hello, so here I ago, my recently purchased off CL Giant Butte started producing these annoying clicks on each pedaling move
it has biopace crankset so initially my thought was that the chain touches FD as the crankset isn't round, but no, I reattached everything, tuned it fresh and clicking still persists. I would say there are even two clicks each pedaling cycle, one louder, one not that much. I checked chainwheel bolts - all are tight and secure. Checked pedals - both spin smoothly and don't click. I also checked the seatpost and greased it, no clicking coming from it. Checked for cracks - no visible cracks so far.
So that clicking happens only when I SIT on a saddle. And it clearly comes from crankset area, I even feel it through pedals. If I stand on pedals and ride like that - no clicking is happening. If I just spin pedals while off the bike - no clicking either. When I go uphill clicking becomes much louder and distinct. When I cycle slooowly, clicking almost goes away.

Any suggestions? Should I take it straight to bottom bracket and replace it? Or it still can be something else?
