Hey fellas I have a question. I have a 2008 Specialized Sequoia Elite and have had a click sound since a few months after I bought it. When I am pedaling I have two clicks that happen in around the same space on each revolution of the pedals. I thought it was a pedal but I have replaced them with clipless pedals and it is still there. I also noticed while riding if I push forward on the bars I can get a click some times.
Now what’s weird I was at the lbs last week and we put the bike on the trainer to look at a fit issue and there was no click at all. With that said if there was no clicking on pedal rotation on the trainer but there is on the road what could it be?
Thanks for your help. it is strange having to ask these questions I am a mechanic by trade with 20+ years experience working on anything from Yugo’s to Winnebago’s but I’m ignorant in working on the bicycle. I have much to learn on what tweaks to do on the bike to make everything work smoothly.
Thank you for your time.

I had three incidents were a "click" ended up being:
1. the saddle - it would click when I pushed down on the pedals
2. a loose stem - it would click when I pushed forward on the bars.
3. a zipper on a jacket that I wore hitting on the top tube (this one drove me nuts and I thought I was an idiot after I found the reason)
(These where on two different bikes).
I hate unknown little noises from by bike. Good luck!

Could also be the headset interface with the frame, the cables in the cable stops near the head tube, the bottom bracket, loose chainring bolts, bottom bracket/crank interface, saddle or seatpost, a bent tooth on a chainring, crank hitting the excess cable from the front derailleur....
I know I have heard a click at the headset when i pushed forwarh hard but I wouldnt think it would click perfectly as I pedaled. as far as a saddle click it should have happened on the trainer as well right?

'as far as a saddle click it should have happened on the trainer as well right?"
Probably but riding causes more vibrations and little bumps etc. IDK I think it is worth taking a look at that part.
On the trainer the only "part" that doesn't move is the front wheel right? Have you looked there closely?
The problem with "clicks and creaks" for me is that the noise is transfered through the bike and it is really hard for me to find the source.
yeah its really hard for me to tell where it is coming from.

As has been stated clicks can be hard to diagnose and can come from seemingly unlikely places. For example, I was having a similar problem. Turns out a little dirt had gotten between the stem and handlebar. After cleaning it out and reinstalling, it went away. Take apart, clean, and reinstall these little things: stem/handlebar, stem/steerer, saddle/seatpost, seatpost/seat tube, etc. Do one at a time if you care to know exactly where the problem was.

I had a click that was perfectly synchronized with my pedals. I lubed and adjusted the pedals, cranks, bottom bracket bearings, and shoe cleats to no avail. As a last resort, I took out the seat post, greased, and replaced. The click was gone.
Sometimes only the process of elimination will lead to success.
Does the click exist while coasting?

no only while pedaling

I had a similar problem once, and it was very difficult to find the cause. I would hear a clicking sound when pedaling hard or pressing down hard on the handle bars. After monkeying around adjusting different parts of the bike to try and eliminate it, I decided to strip the bike down to the frame, and start over, making sure that everything was greased and as tight as it should be. When I pulled the cranks, I found the problem: a crack was forming where the seat tube was welded to the bottom bracket.
I think in these cases, it pays to take a careful look at every part of the bike.

Check this out and see if it leads you to a solution and then let us know. http://sheldonbrown.com/creaks.html
i disassembled the bottom bracket to see if i could find the culprit last week. removed the chain and cleaned and re lubed it. pulled cranks and pulled the bearings. cleaned and lubed as good as i could and reassembled.
i took it out Sunday for a leisure ride with my son and for 3 miles it was beautiful. no noise nothing. and then it started all at one time i had 3 clicks when push down on the left pedal but only one click if i took the pressure off of the that pedal. hmmmmmmmmm i even thought i could feel the click coming through the pedals and shoe. any thoughts?

I've had clicking from loose crankarms and from bad pedal bearings. Neither was evident unless I was riding on the road applying my full weight on a pedal stroke.

Tighten and grease. Pedal threads, headset, drop-outs, loose spokes, shoe cleats.
