diameter

My “everyday” bottle – 96g, carries 24oz, 240mm tall (9 7/16”), 74mm diameter
