Hello! Im wondering if a 16gr CO2 Cartridge fit on hollowtech II crankset. I know the axle have 24mm diameter but I dont know the inner diameter. The thickness co2 16gr I found is 22mm. Have anyone try this diy?

Do you have the Hollowtech II Cranks?

 

[nonameguy]

Yep. But I dont have a tool for dimensions. And I dont have the co2 for testing.

I just measured and can confirm that a 16gr co2 is 22mm, but I don’t know about the cranks. I would guess the wall thickness of the spindle is more than 1mm though.

I just tried to put one in a couple of different Shimano 24mm cranksets (GRX and SLX boost). Didn't fit.

I just bought a Silca frame pump for my gravel bike so I won't have to carry CO2 cartridges any more!
