Favero Assioma Duo £719
Favero’s design is compatible with the Look system; the red version of the cleats are supplied in the box.
The power meter parts sit in a housing next to the pedal body. There’s no specific torque required — simply fit them to the crank using an 8mm Allen key as you would any other pedal.
Having all the electronics housed in one place on each pedal also has the benefit of keeping the look of a normal pedal. Unlike the enormous Powertap P1s, the Faveros are not too bulky. They have a stack height of 10.5mm, like a standard road pedal. The rechargeable batteries are a particularly nice touch.
The Faveros were initially confusing to set up. It is possible to pair the slave pedal (right hand) instead of the master (left), which gives unintelligible readings. If the two were hardwired in the same way the Powertap P1s or the Garmin Vector 3s are, things would be more straightforward.
In terms of battery life, the pedals had about 50 per cent charge after three big turbo rides, two five-hour epics and a handful of morning commutes. Favero claims its battery indicator is more accurate than any other non-rechargeable battery powered unit, so 50 per cent means 50 per cent.
We found the spring tensioning screw at the rear of the pedal lacked finesse. It would wind right out of the pedal body rather than release tension and it wasn’t possible to max it out in either direction. In addition, the pedal isn’t weighted correctly so that if you miss clipping in, it spins round until you kick it the right way.
As for accuracy, Favero claims +/- 2%, which is better than either the Powertap P1s or the Garmin Vector 3s. When compared to an Elite Drivo smart turbo, they were around +/- 10-15 watts.
To sum up, you’re getting dual-sided measurement for a seriously good price. The pedal’s design isn’t flawless: it’s weighted frustratingly and the tension screw is a bit hit and miss but the pedals are lightweight, have rechargeable batteries and a normal stack height.
