Ah, well, I dunno about that? I naturally 'Lead ' with my right, , just because I am in the right frame of mind, you may say, but due to an injury to my Right leg , my left seems to be the stronger, more a case the right has atrophied , rather the left got stronger, have the dreaded Arthur Rightarse in my right hand,, and my left eye is the weaker, but I hear best with my left ear.
In fact I'd say I am a right basket case , as I've got older, but I still keep plodding on,
I prefer to start of with my left when cycling, mainly coz the right isn't what it was, but I unclip the right foot first, leaving me to lead with the left.
So perhaps there's some truth in what Matticus writes, but it's all hocum, I think, just coz I am a right handed person
