I have a dual sided Pioneer power meter on a Dura Ace 9100 crank for sale.

172.5, 52/36 rings "mid compact".

Left power meter is good.

Right power meter is not so good.

Tested while mounted to a Kickr Core in ERG mode, "pedal monitor" mode, first left only power doubled, then right only power doubled.

Left reads within 1% of ERG power

Right consistently reads 15-20% low.

Crank and rings are in good shape, with expected scuffs etc from use.

So unless you're handy with electronics, consider this a Pioneer left arm power meter plus complete crank. I will configure it as such before selling it.

Comes with the SGX-CA500 head unit, which is needed to configure the crank.

Make an offer.
