Finally! After shortages of Vector/ASSIOMAs across the market, PowerMeterCity is all stocked up and raring to go with the Favero ASSIOMA DUO (Review) and UNO models. You can get them NOW, from stock.
That would be my personal power meter pedal of choice. (link to: the5krunner.com)
There is limited stock of the rather pretty Garmin Vector 3s and stock of the dual-sided Vector 3 is still on backorder.
PowerTap P1 single/dual are generally available in any case.
