I have been looking at sizing guides because I'm contemplating ordering a new bike and found out that I'm the totally wrong size for the bike I actually have.
I'm normal proportions and 5 foot 7, but according to the guide here
I should be 6 foot 2.
My issue is that my current bike feels very comfortable to me even though I can't stand flat footed if I stop the bike (just tried it now, I can only just put both feet on the ground at full stretch tip toes, it's a 29 inch wheel mountain bike if that makes any difference. Normally when I stop I just get off the seat and rest on one leg with the other foot on it's pedal. I have tried riding my wife's one which is a 26 inch and has the correct top tube length for me, but it feels horrible and I don't like the handling.
If I was to buy a big framed bike am I setting myself up for health issues in the long term, or should I just go with what's comfortable for me and not worry about it?
