SOLD Rotor 2INpower 170mm Power Meter
Quote | Reply
*** SOLD ***

Rotor 2Inpower Power Meter. Special Aero MAS spider version. Rotor 3D+ cranks with 30mm spindle.

170mm crank arms. 5 bolt 110 BCD (the only BCD Rotor makes).

Less than 500 miles because this was on my TT bike and I barely ride it.

This is the same PM I run and love on my road bike and I’m only selling this one because I changed crank length on my TT bike to 165mm.

No magnets included because no magnets required.

I find that watching the soft pulsing light of the magnetic charging cord (snaps on like a Macbook - no coin cell batteries required) is oddly soothing.

$750 PayPal and shipped in CONUS.
