Just to clarify from my previous post no I didn't have an "incident" in fact I had an amazing ride even if the wind had other ideas.
Wow what a difference it makes climbing hills and being able to pull up and push down at the same time no more grinding in the easiest gear anymore in fact I dropped it down a couple of cogs and just kept the legs spinning.
My over all avg speed definitely felt faster but the wind on the straight sections put pay to a correct figure and in fact from the strava data I was avg 8.5mph and today was 8.9mph so without the wind it will be intresting to see if I can hit the 10mph barrier ready to start riding with a few others.
All in all very pleased with the pedals and they have already become second nature after only 9.3 miles.
