- Bicycle is a year old fairly cheap road bike with ~1000 miles.
- Transmission is 2x7 speed-derailleur design, so 14 gears total.
- Clicking noise somewhere near the drivetrain-ish area when pedaling uphill or somewhat aggressively.
- Started happening recently after I changed my rear inner tube.
- Clicking/popping is periodic but much more than one crank rotation.
- At worst, there is a loud pop felt in the pedals and the chain seems to skip.
- Worst in gear 4-5.
- Not very noticeable in gear 1 or 7.
- Not noticeable when freewheeling or pedaling backwards.
- Still pops/clicks when pedaling standing instead of on the seat.
- I took the rear wheel off and put it back on to make sure the axle is seated properly.
I'm now out of ideas for what it could be. I'd really appreciate ideas.
