Karl Butcher Posted April 10, 2008 Report Share Posted April 10, 2008 My bike is being abit of a shitter at the moment! theres a weird cracking sound from my BB when i put pressure on the pedals aka gaping/pedaling ( sounds like when your BB is about to go )so i swapped my SKF BB to my old Echo External but it still makes a weird cracking sound! BUT! it dont do it all the time just when it feels like it!i thought it could be my rear Hope pro 2 or a crack in the frame!the Hub feels fine when im rolling and when im hopping on the spot not long had the hub! and i have checked for cracks and i cant see any!so i have ran out of ideas what it could be! if you could help me out that would be great!

matt middler Posted April 10, 2008 Report Share Posted April 10, 2008 Could be movement between your cranks and BB, try sticking some more greese in the cranks. Quote Link to comment Share on other sites More sharing options...
wally Posted April 10, 2008 Report Share Posted April 10, 2008 Grease your bb threads and the isis splines, probably got a bit of dirt in there. Same as when your bars creak you take them out of the stem, clean inside the stem and then its fine. Quote Link to comment Share on other sites More sharing options...
Karl Butcher Posted April 10, 2008 Author Report Share Posted April 10, 2008 everythings all tight but the cranks do flex just a little bit!i cleaned it all out be for i put the Echo BB in and regreased it! so its deffo not the hub then!?

*Tom* Posted April 10, 2008 Report Share Posted April 10, 2008 (edited) Might be the pedals?, pretty sure you'd feel that though, still might be worth checking. If not, I had some creaking sounds coming from my bike when I pedaled, thought it was my canks/BB but it turned out to be my headset . . so maybe check/grease that, pretty unlikely but worth a try.

Karl Butcher Posted April 10, 2008 Author Report Share Posted April 10, 2008 My mate Jake said it could be my pedals i use DMR V8s and he said they might need some grease cos they spin like mad he said they shouldnt do that! and they movie a little it all started yesterday!

*Tom* Posted April 10, 2008 Report Share Posted April 10, 2008 Take off the end caps, undo the nut inside, the take off the washer under that you might need some small pliers to get it off, tighten up the cone so there is a tiny little bit of movement . . you need to leave this because when you tighten the locking nut up they will get slightly tighter. Then just take out the little grub screw in the pedal body, wack a load of grease in, stick the grub screw back in. Job done. Quote Link to comment Share on other sites More sharing options...
cai Posted April 10, 2008 Report Share Posted April 10, 2008 Perhaps the BB cups have come undone slightly... tighten them up and see them there? Quote Link to comment Share on other sites More sharing options...
Karl Butcher Posted April 10, 2008 Author Report Share Posted April 10, 2008 Cool i will try that! but it deffo feels its coming from the BB or cranks!Perhaps the BB cups have come undone slightly... tighten them up and see them there?iv checked both BBs and they were tight!

psycholist Posted April 10, 2008 Report Share Posted April 10, 2008 Pedal bearings or crank flex putting the chainline out would be my top two ideas... Quote Link to comment Share on other sites More sharing options...
Muel Posted April 10, 2008 Report Share Posted April 10, 2008 My best bet would be to strip the pedals down and rebuild them, you may find that the cracking is from a bearing that has shattered. Quote Link to comment Share on other sites More sharing options...

Alex Dark Posted April 11, 2008 Report Share Posted April 11, 2008 just strip down the pedals..grease all bearings or interfaces in the drive train...thats all i can think of Quote Link to comment Share on other sites More sharing options...
mintsauce96 Posted April 14, 2008 Report Share Posted April 14, 2008 Karl....Your just fat. It's your weight making your frame creak Pump grease through your pedals and see if it's that. You got a grease gun? If not we'll do it at me bro's work Tuesday Quote Link to comment Share on other sites More sharing options...
sstein Posted April 14, 2008 Report Share Posted April 14, 2008 It is very, very unlikely that it is your pedals, I have about 5mm of up/ down movement in mine and that is just annoying but causes no squeaks or problems. Take your bb out and regrease the threads, put it back in and make sure that it is properly tightened, then use an overly large amount of grease on the axle/crank interface and tighten the crank on to about 45-50NM-1. That should stop it.You should also regrease your pedals just to make them last longer, however you do not need to strip them down as someone said.
