Another ticking noise thread…

I have had an irregular ticking sound coming from the pedal – bottom bracket area since this summer. The ticking doesn’t follow any particular pattern. It can start right away or sometimes it takes a mile or two to get going. It only makes the sound when I pedal and going faster or slower doesn’t make a difference. I can’t duplicate the sound just by turning the crank on a workstand I have to be riding it. I believe I’ve checked all the silly stuff like loose spokes, cables etc.
It started when I transported my bike upside down for a vacation. I also put on a new pair of cage pedals at the same time. At first I thought it was the pedals, so I inspected them and made sure that everything was tight. However, the sound remained. I took it to the LBS and had them replace all the old cabling and lube everything, which needed to be done regardless. Still the sound remains. Finally, they replaced the bottom bracket (I’ve had a similar sound on some other bikes and replacing or lubing the bottom bracket has always fixed it). Yet the sound remains. I suppose I could replace the pedals just to make sure. Is it possible the LBS didn’t install the bottom bracket correctly? Or is there something else I should consider? FYI…my bike is a ’03 Trek 7500.
Somebody last month posted a similar problem, but I can’t find his post. I would like to know how his turned out.
Any ideas…HELP!

Such noises, as you likely know based on all the lubing you've done, can sound like they are coming from one place but are coming from elsewhere. Since you have gone as far as replacing the BB, my guess would be that that is not the problem. My best guess at this point is the saddle area. Over tightened seapost collar bolts, loose seatpost collar bolts, dirty saddle railes, and dirty/loose saddle clamp bolts have all been in my experience causes of annoying creaks. The noise starts at the saddle but echos down the seat tube so they sound like they are coming from BB area. Give the whole area a cleaning, regrease what shoud be greased, and make sure bolts are all torqued according to specs.

I had a similarily frustrating sound that I tried to get rid of once. Certain that it was coming from the bottom bracket or pedal area, I dismantled, inspected and repacked everything (BB, pedals, crank bolts), to no avail. Finally, I pulled and greased the seatpost. Bingo. No more ticking. All that to say, I second what DOS has said: Check the saddle area.

If it only happens when your pedaling on a bike, and you wear normal shoes, as cage pedals would indicate, it might be your shoelaces. It drove me nuts before I first realized that the aglets were what was making that noise.

The last time I had that phenomena, it turned out to be the chain. It was stretched, according to my LBS (under warranty). They said a bunch of bad chains had been turning up. It was "new" but stretched. I'm betting it was just bad. Anywho - with a new chain, courtesy of Trek, the ticking noise was gone.

Not saying this is the case here, but add that to your list of possibles.

Thanks for the replies. I really think it is something in the pedal - bottom bracket or at least the power side of the bike. I checked the odd but easy stuff already...seat, saddle, shoe laces. The chain is a possibility, although I lubed the crap out of it. The other bit of infomation that makes me discount some of the suggestions is this...I can do a kind of slow pedal as I'm rolling along and can hear the ticking as the pedals are turning around. The ticks don't alway occur at the same point in the rotation, but as soon as I stop pedaling it goes away.

Well, other peal specific possibilities.

-- Cage rubbing against shoe -- rmove cage and pedal to see if clicking remains
-- Cage fasteners (whatever is holding cage to pedals) loose/too tight/noisy for some other reason
-- Pedal axle threads not greased properly (I suggest anti seize).
-- Something on cage ticking on crank arm
-- pedal hitting bit of front derailleur cable that extends beyond the fixing bolt

Clicking noises can also come from spokes that rub together when riding. To see if this is the case, crank the pedals with no one on the bike. If the clicking noise is gone...it's likely a pair of spokes that are rubbing together.

Find which two, and either use steel wool to smooth them out at contact point or put a small piece of tape between the spot where the spokes touch.

Easy check, swap the pedals. If nothing else, it'll stop you worrying about pedals though in my case, it led to me rebuilding the things

I had a similar problem. I have an integra BB that has to be lubed properly and tightened much tighter than I would have thought. I also have shimono combo pedals that were a souce of clicking as well. As Europa suggests -eliminate the pedals by swoping them for anything else. Your LBS should be willing to do this. My noise was my pedals - the clip mechnism was marginally tight. A quick twist of a screw driver and the problem was gone. Quiet.

oldiebikes is onto something. Check the wheel. Swap it out with a spare to check (assuming you have a spare).

It surprises me to find how few people overhaul their pedals these days. I've always considered this a to-do on a yearly basis - or more often depending what I've been doing (riding off a pier lately?).

do try a different wheel if you can. i think the fact that the ticks don't happen at the same point in the pedal rotation might be important. so maybe it's something in the freehub body, maybe a misaligned pawl or a missing ball in one of the bearing.

Thanks again everyone. I'm leaning towards the pedals now. I was digging through some spare parts and found a completely new cage pedal I didn't even know I had. I replaced the left pedal and much of the noise went away. I'll probably invest in another new pair and replace the right as well. Hopefully that will do it.
