Did you get some help getting the seat at the right height and distance from the handle bars. I never have done, but I know that some people swear by spending a bit of money getting their bike "fitted".
Of course it could be just because we are getting old and rusty.
Good point. No i didn't but i reckon it might be the angle of my cleats on the pedals. It feels like my feet are pointing inwards when I clip in. I need to take a look.
Yep, that's a good place to look - I have those egg-beater pedals on my road bike as well as MTB - they give a fair bit of lateral movement.
