Review on Topeak TC2260B Wedge Strap Mount by Jeff Jordan

In the small version, to my surprise, I was able to fit two 25mm hoses, four 16g CO2 cartridges, two tire levers and a CO2 blower (attached to the top of the cartridge). Well if the inflator was a canister type I doubt it would fit. I would have to take out some items to install the canister. Next year I will be changing the tires on my road bike to 32mm. I think two 32mm tires will fit, but it gets very tight. The bag is of excellent quality so I expect minimal expansion over the next year. There are only 3 cartridges in the photo I took, but I took one out so everyone can get a better picture of the inside of the bag. But I can definitely fit four 16g cartridges in one bag. Hope that helps!
