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 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 >>
I know some bikes come from retails like Walmart, and some others from quality shops. But my question is how do you tell one bike is from retail? And how do you tell if the other is from a bike shop? I also read a few months ago these two different buying choices have slight differences in its quality. Is that true?... Read more >>
I have a squeak that seems to occur on every third rotation only when I'm applying real pressure such as climbing or accelerating hard. Seems to be from the rear but hard to tell. Had the bike (2014 Tarmac w/ultegra)serviced and it was quiet for about 100 miles and now the squeak has returned. Any ideas? Thanks!... Read more >>
Under power I don't hear or feel anything unusual
But if I rotate the crank backwards I feel roughness and more noise than I believe is normal
I ride frequently with a headset on and haven't noticed this noise until a recent ride without the headset on
Back peddling isn't something I'm conscience of doing either until I first noticed that something is amiss
Can someone tell me what's failing?
Ive taken the rear wheel of and spun in both direction but can not detect anything unusual but maybe it needs weight on the wheel?

As soon as it hits around 10 or below my bike will "skip" when I pedal. I have an all city nature boy. I got it last spring. I have put a good 1000 miles at lease on it since may.
It pedals fine until I coase for even just a second. Then when I pedal, it just spins and spins. I have to stop completely and it will catch again. It is a single speed so there is no other gear to "jump" to. It is a pain in the butt when I ride 6+ miles a day. When its 20 degrees out it will not do it. Only when its very cold. With the coldest part of the season upon me, I need to figure this out.

I was wondering if you wanted to help me with a project that may be more than I can chew; I bought a specialized stumpjumper recently at auction blindly - that's to say I didn't take a look at the mofo before I bid. Suffice it to say I won it for around £125 and now I have it.
It's condition is..interesting. Interesting in the same way that an ancient temple is interesting - fascinating to look at but it's seen better days.
Over the next couple of months I want to get it looking spic and span but here's the thing... I don't know a spoke f... Read more >>

I have a couple weeks pause before I can get back to the Peugeot re-build....
I've been debating asking this in open forum, because I don't have any background in this sort of thing...... and it seems this subject can become a potential Hot Topic I've seen on multiple threads..
My Question is about the use of Loose Ceramic Ball Bearings....... In an old Peugeot Road Bike, in Axles, Crank, and Pedals.
Not: "Will I feel anything?"
Not: "Are they better?"
Not: "Is the expense worth it?"
But: "If they are Given to me FREE, are Ce... Read more >>
My 2006 Trek 4300 went swimming during hurricane Sandy and many of the components have seized up. The frame is in good shape, but everything else is shot, so I would like to pretty much tear it down an replace every component. I have no doubt that a complete overhaul will easily cost double the bike's value and I have no problem with that. My issue is: I cannot find info regarding what replacement components will fit the bike nor can I find a service manual. Any assistance will be most appreciated.

Newbie here to the forum, but I've diddled around with bicycles since clothes-pinning a playing card to flap the spokes, and that was a long time ago. I'm not specifically a bike nerd or wrencher, except, perhaps, when I need to be. I have tons of experience working with all sorts of materials, machines, and processes, plenty of which translate to things bikes need done to them, so can contribute things to this community from that vantage point...

Very new to biking.
I have an older work horse road bike and a new to me mountain bike - CCM Nitro XT.
The rear tire on the CCM doesnt seem to be spinning very well. Doesnt coast well, esp. down hill.
I turned both bikes over and spun the back tires with about the same amount of force and the road bike spun for over a minute and the CCM spun for 7 seconds and came to a complete stop.
Any ideas where I should start? Is it possible something is just too tight?

I was recently given a haro backtrail x2 and a lot of the parts are old and rusted so i want to change most of the parts. Its going to be a gift for my little brothers birthday so i only have a couple weeks to get it done(beginning of sept.) Unfortunately im not 100% sure of what im doing. As far as taking things apart and putting them together i think i can figure that out but im having a hard time figuring out what parts to buy. I THINK i know what i need but i dont want to order parts and find out im wrong. He rides in the woods for the most part, jumps some stairs and likes to ride fast so... Read more >>
