Sounds like a manufacturers defect.
You can ignore Hillrider. He's a troll. I'm betting it's either toasted bearings or a loose crank arm, neither of which would be a manufacturer's defect.bobbynopedals said:To clarify:Â The original recording was done whilst riding the bike round the block to the front of our house. (I have since tried weighting the pedals with the bike stationary) We have had the bike a year or two maybe, so not sure how possible or likely a manu' defect is now?Â [the bike has spent most of its life wrapped in a blanket in the garage(which is very well insulated and dry)Â Â and then it gets brought out occasionally and put to use on some beachy/woody trails mostly. I gave the spokes a little pluck when i was first debugging this, they all sounded good.
i think so too, happened to me once, very similar noise, mine was broken but i could still ride and the solution was a complete replacement,doctorold said:I have listened again and I have to concur with others. Â That has got to be a bottom bracket problem.
Smart idea, taking it to the shop. Doctor's normally don't make diagnoses over the telephone.Originally Posted by bobbynopedals .
No kick stand on it anymore I'm afraid, and this is on hold until tomorrow, My crank puller, which I haven't seen for a while, has gone AWOL, so I'm gonna roll down the LBS tomorrow and see what they say and pick one up.
My money is on the crank arms.
Hey, that was an easy one. For future, you can get a good feel of the BB bearings by just dropping the chain off the inside chainring and then turning the crank slowly with one finger on the crankarm. Bet if you had done that, you'd have been shocked by how "notchy" the bearings really were. I do this check every now and then, when cleaning or lubing the bike, as it only takes a minute.Originally Posted by bobbynopedals .
Well, the saga has came to an end... it was the BB bearings.some had completely shattered.
I've no idea how it could have been so tight and smooth with all them bits in there, but it was.
Thanks a lot for all the help, 'tis much appreciated.
