Selling a CycleOps Powertap SL+ G2 Rear Hub 24 spoke Power Meter. It fits 10sp casettes but is the 15mm axle version that can be upgraded to 11 speed by replacing the freehub. The unit is currently mounted in an older Hed Jet 4 carbon wheel. The power meter works great but the rim exhibits a "noise" that occurs once per revolution when ridden. It is the opinion of my LBS that the noise is potentially structural in nature, perhaps something in the bond between the aluminum braking surface and carbon fairing. I elected to stop riding the wheel and have upgraded to a newer wheelset and G3 powermeter. I didn't remove the Powertab from the wheel as the current set-up may have utility for a stationary trainer.
