Stripped crank - specification please?

[bret]

My left crank arm says "Driveline" and 155mm. This is from a 2021 model Q45.

Please tell me the complete specification for a replacement. I mean if I'm looking at a set, what is the BCD of the spider on the right, as I may need to buy the entire set to get one.

Any other pertinent details to ensure I get a replacement that fits? Please let me know so I have them when I'm calling around to bike shops.

Thanks in advance.

Where are you? I switched mine to a double so have the complete crank (arms, chainring, and guard).

I'm guessing shipping would cost more than a new one.....

Likely.

A methodical approach allowed me to pull the crank and mount the pedal-assist sensor, and there's no problem with the square taper, so the pressure is off. Thanks, though.
