Incidentally i called into a well known bike shop in Derby today and watched in shock as a salesman tried to sell a lad my height a size 58 frame. The lad was about to shell out £2grand until i pointed out to him that he wouldnt even be a 56
The salesman had no IDEA.
The lad had got the seat lower than the bars and was stretching at that.
Oh dear,reminds me when i went into one of those golf discount shops,when i took golf semi seriously for a year,and i overheard a guy telling some poor beginner " you look like one of those guys that want to hit the ball long and straight" No Sh1t ....
