Wyatt Earp Posted October 30, 2014 Share XT M780 Crank (double)Look Track-S pedalsSM BB-71 The S-Tracks can creak ,try flat pedals and ride under pressure up and down, that will tell you.If the BB is in a cup, knock the cup out, clean the oxidation between the cup and the frame interface, that also sings like mad.Lastly, if your chain and cassette get worn, they can also sing like mad. fanievb 1 Link to comment Share on other sites More sharing options...
quintonb Posted October 30, 2014 Share Could also be your seat post. I would suggest stripping the bike and rebuilding and using Copper Slip on all the bolts, screws and and mating surface. Ie: Seat post, Stem, BB, etc..Aluminium is a bugger when it gets wet, or if 2 mating surfaces are dry.The material "frets", basically trying to bond itself together.The noise resonates through the frame and sometimes is hard to pin point the problem area. I live along the coast and all my bikes I build up using copper slip, never had an issue. Edited October 30, 2014 by quintonb fanievb 1 Link to comment Share on other sites More sharing options...
Fisan Posted October 30, 2014 Share When last did you replace your BB? I know you said you cleaned-n-greased it, but I often found that this was not enough. Rocky terrain + abbusive riding * (dust + sand) = BB's get replaced more regularly than tyres! fanievb and Wyatt Earp 2 Link to comment Share on other sites More sharing options...

fanievb Posted October 30, 2014 Share Thanks for the tips everyone The S-Tracks can creak ,try flat pedals and ride under pressure up and down, that will tell you.If the BB is in a cup, knock the cup out, clean the oxidation between the cup and the frame interface, that also sings like mad.Lastly, if your chain and cassette get worn, they can also sing like mad. will try the pedals, I had issues with quartz at one stage but clean and grease sorted it out.the bearing itself is in a plastic cup, but you (read I) can't remove the bearing from the cup without destroying it. I have a spare which I'll pop in after cleaning the alu casing in the frame properly. Not sure if I should try the locktite or use coppa slip or light grease coating (which I've always done). Chain is ok (measured using ruler) For what its worth the current setup is not even 6 months old (about 1500km) Could also be your seat post. I would suggest stripping the bike and rebuilding and using Copper Slip on all the bolts, screws and and mating surface. Ie: Seat post, Stem, BB, etc..Aluminium is a bugger when it gets wet, or if 2 mating surfaces are dry.The material "frets", basically trying to bond itself together.The noise resonates through the frame and sometimes is hard to pin point the problem area. I live along the coast and all my bikes I build up using copper slip, never had an issue. Cool, I'm also on the coast, so I'm definitely going to consider the coppa slip rebuild. Seat post is carbon and I'm 99% sure its not the seatpost as the creaking is worst when I'm standing. When last did you replace your BB? I know you said you cleaned-n-greased it, but I often found that this was not enough. Rocky terrain + abbusive riding * (dust + sand) = BB's get replaced more regularly than tyres! never replaced the BB, bike is not even 6 months old. But as I said I think this may be the issue, I just hoped there may be another solution. Link to comment Share on other sites More sharing options...

Martin PJ Posted October 30, 2014 Share I had problem like this. There was a problem with the hub. I found if I tightened the rear skewer very tight the creak got much better. Eventually I had to replace the hub as the axle broke in half. So there was definitely something wrong there. I found with the axle / hub problem, if I pushed down on the bike while holding the bike still, I could hear where the noise was coming from. Riding the bike, it was impossible to tell. It did sound like BB, even though it was the hub. Pacman777 and fanievb 2 Link to comment Share on other sites More sharing options...

Let's hope this is covered under the warranty Link to comment Share on other sites More sharing options...
arendoog Posted October 30, 2014 Share Interestingly the double Xt crank comes up whenever there is a crank Or Bb noise discussion.I also have a creaking noise on both my bikes ,and both have double Xt cranks Link to comment Share on other sites More sharing options...
camelman Posted November 1, 2014 Share they have been known to creak, just to add to the list...+1 on this one. Check the fox website for the recalls. Some forks have been recalled for CSU replacement due to an issue with the steerertube and crown bonding, or something like that. Had my CSU replaced by Fox. Just something to check. It may or may not be. Link to comment Share on other sites More sharing options...
Spoke101 Posted November 1, 2014 Share Fox 32 Float CTD Evolution 29", 100mm Travel, QR15, Tapered Steerer Right there is most likely your problem. I have had to warranty no less than 5 Fox Forks in the last month. It is normally the stanchion interface with the crown or steerer. (It normally sounds like a high pitched click)To test this take your front wheel out and then holding both lower fork legs try to push them together, and listen for the creak. Otherwise try your derailleur hanger where it meets the frame. If still no luck, try describe the "creak" ie: pitch, etc. I do know your pain as I have been hunting for my creak for about 3 months and it kept getting worse.Tried EVERYTHING apart from a new frame, and trust me when I say changing Rotor cranks and BB's on a Cervelo is not the easiest or fastest job. Well I eventually found this on the inside of the crank arm. Edited November 1, 2014 by Spoke101 Link to comment Share on other sites More sharing options...
