The last five bikes I've owned, covering about ten years of riding, have all had 17" front wheels. (All the common 120/70/17 size, except the oldest which was 110/80/17, but I don't remember how it handled anyway) I'm wondering about switching to a bike with a 110/80/19" front tyre. I just wondered what difference the increased radius makes to handling of the bike? I guess there's extra gyroscopic force generated? But what does that mean in practice? Thanks!
