Bicycle Noises?



Yeah i got this moutain bike very recently and it was great at first. Till one day, i think my friend (hes quite plump) sat on my bike and now my seat is making some noises. Im quite sure its the seat cause when i stand while i bike i only hear my left pedal making some noises too -.-. So in conclusion: my bike is making 2 noises, 1 from my seat the other from my pedal. So any bikers have any tips to silence these noises? Thank You for sharing, cause i need to tell the service man at the bikeshop my problems but i find it hard to comunicate as i dunno the terms of the bike parts etc. Thank You for reading ^_^ your reply is much appriciated.

Depending on what kind of bike you have, (yeah it does matter) and what seat you have, it could be one of a few things. 1) Remove your seat post ( the thing the saddle sits on top of, usualy held in with a quick release or a 5-6mm hex bolt) and grease the snot out of it with pretty much any wheel bearing grease. Reinstall. 2) loosen the bolt(s) that attach the saddle rails to the seat post (under the seat) and grease the threads of the bolts(s) and re tighten. 3) sometimes the rails of your saddle will loosen in the plastic molded holes of your saddle and this can cause squeaking. There is realy nothing that you can do about this longterm other than replace the saddle. One last thing, I have seen a bunch of Gary Fisher bikes and other good quality aluminum bikes develop a squeak or a click that some shop guys cant hunt down. What happens is if an extra long seatpost is used and it is not extended very far out of the seat tube, the base of the post will rub and knock on the inside of the seat tube. This is only heard when seated, and you will hear it both coasting and pedaling. The fix is to remove the seat post and cut off whatever material is not needed on the end of the post, being careful to leave the minimum length in the seat tube for safe riding when the post is fully extended to comfortable riding position. Give those a try. Source(s): many moons at the bike repair stand.
pedal - maybe bearings need replaced. seat- thats hard, no moving parts, my seat squeaks at times and i just have to put up with it. if its an old one think about replacing it. or try something like GT85 or WD40 maybe.
try putting a little bearing grease on the seatpost, not alot, just enough to get it slick. it will eliminate the friction between the seatpost and the seat tube. the pedals may need to be replaced also. it sounds like a bearing problem. it could also be your bottom bracket. try to wiggle the crank arm back and forth (pushing it towards the frame) if it moves, then you have a loose BB cup. take it to you shop and have em tighten it up.
Well the left pedal could be the Cone Bearing mainly if you have a three peice crank. The seat i would just tighten it and oil it.
