Zefal Bag Z-Box

This is a well built container that has a nice, wide opening in it for getting things in and out. I was actually surprised by how bit it was. Roughly the height of a 24 oz water bottle (including the valve). Since the cap of most water bottles are an inch or so lower than the top of the valve, I guess I wasn't quite prepared for how big this container really was.I ride a medium Salsa Cutthroat which has 2 water bottle holders on the inside of the down tube and 1 water bottle holder on the inside of the seat tube. This bottle will fit in either the lower down but holder or the seat tube holder but it is a very close fit.I use the bigger compartment to carry a spare inner tube for my bike (the tubes for a 2.2" tire are pretty big).

Very usefull. Holds a lot. Would have given 5 Stars if it fit the bottle cage a bit better. The notch to catch the lip on a standard bottle cage is a bit off, but it still catches. (Fine on a road bike but might not work well for MTB)

Basically, it's a hard plastic cylinder with a screw-on cap, so it's waterproof. Sweet. I bought the large size, which has a screw-in extender that goes in between the cap and the main body. This extender has a partition that screws in just above the threads that attach it to the main body. So, depending on preference, you can have an extra separate compartment, or just extend the main body storage space. It's simple, but clever.That said, I didn't end up needing the extender. Without it, the tube fits my spare 700c 32 tube, multitool and tube repair kit/tire removal tools with ease. Keys would also fit, maybe a small flip phone (the tube's diameter is just too small to fit my Galaxy S6), but not much more. For me, the size is pretty much perfect.It fits snugly into my water bottle cage, secure enough for road riding, but more aggressive off-road folks will probably want some velcro straps or the like to ensure it doesn't bounce free.EDIT: I've since eliminated my bike pump mount, and using the extender on the z-box (with the "floor" removed), it now holds all of the above, plus the bike pump! I love this thing!

Excelente para guardar capa para lluvia o herramientas para bicicleta!

I bought this and the one by Elite for carrying spare tubes, tire irons, patch kit and CO2 cartridges + nozzle. What I like about the Zefal product is you can select one of two sizes. There is a removable top section that allows you to use a regular waterbottle size. The removable 'stage' also has a floor that screws in and is removable so you can have (1) just the smaller size bottle or (2) larger bottle, all one space, or (3) larger bottle with regular waterbottle size below and small compartment comprising the extra stage on top. The plastic is also thicker than the Elite giving it a sturdier overall feel. Should hold up in wet conditions well too.

Product is a little smaller than I expected but seems like it will work for my needs. I hope. Now the delivery and wait time was ridiculous, don't know who to blame. This small package was received in Philly USPS distribution center on March 28th and sat there 10 days and I just received it today April 8th. Its literally 3hrs drive from me in Philly. INEXCUSABLE!!!!!!!!!

Awesome storage option for an extra bottle cage. I was a little hesitant purchasing this one because I knew there was a divider between the top and bottom portions on the large size, that could restrict the lenght of items it can hold. However, the divider can be removed and stows away in the cap. I'm surprised they don't mention this in the description. Overall great design and good quality!

I really like this case. It is cleverly designed and versatile. The main compartment is the size of a standard water bottle. The additional screw-on top section is great for storing smaller items. I have a multi-tool, an expensive, hi-lumens light that I don't want mounted all the time, two tire tools, my iPhone mount (when not in use) in the bottom compartment. The only fault - which is kind of a major one - is that the screw threads that the top section screws onto the bottom section are not deep enough - only about two rotations. They are so shallow that the top compartment can be pulled right off with a relatively light horizontal motion. The horizontal motion is not one that is likely to occur in normal use, so I have kept the case, but seems like the manufacturer should have caught this and corrected the problem.UPDATE: Reduced to one star because, unsurprisingly, the top fell off on my commute home today, After noticing it a mile or so down the road, I turned back to try and find it - to no avail. Lost not only the top, but also a multi-tool and or small items kept there. I got well over a year of regular commutes, but the design flaw of not having enough screw rotations to keep to top on to be so obvious that I find it inexcusable.

Es un bote de plástico con bastante espacio para guardar cosas, la calidad es buena sin ser excelente tiene una parte chica para cosas pequeñas, y la parte de abajo para herramientas o lo que se necesite guardar, en la etiqueta dice que es resistente al agua, no la he probado en lluvia, tiene las mismas dimensiones de una botella de agua para bicicleta pues asi esta diseñada, de resistencia aun no lo se.
