Mounted between the stem and the handlebar with velcro, I use my Alpkit Stem Cell to carry water. I get a
750 1182 ml container in easily (new model) and a 1.5l bottle of water fits easily in both the old and new models. Mounted here, I can actually drink water and as I can see it, I remember to drink. Carrying a bladder on my back is no longer necessary as I can carry two stem cells.
My bike, like me has a small frame and there is only one bottle mount. The stem cell is sturdy with a small exterior mesh pocket where I stuff sweet papers. I also keep my buff there. This could be made from a more flexible net style fabric as it’s more decorative than useful at the moment. Alpkit advertise the improvement as follows:
a versatile webbing ladder is bar tacked around the Stem Cell to provide multiple attachment points.’
Where to get Alpkit Stem Cells
Buy directly from Alpkit online. You can read the technical data there too. They cost £18 each and are as useful on a day ride as they are on a multi day bikepacking adventure.
Update: February 2015
The newer models are a little bit wider and have a band of webbing that allows for the adjustable positioning of the velcro. (velcro is pre attached on the older model). This makes for a better fit around the handlebar and stem. They also have super duper double sided velcro which is much neater and less bulky than the original model’s. That additional gain on the diameter means that a stainless steel Klean Kanteen with a capacity of 1.2 litres fits snugly. Kind of like a marriage made in heaven.
