For the last few weeks, my Curve D3 has been making a muted clicking noise when pedaling, always when the cranks are in the same position. Sounds like a problem with the bottom bracket or with the chainring, I thought. In case i was wrong, I scrubbed the gain and the gears as best as I could without taking the rear wheel off. (It never hurts to clean a bike.)
The noise has changed. Now it's intermittent, and the clicking is louder but sounds likes something's scraping something else. Again, not all the time and not all that loud. The bike is under warranty, but it's a pain to get it to the shop I bought it at.
Pretty weird. Anyone seen this? Thanks!
