today was a great ride during lunch. all was fine till i hear a hissing sound at the signal light. good thing it's nearby my work already.. so i can still ride back.
after getting into office.. checked and found 4 of these plugged deep into my front tire; which i have no clue what they are... see photo
now my front tire is flat after i removed all 4. never saw my tire went down that quick.
anyway.. instead of using my park patch to fill up 4 holes... these tubes has been in there for over 6 yrs. time to change it.
so where do you guys buy affordable and reliable tubes at? do they sell them in bulk?
please kindly let me know. thanks~
