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'm undertaking a pretty important project for my college course on the use of specialised terminology - and I've decided to base it on (the parts and repair of) my beloved bike!
I must find very authoritative and established written resources that'll provide good information on the terms used when discussing bikes and their repair.
What do you guys consider these to be? I'd be interested in books, magazines, journals, websites, you name it. As the resources have to be as reliable as possible, books and respected journals would be preferred o... Read more >>
So I just bought this 820 off craigslist. It was in pretty bad shape and still is aside from a new, complete, rear rim.
So I noticed the crank is loose and could probably use some bearings. As for the drivetrain itself, it seems ok, but I don't know. Chain folds on itself when coasting or peddling backwards. Also crank rubs on front derailer.
Teeth are a bit chewed up on the cassette. The head squeeks pretty bad and looks like this thing had probably sat in one or three rains.
Some things I could use some help with from members.

I am new to this site and the bicycling world. Also as a fore note, I did see a topic here about the same bike in question, but I have different questions.
I recently started commuting to work (about 15 miles each way) with a Trek Antelope 800 that I got used for about 50 bucks. Until I did a little research after the fact, I did not realize that the bike was around 20 years old. It seems to me to be in excellent shape for its age. Any how, I've been riding it everyday for the last 2 weeks, and everything is fine, I am just looking to get a little more spe... Read more >>
Hey all, I have 2 bikes. One is a giant regular singletrack mountain bike with no shocks at all. My other bike is a Voodoo which has rockshox front fork. And rockshox rear suspension. I was wondering if it would be a good idea to take the front fork from the voodoo and put it on the Giant. I want to do this because my giant is my favorite bike and the one i ride the most. If this WOULD be a good idea, how would i install the front fork without ruining both bikes? Thanks for your help,

I have recently pulled my 2005 specialized expedition out of the garage.
It's in need of some repair due to it being damaged by super storm sandy. My shed was flooded with ocean water. The frame itself looks perfect but the moving parts have some rust. Including the fork, brakes, and gears. I'm just looking for replacement parts I have no intentions on buying a new bike. Please help

Hi all. I just got back into cycling about 6 months ago, and very recently got a new bike that fits me better, both in size and riding style (Jamis Coda).
Upon taking the bike out for its first "workout," (just a 20 mile ride), for the last 5 miles or so, I noticed a slight popping sound when pedaling, and could slightly feel it. Being that it's a brand new bike, I took it back to the shop, where they took apart the rear derailleur and cassette, checked for loose cranks, put it back together, and said it quit doing it. Well, when I got back home, it's still doing it.

I happend across a Sirrus A1 Specialized a few years ago. I work on cars sometimes, but don't know much about bikes. The front section seems to be intact, with functioning brakes and shifters. The middle section also appears to be intact, although new cables will be needed. The rear derailer, however, is missing. I have both wheels and they are intact. Is all I need for this bicycle is a new rear derailer? I just need to get some exercise- I'm not really a biking enthusaist- however my wife is, so I'm trying to build up romantic tension between us by doing things that interest her. Any advice ...

Hey folks. A friend gave me this frame and I am intending to build it into a road bike for myself and was looking for some advice/suggestions. Can't find too much info on the frame, seems to be a Czech company from the early 90's. Obviously I need wheels, crankset/BB shifters, derailleurs, chain, etc..Looking around on ebay I was a bit overwhelmed with the selection and price range. I am looking to spend less than $300 on the project but don't want to buy things that aren't going to work together. Do shifters/crank/cassette/derailleurs all need to be from the same group or are some in... Read more >>

Hello and thanks in advance for your help.
I recently bought my sister's bicycle so that I can start commuting by bike to work. My first attempt was riddled with issues that could be separate or may stem from one cause.
I don't know much about bicycles, and before I bring the bike to a repair shop I thought I'd field this community for some ideas on what the cause could be. My intent isn't to avoid taki... Read more >>
I have a Columbus steel De Bernardi frame equipped with Veloce (including a Veloce Ultra-Torque crank set) components, Look Delta pedals (only used a couple years) and Concor steel railed saddle. A couple weeks ago I started getting an annoying creak which seems to be related to down strokes and which sounds loudest when I'm sitting. I've used my trusty torque wrench on my crank and have checked the tightness of my pedals and seat post. But, the noise after being somewhat diminished for a couple miles came back.
Any thoughts?... Read more >>
