12. How to Check If Your Bearings Are Worn
Did you know that you can check the health of your bearings by listening to your bike seat?
Here's a handy tip that will help you access whether or not any of your bearings are worn out. You'll need to have the wheels suspended in the air somehow, using either a repair stand, hanging it from the roof, or by getting a friend to hold it up for you.
You can listen to your bike by pressing your ear up to the front of the seat. It will act as a speaker, amplifying the bike's internal noises.
Now spin each of your components and listen to the sound. You will hear noise, but it should sound smooth and even. If it sounds loud and/or uneven, it is likely dry or worn out, and your bearings will need either an overhaul or complete replacement.
When checking the bottom bracket bearings, it's helpful to shift the smallest sprocket and remove the chain to eliminate the noise generated by the chain and chainring.
To hear the rear wheel bearings better, remove the chain from the freewheel by removing and re-installing the wheel, so that you don't hear the ticking as it spins around.
Since the headset doesn't spin around as fast, it's more difficult to hear if it's worn. Any dryness or wear in the headset bearings will be very obvious, and you'll feel a notch in the rotation if they're pitted. Pitting usually occurs when the front wheel is pointing directly forward.
I am looking for some inspiration really which way to take this either to continue or scrap this in favour of a 29er.
I have a bike that I have cobbled together over a period of time it used to be a kona cindercone frame I upgraded the front forks to sid's thinking it would make it ride a lot nicer and it still crashes over everything like it a rigid.
I was offered a nice Cube Reaction GTC pro carbon frame so I got it and it still rides harshly, I done some research to find that sid's even when at the specific weight setting run hard so I now run ... Read more >>
I'm new here so please forgive the dumb questions I will eventually
ask. Is there anything definitive available on changing out complete
groupsets. I see some things but was hoping for something that
would include info on the tools needed to complete a project.

Hi everyone, I recently had someone vandalize my bike. Not sure if they were trying to steal it or not, but it did get damaged. I want to repair it myself, as I don't think it would be too complicated. Just wanted some help with the part names.
First, the part that keeps the handlebars on the bike is missing - any suggestions as to what that part is called and where I can find a suitable replacement?
Also, the cables to the gear shift was also damaged. The thumb shifter itself is in one piece, just the cables were damaged. I think the brake cables are also damaged. ... Read more >>
Hello everyone, i got a Specialized 27.5" Pitch Sport 2015 and i was looking to replace all the unsealed ball bearings on the bike with sealed bearings (cartridge type?) like on the wheels, bottom bracket, and head set. I'd like to get a quality bottom bracket, a quality head set, and quality sealed bearings for the wheels. The problem is, is that I don't know what to buy. I dont know if my head set is a threaded, tapered or whatever. Yes, im new to all this so im trying to learn, but thats why i know nothing, lol... I'd appreciate any help you guy's can give me. Thanks

I run my early college high school's bike share program, and I'm worried about this summer. Despite the Dallas heat, we might have to leave the bikes locked outdoors until school is back in session. The bikes are $100 Wal-Mart single speed bikes, and some are rusted in various places. What can I do to make sure the bikes can survive the summer?... Read more >>
We just got a bike from our uncle that he won at a storage locker auction. Its a Giant Revel. I believe its the original Revel. It has a front disc brake, but it was missing the caliper assemble. The rear brake a standard brake with pads. The rear derailer was broken along with the front derailer. They are the Shimano FD-TX51 and RD-TX55. The front shifters/brake handles are both Shimano, but are different and are in rough shape.
So, I need to replace the front and rear derailer, front brake caliper, and the shift/brake mechanism. Can anyone direct me in the proper direction for ... Read more >>
Have I got this right. Turning the high or low screws counter clock wise increases the amount of travel of the derailleur mechanism on both the front and back? and turning them clock wise decrease travel? Is this the easiest way to think about it?
One other thing I have noticed when replacing both brake and derailleur cables is the new thinner stainless steel cables run much smoother in the Jagwire then the thicker ones they sell do and are much easier to thread through grip shifters etc. as the cable ends seem to be treated so they do not unravel or fray. Well worth the extra ... Read more >>

Can someone please clarify that I am on the right track regarding my bike restore.
I have a second hand Orbea Carpe that I am in the process of restoring and I need some help to clarify which parts I need to purchase (Bike link below). The previous owner had experienced some troubles during a ride resulting in the rear derailleur and chain being destroyed / twisted. This also damaged the rear break cables. The rear cassette is 9 speed, however the destroyed rear derailleur is a 10 speed. I will also be putting the bike in for a general service to have the rea... Read more >>

Hello all. I am riding around on a 10-12 year old Schwinn Voyageur. In the past i have taken the bike to a shop whenever I need to tune it up and have any work done. Circumstances have changed and I can't really afford to pay anyone to work on things that I should be able to learn how to do.
I've ridden bikes all my life, but have never had to learn how to repair or maintain one. I don't own any tools other than a few basics like a hammer or a screwdriver.
From what I can tell, my bike is in desperate need of a new chain. Also a good number of the gear sprockets that... Read more >>

I have a Huffy Superia and it is kind of messed up right now with the parts on it currently. Is there any way I can get good parts on it and make it a better bike? I know there's some people that find this bike kind of rip off but I love mine, I just need to put good parts on it. Here is a listing of the parts that are on it right now: For the thumb shifters they are Power (same as derailleur which is a Power Index System) a Power model front derailleur or chain guard whatever you call it, and 26 inch wheels. I don't know if the piece over the front crank is called the chain guard or front mou... Read more >>
