Q Factor updates. I read more of the company bumff, and they mentioned a Q-factor of 53.5mm ????? Not the 150 mm standard or SRM's quoted 147.5 mm.
So I wrote to them and got this in reply.
"thanks for your message and your comments make us proud.
We're talking about two different Q-Factors: the SRM Q-Factor is referred to Standard sizes talking about crankarms/cranksets, in our case we are talking about the Q-Factor, Standard sizesm referred to the pedals.
The Q-Factor is measured from the outside surface of the crankarm to the axis of the pedal (centre) and this distance is usually 53 mm,
This fundamentally mean that, if you're assisted by a biomechanikal, you don't need to make any kind of changings (cleats, shoes, etc) because our pedals and those ones that you have already installed on your bike (if they respect the standard Q-Factor) have the same size.
Hope to have well understood your question and replied properly.
Wish you a nice day and send you my best regards,""
This response came within the working day, having taken a tape out to the 2 bikes I was thinking of using both running Shimano Ultegra and Look pedals as near as dammit I get 53mm. Well for what its worth +/- 0.5 mm is not going to make a difference to my overall riding setup.
Other factors may or may not influence the decision to part with hard earned cash on these pedals but Q-factors are not one of them.
