Service and refill in Europe? ABS seems to total market dominant here and I haven't seen any shops that provides this for BCA yet.
The air canister uses the same fitting as any scuba tank or paintball air canister, so can be filled at most any scuba supply or paintball supply store, worldwide.
Hmmmm... I've heard they need a special nozzle or something for this cylinder, so I don't know about the universal fills at scuba/paintball/fire stations. I'd check into it.
