Hi everyone,
I've been driving myself mad with bike sizes lately (I know there are more important things in life but still..). I'm exactly in between sizes no matter which i look at things..
My APE index is even a solid 1....same arm span and height!! 186cm and 186cm !! So i guess it comes down to what do I feel more comfortable with. But even then I can find plusses and minuses all over the place.
I've been riding TREK FXs to and from work for a while now and the last one was a size Large that I found to be a bit bunched but it handled well. It gave my back a bit of jip so I then went a size up to an XL (22,5 inch) and all though I'm less cramped, it feels like I'm riding a tank and it's much less fun. Back is a bit better though.
So what would you do? A bit cramped and a bad back but lots of fun or a heavier sturdier ride minus the fun...
