Mysterious Clicking Sound with NWT
Hi all, I posted this problem in the Bike Mechanics side a couple of weeks back but no joy there. Am going to see if any of the folding crowd might be able to help out.
I purchased a Bike Friday New World Tourist bike about a year ago and have only done about 2k on it so far. It seems to have developed a soft/dull clicking sound that you can feel through the seat stem and pedals. I can't seem to feel it at high speed but I don't know if that is because I am going fast and can't hear/feel it or because it only manifests itself at low speeds (3-9 kms/hr). When I walk next to the bike, I can't hear it; when I walk the bike with my chest on the saddle pressing down on the bike, I can't hear it. It only manifests itself when I am on the bike with my full weight. It does not matter if I am pedaling or not, nor does it matter if I am putting any pressure on the pedals. Nor does it matter what position the pedals are in, whether at 12-6 or 3-9 although I suspect at times that it is more loud at certain positions.
I've checked all over the bike for anything that may be out of place but nothing. I've held the bike up and got the wheels spinning but nothing. Like I said before, this only seems to happen when I have my full weight on it.. The sound speeds up the faster I ride and slows down when I slow down so I keep thinking it has to do with the drive train somewhere. I'm not sure if this has anything to do with the fact that the bike is equipped with a Rohloff hub.
Any ideas would be greatly appreciated because this sound has been driving me nuts for the past month and I worry about riding the bike with an unresolved issue. Thanks!
