Riding on InfoCrank: Missive 1
Two weeks ago I got my InfoCrank orders, a 52×36 for both my son and myself.

Having been a powermeter user form many years now I have a sense of how they behave and in a way what to expect from them. My son has been using a Powertap for a while and to be honest, it hasn’t been as robust as my SRM’s have been over the years. Using a new powermeter was thus a little daunting.

We both ride Giant bikes and the included BB86 bottom bracket bearings fitted perfectly into our bikes. The 30mm bearings make the bikes feel more responsive and the purpose built cranks and Praxis chainrings are surprisingly solid. The mechanics of InfoCranks have been great so far.  Now, the powermeters themselves…

InfoCranks don’t need calibrating or zero offsetting. It’s an odd thing to get your head round if you have been used to doing it every time you get on a bike for many years. I did the first time out and they way to do it is to put the chain in the small ring and keep the cranks vertical, ie pointing directly to the ground. The figure you should get is ideally zero, -1 or 1. From then on just leave it, the strain gauges are bonded into a purposefully engineered cavity in the cranks, any expansion or contraction as the environment changes is matched and automatically compensated for.

So, riding them? What can you say, as a bike rider you need to trust your powermeter and after a while you get know what feeling in your body equates to what level of power your head unit tells you you are producing. We are on a week’s training camp in Majorca and within a few hours both Etienne and I feel at home and that we can trust our readings. And as the days progressed we soon forgot about them, exactly what you want to happen. We go for a ride, record our power, download the data, talk to our coaches and move on to the next day, perfect.


How do they hold up in the wind, rain and cold? So far, perfectly. Yesterday we were at the top of the island, descending the infamous Sa Colobra climb. Snow was on the ground, it had rained getting there, we were covered in grit and then we rode the 10k back up. We even saw Bradley Wiggins on his way down for one of of his Paris Roubaix preparation rides. Back at the hotel we had ridden 4 and a half hours, climbed 2000m, done 2 major efforts and had robust, consistent and comparable power data to look back on.

As the weeks progress I will write more about how InfoCrank performs, but first impressions are impressive.
