Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

Help

So, I riding next to a trolley track. Glance back and my wheel gets stuck. I didn't fall. But when I start riding again there is resistance. Kinda like a flat but without sloppy handling. I keep on riding and it goes away. I go home and flip the bike and there some noise coming from the bb. I wondering if this is ok. If you could not tell from me getting caught in the tracks I am a beginner.
Thanks in advance.

Its hard to tell. Most BB problems are caused by direct force onto it (pedals)
If terrain that the wheels touch were to have a damaging effect, you would have
to have tremendous force pulling the chian backwards against the chainring.
Im sure something like that would have caused a fall.

Also: Never ride paralell to any kind of tracks. You were very lucky this time.

I think your wheel is rubbing the frame somewhere. Probably the chain stay right by the bottom bracket

+1

Check your back wheel to see if it has been misaligned. If its even the slightest bit crooked, youre gonna have weird chain problems and rubbing. I would venture to say its probably a simple fix...

Thanks for the help
I checked the trueness of the tires and the straightness of the chainline, and everything is fine. So, I am assuming everything is good. Also, the noise from the bb was probably the normal sound from new bearings .

Look down your seat tube. Notice the 4 tubes that run from your seat tube to the back wheel. Is your rear wheel pressing against any of those (or has it left a skid mark on them?)

Also, you can try looking at the nuts holding your wheel on and check if they appear like they recently distressed some paint by sliding forward/back, that'd be a sign your rear wheel moved as well.

Your BB shouldn't make new bearing noise if it didn't before your wheel got stuck.


And just for your own info: your wheels, rims specifically would be what gets trued. Your tires are just that, the rubber part. Not trying to be a jerk, we all gotta learn somewhere.

The rear nut may have moved. I will loosen them up and re tighten them.
I know the rims are whats true but I was looking at the tires to check.

Edit: I have done this and it sounds smoother overall. Thanks again everyone.
