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.
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 >>
Could someone help me out? I recently purchased a new single speed bike sprocket. I put it on my bike and I had to make the chain smaller. Anyways I got everything put together and its as if the bike doesn't have enough tension when you pedal. like when you pedal it feels like the chain isn't even on. the cranks spin almost to freely....

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 >>
