Bespoke Founder Barry has been putting the Assioma Duo
through their paces:
I have used a lot of power meters over the years; at least 4
SRMs, a Powertap hub, Garmin Vector pedals and 2 crank-based
I still prefer crank based PMs (mainly because I am a total snob
and think they look the most Pro - tragic I know!). But given that
I test so many bikes now I am becoming more and more a convert to
Garmin is the best known one out there, and Powertap do a highly
regarded P2 pedal, but it was the small Italian brand Favero that I
was keen to try for the first time.
So far I have 3 weeks on them; including 950km in Portugal.
Spoiler alert: They have been flawless.
They are ridiculously easy to put on and set up; just like a
normal pedal, no fancy tools or alignment required. Pairing is with
your phone; as is calibration. I did some intervals with these
compared to my SRM and they were within 1 watt of each other, so
accuracy is good.
They are fully rechargeable and are meant to give 50 hours of
use before needing a charge; for many people that will be once a
Our ride time in Portugal was 35 hours and they were still
showing plenty of battery life left from a single charge.
These are 1/3rd the price of my SRM, and they have capabilities
the SRM does not such as left/right power split and the Garmin
Cycling Dynamics (Torque effectiveness, pedal smoothness, rider
position etc). To be honest I am not sure of the real world use
case for some of these data fields; but Left/Right balance is
definitely useful, especially to track changes in balance under
different intensities and duration (i.e. does your L/R power
balance get worse as you tire).
The main reason I was interested in trying these was the near
universally positive reviews they received. People such as DC
Rainmaker and GP Lama probably do the best tech reviews out there -
and both of them use Assiomas as part of their baseline set-up for
accuracy when they try new power meters. And if its good enough for
They are every bit as good as everyone said they would be. Very
good value for money, easy to use and set up, very accurate and a
with only minimal weight penalty over standard pedals (probably the
lightest way to get power on a bike).
The only downside I've found is that if you prefer Speedplay
pedals or SPDs (as I do) you are wedded to the Favero Look
That one issue aside it's amazing how good these are. When you
look at the SRM Exakt pedal at £1200 you realise the Favero is
almost half the price, more accurate and infinitely easier to set
up. Literally a case of plug and play.
Given training and riding with power is probably the second best
investment you can make in cycling (after a bike fit) I predict within 3 years almost all
bikes sold with have some sort of Power Meter device.
Given you can easily spend £150 on a pair of good quality pedals
anyway; the Assioma at £699 with precise power measurement built-in
represent fabulous value for money.
