Crank alignment (possibly bent left side crank)

[Ajax Bay]

Pedal spindle much more likely to bend than a crank imho.

You'll feel a bent pedal spindle as a turning motion under your foot though.

Well guys - measured and checked the crank and........all ok!!

Checked the pedal spindle.....all ok!!

I'm going back to the LBS to get refit and see if we can narrow this down and identify the problem.

Thanks for all the info and advice

If you have an identical crank set on one of your other bikes - just swap the cranks. If the problem moves to the other bike you know it is the crank arm causing the problem. It's a 5 minute job just to swap the left crank arm.
