    Odd squeak/rumble when starting out and standing on pedals

    Hi all,

    Early 80s Centurion super Le Mans with what looks to be all the original style bits on her.

    When I start out and stand on the pedals I can hear a small squeak and feel a slight rumble through the handlebars. after a revolution or two it goes away.

    Grease/change the ball bearings in the front fork? Other suggestions? I've lubed the pedals and around the headset with 3 in 1 and at first it seemed to help but that may have been wishful thinking on my part. The headset does not wiggle when I move the handlebars and turning feels fine...

    I can live with it if I have to. Would like to get the bike running as much like new as possible without spending a fortune. It's a sweet little ride and I really like it as my Friday cruise-to-work bike.

    As always, thanks in advance for the wisdom.

    Check the crank arm bolts. They make creaking noises when slightly loose...

    I had a squeak during harder pedaling that turned out to be the spd cleats rubbing against the aluminum pedal cage - I was wearing cleated shoes with old school toe clips.

    Recommend you remove the front wheel. Turn the forks to one side, then the next. If it binds, you have a headset issue - and will need to tear it down at the very least. Old grease and dirt will have to be cleaned and replaced with fresh grease, and it's usually best to inspect the crown race and bearing cups while you have it cleaned out. If one of the cups is cracked or pitted, or the crown race is pitted, the individual parts or headset will have to be replaced.

    The most likely suspect here would be pedals, though. If you have another set of pedals kicking around, try swapping them out. If the squeak disappears, the pedals have an issue, and will require the same treatment as just mentioned for the headset.

    Bottom bracket might be an issue, also, per verktyg's comment.

    When is the last time stuff with bearings got new grease? Pedals, HS, BB, etc? If it has been years, great excuse to go ahead and do this maintenance. Grease does not get better with age.

    3 in 1 oil is not adequate. You should disassemble, clean and regrease all bearings. Headset, bottom bracket, wheels and pedals. Replace any that are galled and worn out. It should be better then. Vibrations and noises have a strange way of traveling throguh the frame. You only feel it in the bars because you're not touching the bike anywhere else. May be the Bottom Bracket

    First thing I'm checking is BB. Pull it apart, clean and regrease. How much moreso if there is "feel" being transmitted through frame.
    Having a flat tire as part of the total cycling experience is highly overrated. Knowing how to fix one quickly is not.

    +1 to this.

    Don't be scurred to try your hand at servicing your BB, either. Only need a couple special tools (lock ring wrench, crank puller) other than your basic hand tools to do it. And if the grease in there is as original as the other bits on the bike, you're gonna want to clean it out for sure.

    Thanks, all. I just got the bike a few months ago and suspect the grease is as old as the hills.

    Good excuse to get your hands dirty.
