3 freebie CO2 cannisters with your order at Cell Bikes.
Dont know if any of you use the Cell Bikes online shop but if you do and your buying in the next week or so and have one of the CO2 inflators chuck this into your order.
Cell sometimes have some pretty cheap clearance stuff but their delivery costs can be a bit high. I've used these cannisters on dirt bikes. They're magic for when you need to pop the bead after a flat (assuming you dont have a really good high vol / low vol pump which do the same thing with just a little more effort)
