|Noisy FSA BB?||OffTheBack|
Jan 1, 2004 6:59 PM
|My bike is making a clicking sound when I pedal that is driving me nuts. It's not the chain, cassette, or wheels. The chainring bolts are all tight. The only possibilities left are the FSA 'platinum pro' BB (not the TI version) or my Time Impact pedals. The BB is new and tourqed to spec.
Anyone have noise or other problems with an FSA BB? Thanks in advance for any help.

|Odd clicks that sound like they are coming from the BB area often are not. Just to clarify before I try to help you tackle this one... how are you sure that what you ruled out is actually ruled out?
I have the Platinum Ti BB and have never noticed it making any noise, but you can always take it out, clean it and put it back in to see if that helps. Once you have it out, inspect the cups to make sure there are no cracks, and check out how the bearings feel and look.
Also, what wheels do you use? Are you using Open Pros? If so, that is most likely the actual cause of your clicking sound. they click at the rims. So that just ties into knowing for sure if what you eliminated is actually off the list.
Other than that, you may want to get new crank bolts and test those. Get some steel bolts to fit that BB (you may have to call FSA to get them as most of theirs except their freeride BB's use alloy bolts) and torque them down to spec. See if it's not the bolts.
Sorry for the vague list of to checks... but wierd creaks and clicks take a lot of work to narrow down.

|Replaced the chain with a new one... same noise. Switched to a backup pair of wheels (neither pair are OPs), with a different cassette... same noise. Removed the cleats from my shoes, put loctite on the little bolts that hold the brass cleat to the metal plate, tightened them down ... same %$#@$#@! noise. It only happens when pedaling, not when coasting, and when I put the bike on a repair stand and spin the cranks by hand, I can't hear or feel anything. I'll try swapping pedals this weekend & if that doesn't do it I'll try the crank bolts. Thanks for your help.|
|How about saddle rails?||Dave Hickey|

|Does it happen when you're sitting and standing? I had a clicking sound that turned out to be the saddle rails.|

|A little silicone lube on the front of my saddle rails fixed my bottom bracket noise.|

|Iagree with Russ. Also check the tightness of your front skewer. I recently had a creak that I swore was my bottom bracket. I check everything out including the front skewer and found it to be not as tight as it should have been. A quick re-tightening and the creak was gone.|

|Does your frame have a bolt together rear triangle. Many of the frames with carbon rear ends are bolted in the area of the rear dropout and the joint may get noisy. If you remove the bolts and put a film of grease between the parts, it should not make noise there. If you do not have this type of frame, this info may help someone else.|

|Another vague source could be the front derailleur if it's a clamp type. If the clamp is a bit loose or if there is a buildup of gunk between the clamp and the frame, this can cause the derailleur clamp to "rock" as the lower seat tube flexes under load. You cannot see it but you can certainly hear it.
I never believed it either until I had it happen to me - removed the front derailleur, cleaned the inside of the clamp and the seat tube, reinstalled everything and my mysterious clicking was gone. And this after I had tried EVERYTHING else, including a bunch of stuff not listed in the previous posts.
|Thanks for everyone's ideas - I'll post an update Mon (nm)||OffTheBack|

|In addition to the suggestions of the other posters that the bottom bracket may not be guilty I've discovered loose bottle cage rivnut(s) and/or sports drink gunk buildup around the cage/fastener/downtube to do the same. Pull the cages to check, and if it's the sports drink really hot water/paper towels breaks it down easily.|
|UPDATE - found the source of the mystery noise!||OffTheBack|

|It wasn't the BB ... it was my Time Impact pedals. Apparently the bearings are shot after 3500 miles. While I'm tremendously releived to have finally identified the source of the noise (and to cancel my rservation at the loony bin), I'm a little disappointed with the life of these bearings. Must be the price you pay for the low platform height is increased side load on the bearings?
Thanks again for everyone's help. Happy (and quiet) riding!

|Have you emailed Time about this? I ask because I'm pretty sure (90%) one of my bikes has the same issue - I haven't really had time to check out the click completely though.
Was wondering if Time says there's an easy fix for this. FWIW, the Impact S's on my 2nd bike that are noisy only have about 2k miles on them.
I've sent them an inquiry email about mine asking if replacement bearings or a service tool are available. If I hear anything, I'll start a new post so that other Impact users know what the resolution is.
