Q: What is the diameter of this pump? I'm hoping to store it inside 31.6mm seatpost

Dear Rhauff Thanks for reaching out to us with your question. I have measured the diameter of the pumps for you: GM04LT - 26mm and the GM043LT - 32.8mm this includes the protrusion of the valve. The GM04LT is for higher pressure Road Bike tires and the GM043 is for high volume low pressure Mountain Bike Tires. Please remember that the seat post size is the external diameter so you probably should check the internal diameter is big enough as that can vary and will depend on the material used. I hope that this was helpful for you and please let us know if there are any other questions that you have about the pump. Many Thanks.
