I was hauling down Broadway & when I hit Times Square, I hit the brakes (locked up my legs) & felt/heard this weird noise. It was a sort of ratchety sound. Like when the cog comes loose (I doubt it did). I pulled over & checked the crank arms which seemed to have play. So I walked 2 blocks to Metro & had them check the bike.
They brought it back & said 3 of my chainring bolts were loose, as well as both crank arm bolts. They tightened them up, no charge.
OK, got back on the horse & continued down to Union Square to pick up a bar/stem set from another member. On the ride back home (151st Street) I started hearing a creaking noise (last time it creaked like this was a loose pedal) & more play in the left crank arm (this arm had come loose like 4 times before, to the point I had to start riding with an Allen wrench).
Got home, tightened the pedals, crank arm bolts & there is still play. Feels wobbly & creaks when I pedal. Needless to say I think the left arm is shot. Funny thing is, when I move the drive side arm I can see the chainring move a bit, along with the whole bottom bracket (frame part). What's up with that?
Is it possible the BB is messed up? Will I just need a left arm, or a whole assembly? This sucks, I can't ride 'till this is fixed.
Thanks for reading this.
