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 made a post a long while back looking for info on replacing my derailleur and painkiller was wonderfully helpful in providing info about how serious the problem actually was with more than just the derailleur.
Now I've finally arrived at a point where I've got the time and money to bring my old bike out of the garage and back to the road. I originally received the bike from my uncle in rough condition several years ago. It hasn't changed much since aside from b... Read more >>
I have an old Cannonade Bad Boy. Frame was made in the US. The paint has bubbled all over the place and the alloy has oxidised underneath it. I want to strip it - check the frames integrity and then re-spray it if it's not compromised.
Before anyone starts - I'm aware how about intensive stripping frames by hand is. I've done this with a couple of steel bikes.
What's the best paint stripper for an alloy bike? Nitromors? Is there something better?
What's the best primer for alloy? Have read this is good:

Hello from NC! Have been away a while....
Update of the 2 bikes I overhauled 1.5 years ago...
Peugeot got damaged during move, and Mayflower didn't cover it, even with my appeal... So I dis-assembled derailleur, bent it back, and re-assembled it.. Rode it a few times..... Appears to be normal.... (I've had No issue with the ceramic bearings in Peugeot)
Gitane did not get damaged during move, but still throws chain on reverse pedaling (something that caused my mom to stop riding in 1980's). My overhaul, steel bearings made chain issues better, but not p... Read more >>
I have a Dawes Discovery 201eq gents from 2011 that I want to fix up after a couple of years without use. The goal is to get it into good enough shape that I can use it for commuting and some training. I know it's not ideal for training, but I can't afford a road bike at the moment. Also I need the Dawes bike for occasional family trips (with kid on the back) so that's why I want to fix it up rather than save up and buy a road bike right away.
Here are the original specs for the bike along with some status of them:
Frame type: 7005 al... Read more >>
I like the current frame of the V2100, its why I purchased it last June. Also, I am by no means a "serious" mtb'r and former dirt/vert rider, but being older now I generally ride in the city but dont care much for road bikes as sometimes I like to trail ride, so, that being said I do plan on upgrading everything on this frame, but not with any expensive components ofc.
My main question - Are there any decent BB/cranksets that will fit this frame...SRAM...anything other than the stock garbage, and yes I noticed that all hardware and components are junk.
I have seen other V210... Read more >>
About a year ago I bought a pair of Venzo road shoes on e-bay- most comfortable shoes I've ever owned. The rubber inserts on the underside have worn too low to keep the cleats from rubbing and squeaking, The inserts are removable and have a screw securing them. Does anyone know where I can buy replacement rubber inserts of this type?... Read more >>
I recently started having a clicking noise from the rear axle area of my bike. It is a Schwinn Link (City series).
It doesn't start until riding about 4 miles. It is like tak tak tak and I feel it in the pedals and frame. It has a frequency of about 2 clicks per second. It is like someone is lightly tapping on the rear axle with a piece of metal. It only happens when putting power to the pedals and gets more pronounced the harder I pedal. It comes and goes but after riding a long time stays. If I freewheel I can sometimes get it to go away. This bike has 7 gears on the rear wheel. it is ... Read more >>
As I start taking measurements of (What I believe is a Peugeot U09 from 1980) for the upcoming "thrift shop fork",
I came across something that I may have posted before, but thought, what the heck, see if any information on this has changed.....
Believe it or not, the original Paper Tag on the bottom of the frame by the crank, is still there and legible!!!
On the Paper tag is the following: 5286275 038157
It also has a number stamped of the flange for the rear axle.
On the metal frame is stamped: B0018618

I have just acquired a Cervelo Soloist 2006, has the Ultegra 6600 groupset. It was making a clickity grinding sound whenever I'm on the larger 2 or 3 sprockets (doesn't matter which chainring) when I'm pedalling hard and fast.
Anyways, took my crank, chain rings, and bottom bracket off to clean, inspect, regrease and retorque. Greased my new pedals and torqued them on. Adjusted my front derailleur and rear derailleur (have adjusted the B screw as well to give plenty of slack). Still no good. I've even fully slackened the lower limit on the FD so there's plenty clearance left and r... Read more >>
We moved from Chicagoland to Mountains of NC in July....
My 1980 Peugeot U09 front Derailleur got bent way out of shape by the movers...
Knowing the availability of 1980 era French Simplex parts, I had a day while I awaited the remaining furniture, and I took the Front derailleur apart, carefully straightened the metalwork on a flat metal vise to the point where (I felt) it was back to "normal", and put it back together and adjusted it.... and in about 8 hours, it actually worked!! Tested it with 15min ride... Seems OK...
I eventually had to pu... Read more >>
It is with heavy heart I come to you today. I swapped some wheels from a bike my daughter and I bought. Cleand up the DAc50's to put on the bike. Decided to give her Spec Ruby a real good clean before I put the wheels on. It's a good thing I did. See she had a crash about 2 weeks ago and destroyed her front rim. I had a rag with a light degreaser on it and wiped over the top tube where it revealed a rather good sized crack at the head tube. Took it to the LBS I trust and they confirmed it is a crack.
Have done some checking around and found some repair options.... Read more >>
Can someone explain me what those holes are made for?
they are on the both sides, dimensions as shown in the pictures...

Hi everyone. I am new here and to cycling in general. I got myself a Giant Cypress (2013, I believe) bike in Arizona. After two years, I needed to move to Atlanta, GA so I had my friendly local bike shop box up my bike and had it shipped away. Here in Atlanta, I don't have a car yet and the days are pretty hectic so I haven't had the time to hit up a local bike shop to have my bike re-assembled.
I'd like to do it myself if possible and I'd like to know what tools are needed to re-assemble the bike? I currently have an adjustable wrench, a hex wrench set, and all sorts of Ph... Read more >>
Recently received this bike from the parents since I moved into the city. I tried to take it to a local bike shop but they said it was better to just buy a new bike instead of trying to update.
Sorry to sound repetitive but I am new to bicycling and have no idea what I am doing. I am willing to learn and I have patience. Yes, I understand that I could more than likely get a bike on Craigslist in running order for the same price for what I'm going to put into this project. I want to be able to ride something that I have built up with my own hands. Anyways onto the bike.

Hi guys, So my housemates for my birthday decided to buy me a bike as my work is quite far and buses and owning a car are far too expensive for me. However it is very much a bike bought on a student budget and needs some fine tuning and I was wondering if you could help me. I am a complete novice at everything bicycle related and am posting on here to see if I could fix these issues instead of taking it to Halfords and having to pay quite a bit for the repairs.
I have been browsing around this website for a while and there are a few threads which seem to be talking about what I n... Read more >>
