I recently dug thru my huge box of bike components I have in the garage and found an old a bag with a snap clip on it. I added a block of wood and walah I have storage for a tube, bike multi tool, tube repIr kit wallat and keys. I will post pictures soon. Have been riding some just added 700c 25 c continent black chili tires WOW awesome ride no loss in roll. The bike shop told me the 25c tires are actually fasted than 23 c tyres and are safer.
