Maintenance/Tire Issue - Giant Expressway 1

Hey there everyone,

I recently acquired a Giant Expressway 1 from Craig's List - I love the bike and all, but I just blew a tire yesterday. Bummer, huh? Except I took a look at the bike today and it was actually fine!

Yesterday when I was riding, I ran over a small branch, an acorn, or something, and heard a very distinct, loud "pop!" sound. Assuming the worst, I figured I would be experiencing a flat in seconds/minutes, so I decided to ride as far as I could before I started to feel the tire give way - yes, a bad idea, but I really did not want to walk home in the dark. Stupid me for being out so late I guess.

Anyway, I never did feel the tire deflate at all - it only got harder to pedal. When I reached home, I inspected the bike - nothing in the derailleur, no scraping of brake pads, no flat tire. I figured it was most likely a slow leak, but today I rode it, and for the most part, it was fine. It was only a little hard to ride (think high gear pedaling, but no speed/distance achieved, like going through quicksand). But it was actually somewhat easier than yesterday.

I'm starting to think it was all just in my head and the bike is fine. Maybe I just had a particularly invigorating ride, and when I got back to "normal" speeds, I mistakenly thought my bike was busted. The other possibility is that maybe my bike is equipped with a slime tire, which explains the lack of lost air.

Has anything like this happened to anyone? I'm probably going to ride it tomorrow, (because I'm just addicted to my new bike, haha), but I'm thinking I should bring it to a repair shop over the weekend.

Take some photos of the suspected area and maybe we will see something. Congrats on the new folder.

Sounds like something is dragging, perhaps the wheel is misaligned? Brakes dragging? Perhaps part of the stick is caught in the drive train, fender or frame?

Is it possible the POP was from the acorn/stick/whatever breaking & a bit of it got stuck in your wheel? that has happened to me before (both the loud POP & trail debris getting wedged in & slowing me down....)

Thanks guys - yeah, I did a quick check on my bike and didn't notice anything caught... maybe I missed something though. I'm at work right now, and I rode the bike here, and it was fine for the most part - maybe whatever was getting stuck has already been minced enough for it not to matter.


I'll take pics and inspect later when I get home though.

Hey everyone! Wow, yeah, I didn't get to take pictures that day, and when I did take them the next day, I never got around to posting here - whoops! But here are the pictures now.




As you can see, everything looks pretty much in order - no derailleur gunk or anything.
I checked the tires, but didn't notice any holes... they're double walled though, so it's possible that that may be contributing to the covering up of a hidden leak.
The fenders were actually a little misaligned, but a spin of each tire above ground level confirmed that nothing was touching.

I'm a little at a loss for words, but it's riding pretty well now, so I can deal.

Also, it's Sunday night, and I never did get to take the bike to the shop - went out yesterday and had to take care of more pressing things today. Oh well, I'm sure I'll have some spare next weekend, and if not, some time soon!
