Hi all, after 4 years of using my power2max rotor3D+, there is some issue with the crankset getting out of alignment through the pedal stroke, as found by the mechanic after we went through a new bb and a new frame.

My question is can the rotor 3d+ at 110BCD fits a power 2 max 130 bcd spider for rotor 3D+ or should I put it can a rotor 3d+ crank arms from a 110bcd crank and spindle be used for a 130 bcd rotor 3d+ spider

The 110bcd cost half of the 130bcd cranks.

Thanks in advance

It shouldn't matter what BCD the spider is, as it is removed to fit the Power2Max unit.

I'm sure if you emailed power 2 max they would confirm, but I would think this will be no problem as well. In fact you could go with the 3d30 (or older 3df) crank arms as well since these are the same dimension as the 3d+, but a bit cheaper.

Just to add you will need a specific tool to remove the spiders, which you can get from power2max.
