Sure, having fun is important, but so is efficiency. A mini air pump with a built-in CO2 inflator might be overkill for some riders. Plus, CO2 cartridges can be expensive and environmentally unfriendly. Why not consider a hand pump with a pressure gauge instead? It may not be as flashy, but it gets the job done and can save you money in the long run. :thinking: #cycling #bikegear
